The Warm Audio BUS-COMP is an all-analog, 2 channel, stereo VCA bus compressor based on classic circuitry that has provided silky smooth tone for decades. Stereo VCA bus compressors are masterful at controlling dynamics on many sources, but they have become widely known for their magic touch on stereo mixes.  The BUS-COMP will perform well on stereo mixes, drum mixes, drum overheads, acoustic guitars, keyboards, piano, orchestral instruments, voice-overs and an array of other sources. The BUS-COMP is primarily designed for stereo use, but it can be used just as successfully on individual mono sources. VCA bus compressors of this type have become widely loved for their ability to control dynamics effortlessly but also for the added tone and depth they provide to the audio signal that passes through them, even when no compression is applied.Re-creating legendary VCA bus compressor technology was the focus of the BUS-COMP’s design, however, adding options and improvements was just as important to us during its development. One feature we are proud to boast is the BUS-COMP’s ability to have USA made CineMag transformers inserted into the signal path driven by fully discrete operational amplifiers. With a single push of a front panel switch, these custom USA made transformers are inserted into the audio’s path providing increased depth, tone and vibe!As with all of the products we develop here at Warm Audio, the BUS-COMP was designed with a price point in mind. With efficient, modern manufacturing techniques we are proud to bring this boutique quality, classic VCA bus compressor to the market at a quality-to-price ratio previously unseen. More studios than ever before will now have access to analog quality VCA bus compression. Our desire is for all musicians to be heard the way they want to be heard and we feel the BUS-COMP is the perfect tool to perfect any mix!Technical Specifications* All analog, 2 channel, stereo VCA bus compressor* Based on legendary VCA bus compressor technology* Selectable discrete opamp stage with CineMag USA transformers* External side chain source select* SELECTABLE HI-PASS FILTER: 30, 60, 105, 125, 185 HZ* COMPRESSOR ENGAGE SWITCH FOR EASY A/B COMPRESS VS.

The COMP-54 is a one-channel vintage style Compressor. The signal path uses only discrete components like resistors, capacitors and transistors. The line input and output are transformer balanced and the unit also has a third interstage transformer.This is the way audio components were built before integrated circuits became available. IC´s are small and cheap and they are widely used in most modern designs. It is clear though that audio components built with modern technology doesn´t always provide the best perceived sound quality or character that the modern user desires. On the contrary, the subjective sound quality delivered by vintage equipment is often prefered over the one delivered by modern units. This is the reason why so many vintage audio components are cloned and produced again and also why the vintage originals are often very expensive on the second hand market.The class-A circuit used in the COMP-54 is similar to the one in the classic 2254 compressor that was designed in 1969. It quickly became a legend due to it´s totally unique sound character that is warm, smooth, sweet and musical. These characteristics have been heard on countless recordings through the years and it is a versatile sound that works very well on most sound sources and in most genres. The essence of this sound is now available at a surprisingly low cost, making it available to nearly everyone.The COMP-54 uses a diode bridge as the gain control element, a method that is revered for its smooth way of operation. Some of the most sought after vintage compressor designs, like the 2254, 2264, 33609, Siemens™ and EMI™ used the same basic design.The controls in the COMP-54 are very flexible covering broad ranges of Ratio, Attack and Release times, including two Auto positions. All controls except the Gain make-up one are stepped for easy resetting and stereo matching.There are three selectable sidechain high pass filter frequencies available to handle special situations.The Bypass switch is a true bypass where a relay switches the complete circuitry in or out. The IN/OUT switch makes it possible to switch the compression on and off while retaining the coloring from the transformers and the electronic circuitry.The meter can show output level or gain reduction. It is also possible to link two units for stereo operation.

Classic API Compression for the Modern Studio The API 2500+ Stereo Bus Compressor joins the company’s regular lineup, bringing all that formidable dynamics-shaping power to your rack in a sleek, space-saving 1U chassis. The API 2500+ model added a sophisticated Mix/Blend circuit to API’s venerable design coming form the anniversary edition. API’s flagship compressor delivers the inimitable sound of iconic API compression along with unparalleled parametric control. The result is an incredible-sounding, versatile, world-class stereo bus compressor capable of handling any audio production task. Meticulously designed to deliver a broad range of compression options and features not found on most compressors, the API 2500+ delivers warmth, clarity, and punch, whether used for nuanced dynamics control, brick-wall limiting, or anything in between. Parallel compression done right The Mix/Blend circuit found on the API 2500+ does a lot more than the simple wet/dry blend pot found on many modern compressors, giving you the option of either crossfading or parallel mixing of the compressed and uncompressed signals. First of all, the circuit can be hardwire relay bypassed entirely to deliver a purer signal than a standard blend pot simply maxed out to fully “wet” — a feature golden-eared engineers will appreciate. Next, when engaged and set to X (Cross), the Mix control lets you crossfade between fully uncompressed and fully compressed, literally increasing one while decreasing the other. In || (Parallel) mode, the MIX control effectively dials in your desired amount of compressed signal to blend in with the uncompressed signal, which remains constant. In case you’re wondering; trust us — these two active modes do sound and behave differently and you’ll quickly find uses for each. Equip Your Studio with Iconic API Compression If you’re after versatile compression, the API wrote the book. While the 2500+ is set up for stereo compression, you can also use it dual-mono. However you use it, though, you’ll have a range of compression styles to dial in — all highly musical, all incredibly usable. The 2500+ sports API’s patented Thrust circuit, a proprietary loudness contour that packs a powerful punch, imbuing each octave with the same energy (instead of half the energy as the next lowest one, as is the normal state of affairs).The Old/New Tone Type switch lets you choose between classic feedback and modern feed-forward compression styles. Whether you’re using it for drum stems, guitars, bass, vocals, or as a stereo bus compressor to pump up your mixes, the 2500+ delivers the iconic API analog sound and "slam factor" that has been relied on by recording engineers and heard on countless hits for a half century. Simply put: every serious studio needs the API 2500+. Incredibly versatile, highly musical When you choose API, you know you’re getting legendary sonic character. And with the API 2500+, you’ve got a range of character to choose from. To start, the 2500+ is equipped with API’s patented Thrust circuit before its RMS detector, which delivers punchy, old-school low end. There are also two types of compression onboard the API 2500+ — Old and New. The Old style uses the feedback type of compression in which the detector is placed after the VCA (as found on the classic API 525), while the New style uses a feed-forward type for a faster response typical of many popular modern compressors.The API 2500+ is stereo-ready, but sports a variable link between the left and right channels, so you can independently put the channels to work on your mono sources. Whatever way you use it, you’ll appreciate having API’s auto-makeup gain button on the output stage. It lets you vary the API 2500+’s threshold or ratio, while automatically maintaining a consistent output level. Sidechain input for creative ducking Every dynamics processor has a sidechain circuit that examines the signal and determines how much the VCA will reduce gain — but not every unit provides access to its sidechain. In compressors without a separate sidechain input, your main input signal is, essentially, compressing itself. With compressors that have a separate sidechain input — like the API 2500+ — you can introduce a different signal that determines the compression action on the main signal.An overt illustration of sidechaining is the “pumping” effect that’s popular in EDM production. A control signal — let’s say, a bass drum — is plugged into the sidechain input, triggering the detector and causing the main signal — a synth bass, in this example — to "duck," under each bass drum hit. This clears the way for maximum kick drum impact. Another classic use is for auto-ducking music under a voiceover, as in a radio commercial spot. Sidechaining can be used creatively in many ways, limited only by your imagination! API — the legendary American pro audio company No American pro audio company is more iconic than API. Launched in 1968 by Saul Walker, Automated Processes Inc. began building quality consoles for broadcast applications. Soon, the company’s products found favor with recording studios, and a string of industry-leading innovations (including the 500 Series module, the first VCA, computerized console automation, and more) followed. API produced the 2520 amplifier, one of the most famous op-amps in the recording industry, and their consoles and products found homes in such iconic studio facilities as the Hit Factory, Record Plant, Ocean Way, Sunset Sound, and many others.In fact, there are over 700 vintage API consoles around the globe — many of which are still in use. And the company certainly isn’t resting on its laurels; today’s API products give you the same unbeatable combination of utility, innovation, and great sound. That’s why, at Sweetwater, the name API commands reverence.

Mastering Compressor As a mastering compressor, IRON is inspired by the legendary vintage tube compressors à la Fairchild, Collins or Gates and has been developed in a way to give modern productions more energy and power with the advantages of the 120V technology. Input & Output Input and output levels are switchable in a control range of +/- 12dB. An increase of the input level leads to more intensive compression. When mastering full scale material, the reduction can be useful. The output is used to adjust the level ratios of input and output. Attack & Release The time parameters Attack and Release are switchable in six steps from Slow to Fast. The times vary depending on the rectifier circuit selected. Side Chain EQs With the side chain EQs, compression can be focused on frequency ranges. In addition to an inserted EQ, there are four internal EQ presets with a partly complex frequency response. Rectifier The tube stage is controlled by a rectifier circuit. There are six diode control characteristics generated by germanium, silicon and LED diodes or combinations thereof. Variable-Bias Limiter/Compressor The IRON Mastering Compressor is a variable-bias (variable µ) limiter/compressor from the basic concept. IRON works on the principle of the bias controlled remote cutoff tube. Parallel to this, a medium-variable-bias triode (sharp-cutoff tube) with a steeper characteristic is connected. The tube bias voltage (BIAS) can be adjusted in three steps. The tubes are integrated into special Lundahl manufactured balanced high-level double core mu-metal-iron transformers. AirBass & Tape Roll-Off The compressor is followed by a passive filter network with two equalizer presets: AirBass and Tape Roll-off. The AirBass filter boosts low and high frequencies by about 1.5 dB and the Tape Roll-Off filter emulates the typical frequency response of a tape machine. Link All functions can be set via switches and the threshold via a rasterized potentiometer which makes recall easy. The settings of Threshold, Bias, Attack, Release, Rectifier and Side-Chain-EQs are transferred from the right side (channel 2) to the left side in Link Mode, in which the compressor operates with summed control signals. Auto-Bypass Channels 1 and 2 are activated with the large illuminated IDEC switches. In Auto Bypass mode, the channels are automatically switched on and off, which leads to a more objective assessment. The Interval control is used to adjust the time window continuously between two and 20 seconds.

If there is a single piece of analogue processing equipment that is synonymous with SSL, it must be the SSL Bus Compressor. From the very first commercially released SSL 4000B console in 1976 and through many generations of SSL consoles that have followed, the Bus Compressor has always been the stalwart of the console centre section. For many of the world’s top engineers and producers, the Bus Compressor continues to be the most relied upon processing tool for making mixes sound bigger and more complete, with drive and energy from adding that legendary SSL glue and punch.

The Chandler Limited RS124 packs three legendary Abbey Road RS124 compressors into one chassis. Over the decades since the Abbey Road RS124 graced Beatles' recordings, there were attempts to re-create the hardware from sketchy information; none of these efforts fully realized the elusive musical soul of the original EMI unit. Schematics relayed only so much of the design. So Chandler turned to historic units provided by Abbey Road, as well as handwritten modification memos that would prove essential in understanding the essence of the beast. They succeeded! The Chandler Limited RS124 nails the behavior and sonics of the original - which Peter Cobbin, Abbey Road's Director of Engineering, describes as "pure cream being drizzled slowly into and over a mix.”Chandler Limited RS124 Compressor at a Glance:Put a legendary compressor in your rackWhat the RS124 can do for youYour sonic obsession: Chandler's missionPut a legendary compressor in your rackThe Abbey Road RS124 is a holy-grail compressor. It has a lovely, colorful sound, and a colorful back story. In the late 1950s, EMI procured several Altec 436B tube compressors for their London studios. In 1960, EMI engineers modified them so heavily (and as they were never used outside of Abbey Road), they felt comfortable re-naming them, and thus, the RS124 was born. Imagine getting your hands on the compressor that was used on virtually every Beatles recording made at Abbey Road Studios! The RS124 lives on, courtesy of Chandler Limited. The Chandler Limited RS124 sounds incredible - and like no other compressor you've ever used.What the RS124 can do for youThe RS124's smooth, creamy sonic character and transient-taming prowess comes without a hint of muffling during heavy compression. Once you use the Chandler Limited RS124, you'll find out what Abbey Road engineers quickly realized: this is an indispensable tool for tracking, bus compression, mixing, and mastering. Along with original Input, Output, and Recovery (release) controls and the unique Hold setting, the Chandler Limited RS124 ups the ante with modern features like adjustable attack, selectable output impedance, and the cutting-edge SuperFuse. Google up some photos of Abbey Road Studios in the 1960s. You will see an RS124 in just about every control room. Wouldn't it be great to have one (or two) in yours?Your sonic obsession: Chandler's missionRecording engineers are always looking for fresh tonal colors when tracking, mixing, and mastering - it's an obsession. Chandler Limited feeds this addiction with their innovative take on the technologies of the past. They start with painstaking component selection. Every parts list reads like a 50-year-old document.

Although the TG12413 was never offered commercially, Chandler Limited has resurrected the beast from the original design specifications and circuit board drawings as provided by Abbey Road Studios and EMI. This compressor/limiter features an all-discrete circuit with transformer-balanced input and output that produces smooth, pleasing distortion. For a distinctive Abbey Road sonic flavor, put Chandler Limited's TG1 Abbey Road Special Edition limiter in your rack.At a Glance:A re-creation of the amazing-sounding classicYou're in good company: The Beatles, Pink Floyd, The Stones...Pure vintage sound from discrete circuitry and transformer-balanced input and outputA re-creation of the amazing-sounding classicThe Chandler Limited TG1 Abbey Road Special Edition is a re-creation of the classic EMI TG12413 limiter used in custom EMI and Abbey Road recording and mastering consoles from the late 60's. The TG Limiter was originally designed to have the characteristics of the Fairchild 660/670, which was adored by many EMI engineers - including Geoff Emerick - but ended up with a very special sound all its own. These rare pieces were never commercially available and only EMI-owned studios had access to them. The Chandler Limited version has been remade from the original design information and circuit board drawings as provided by Abbey Road and EMI to ensure extreme authenticity.You're in good company: The Beatles, Pink Floyd, The Stones...TG equipment was used on many classic records and this Limiter was featured on every channel of TG consoles used to record The Beatles' Abbey Road, several Pink Floyd records, including Dark Side of the Moon, Paul McCartney, and the Rolling Stones. When you use Chandler Limited's TG1 Abbey Road Special Edition limiter, you'll immediately hear the sonic ancestry. This limiter sounds totally gear.Pure vintage sound from discrete circuitry and transformer-balanced input and outputThe Chandler Limited TG1 Abbey Road Special Edition limiter features an all discrete circuit with transformer-balanced input and output. The limiting element is a rarely seen diode network that produces smooth, pleasing distortion. The warm open sound, often compared to the holy grail Fairchild 670, is very punchy, while maintaining exceptional clarity and high frequency response. You've simply got to hear one in action to fully appreciate a limiter of this magnitude.Selectable Compression/LimitingTHD control lets you bypass Comp/Limiting but still pass audio through the circuitryTransformer balanced inputs and outputsNew input control provides better control at lower amounts of compressionChandler Limited and their associated logos are registered trademarks of Chandler Limited, Inc.

The Chandler Limited RS660 tube compressor/limiter is Inspired by the classic program levelers used by engineers at EMI Abbey Road Studios in the 1960s. From the Beatles to early Pink Floyd, the historic Fairchild 660 and EMI RS124 compressors shaped the sound of countless iconic recordings that emerged from the legendary London facility. The eminently musical performance of these units stemmed from their “vari-mu” circuits, which generated program-dependent gain reduction by automatically adapting to the dynamics of the incoming signal to efficiently manage levels while allowing vocals and instruments to bloom with vibrancy and punch. Meticulously handcrafted by Chandler Limited, the RS660 builds upon the sonic magic of these rare, prized vintage compressors in an innovative modern design that advances the state of the art in dynamics control.The best of vintage and modernBuilt around the venerable 6386 mil-spec vacuum tube, the RS660 is, not surprisingly, engineered more efficiently than the coveted vintage units that inspired it. After all, today’s cutting-edge technology and advanced materials science enable high-precision design and manufacturing unimaginable back in the 1960s. No mere reproduction, however, the RS660’s elegant and refined compression circuit is painstakingly tuned to deliver a sound that combines the sought-after sonics of its Fairchild namesake along with modern flexibility, vanishingly low noise, and impeccable behavior, no matter how hard you push it. The RS660 is a professional tool that can tame the dynamics of any source, from subtle vocals to hard-hitting drums — and everything in between. The single-channel RS660 is also linkable to a second unit for stereo operation — ideal for pumping up drum buses and complete mixes.Built like a tankBack in the day, pro audio gear was handcrafted using military-grade materials and through-hole components — and that’s how Chandler Limited builds its equipment today in Shell Rock, Iowa. Accordingly, the RS660’s vintage-inspired circuitry is ensconced in a rugged dual-rackspace chassis with a stout faceplate, a beefy internal power supply, transformer-balanced XLR I/O, and selectable output impedance. As did the classic compressors that inspired it, the RS660 provides a tactile sensory user experience. The throw of its pots engenders a confident, spoon-in-honey feel that, at first touch, suggests you’re using a serious piece of high-end kit — and the world-class results confirm it. The Chandler Limited RS660 represents a significant advancement in the art of signal dynamics processing.Features:Designed in cooperation with EMI Abbey Road StudiosSingle-channel, linkableTransformer-balanced I/O, XLROutput impedance: selectable, 200/600 ΩContinuous input and output gain controlTime constant: 7 positions, steppedModes: THD, Comp, LimitStereo Link: switchable, 1/4-inch jackInternal power supply

The Distressor is an automatic gain (or volume) control device (AGC in engineering terms) designed for pro audio (music) applications. Basically, it electronically controls the volume of just about any source in a very pleasing, and "musical" manner - adding fullness, intelligibility, and especially in the Distressor's case - excitement.This type of device is often called a "limiter" or "compressor" by audio industry people. Its most probable uses will be in recording studios, live sound situations, movie sound production, and radio broadcast production.

A new version of the Phoenix soft knee stereo valve compressor, the Phoenix Standby: new features include a standby switch which is provided to extend valve and capacitor life. When in 'standby' the HT current through the valves is only 50% of the normal value. The zero level meter adjusters have now been front to the front panel to make calibration easier and to avoid having to take the unit out of the rack.The Phoenix is a twin channel 'vari-mu' device. Compression ratio starts low and increases gradually so that compression can be subtle and natural, but compression effects can occur when driven hard. Very low noise. Continuously variable controls for Gain, Attack, Release, Threshold and Output Level. Stereo link for compressing a group (eg. drums) or a complete mix.The Phoenix enhances vocals & individual instruments by being unobtrusive, gently 'warming' sounds and making solos sound more powerful. ItΉs impressive on overall mixes & can give a digital mix 'reality'. ItΉs also excellent for compression effects. Try drums with a 'thump' attack (i. e slowest) & fast release.Key Features All valve design for greater presence and naturality.Completely free from solid state additives.Transparent compression.Punchy when pushed.Drive it hard for compression effects and distortion.Absolutely flat frequency response over entire audio range and beyond.Minimal phase shift giving a crisp and warm sound.

The Phoenix HG 15 is a single channel version of our classic Phoenix Stereo Compressor, having the same gentle “variable mu” type compression curve, though it becomes near to a limiter at high compression levels.The gain has been boosted to suit mic inputs, particularly valve and FET condenser types, but many moving coil types, such as Shure, Audio Technica, etc. are fine to use if the sound source is quite loud or close-miked.With the Threshold switch set to Comp Out it’s a clean mic/line amp, now add a little Active Eq, “Presence” and/or “Air” to brighten the sound, then switch in some compression and achieve that gentle “super-natural” effect that only Thermionic Culture can give you.The Output Level control acts as a reverse linear attenuator after the electronics, and can be used simply to reduce level if feeding a low level input, or to add “Attitude” by reducing the output and increasing the input.  If you’re working from line level, it’s OK to switch the input from “Line” to “Pad” but ensure the +48v switch is OFF!2 HG15s can be linked together for stereo use by a phono-phono lead from the Link socket at the rear.   There’s a Side Chain Bass Cut switch, which can also be useful in mono operation. To sum up, The Phoenix HG15 is ideal as just a mic amp for vocals, violins, horns, guitars…… especially when using a high output mic like the U87.  Then having the ability to add compression and a bit of eq.Features:High Gain Mic Amp/Compressor/EQ with super-natural valve sound;Based on Phoenix design with 52 dB gain available;Fully Balanced circuit with XLR in/out connectors;+48v Phantom power available;Threshold control has 7 way switch with Compressor Out position;Time Constant switch has 6 combinations of Attack & Release;Side Chain Bass Cut;Presence and Air switches to boost mid and high top with In/Out switch;Bass Cut to roll off low bass;2 valves, 6AQ8EH input and 12AT7/ECC81 output;Solid State side chain! ;Link socket to connect 2 HGs for stereo buss operation, etc.

The Shadow Hills Mastering Compressor has extraordinary functionality, and also provides mastering grade compression and limiting for tracking and mixing. Essentially it is two compressors in series, per channel, that can act in stereo, or dual mono. First comes our mastering grade electro optical compressor, followed by our discrete Class-A compressor/limiter. Both feed our switchable custom output transformers, Nickel, Iron, and Steel. There is enough gain in each section to overdrive the hottest tape, or clip your converters, if you're into that sort of thing.The input stage is transformer balanced, followed by our fully discrete optical compressor. This section utilizes the same T4B optical attenuator as the LA2A and LA3A, but is optimized for mastering. The second stage is our discrete Class-A VCA compressor. There are no electrolytic caps or IC chips in the audio path. There are six ratios: 1.2 to 1, 2 to 1, 3 to 1, 4 to 1, 6 to 1, and 10 to 1. There is six attack settings: .1, .5, 1, 5, 10, and 30 milliseconds. And there are six release times selectable: .1, .25, .5,8, 1.2, and Auto. There is an insertable filter in the side chain to limit pumping with bass heavy material. Lastly the signal goes through our new Shadow Hills custom transformer-switching network.The first position is Nickel, which is our custom version of a famous L. A. custom console. Next is Iron. In this mode the signal goes through our op-amp and into a Class-A output stage then to our custom Iron transformers, the last transformer position is Steel. These selections allow you to choose between different output transformers that are in effect: clean, colored, and dirty, respectively.The optical section has a hard-wired bypass that completely removes it from the signal path, and the Class-A VCA compressor is also hardwire bypassable, completely removing it from the chain. It is possible to independently bypass both compression sections and have your signal go through the input transformer and transformer selector only. There is also a hardwire bypass for the entire compressor, effectively a strait wire in and out of the box. So besides being a mastering grade, and highly functional buss compressor, it serves as an excellent tracking compressor.For instance, you might call up the chain of the optical compressor, then to the Class-A output and Iron transformer, for vocals, or select just the Class-A VCA compressor with a 10:1 plus the Steel transformer for crushing some room mics, and on and on.The metering can reflect, optical gain reduction, discrete gain reduction, or output level. The Magic eye tube follows the output meter to act as a peak meter.All 17 of the rotary switches are detented. The front panel is engraved. The knobs are bake-lite 

The Chandler Limited EMI TG12413 Zener Limiter is the definitive TG limiter, released in honor of Abbey Road Studios' 75th birthday. The brainchild of Chandler Limited designer Wade Goeke, the Zener Limiter is based on the classic EMI circuits used to record The Beatles and Pink Floyd. This latest EMI limiter carries on the tradition of EMI limiters started in 1956 with the RS114 tube limiter, and continued with 1966's RS168 Zener Limiter (a component of the TG12345 console channel in 1968), and the TG12413 in '74. Start with the essence of the classic RS168, add modern functionality, and you have the Chandler Limited EMI TG12413 Zener Limiter.Chandler Limited EMI TG12413 Zener Limiter at a Glance:Classic compression and limiting, with modern flexibilityExercise iron-fisted control over your dynamicsYou get natural compression, scrumptious-sounding limiting - and a blend of the twoClassic compression and limiting, with modern flexibilityThe original TG Limiter was designed to replace both the Fairchild 660 and the EMI-modified Altec 436/RS124 - two certified classics, revered for their dynamics-shaping prowess. The Altec unit was known for its natural, organic compression, while the Fairchild - with its fast, sub-millisecond onset and extremely soft-knee compression curve - is perhaps the most lusted-after (and imitated) limiter ever made. The Chandler Limited EMI TG12413 Zener Limiter gives you the sonic mojo of these two classics - and goes several steps beyond.Exercise iron-fisted control over your dynamicsThe Chandler Limited EMI TG12413 Zener Limiter gives you the power to impose your will on your dynamics. Starting with the powerful vintage TG limiter circuits, Chandler Limited gives you added features and flexibility in the form of controls such as switchable input impedance (for hard or soft driving of the unit), 11-position attack, 21-position release, and side chain filtering, as well as Comp 1, Comp 2, and Limit settings.You get natural compression, scrumptious-sounding limiting - and a blend of the twoCOMP 1 is a 2:1 ratio with slower time constants than originally designed by EMI engineers to emulate the Altec 436/RS124 EMI-modified Altec compressors. Limit mode is much faster and designed to emulate the response curves of the revered classic Fairchild 660. COMP 2 is a new setting that puts you halfway between the two original settings, essentially giving you the compression curve of Comp 1, with the faster release times characteristic of Limit mode. Whether you use it for tracking or mastering, with its sonic pedigree and effective controls, the Chandler Limited EMI TG12413 Zener Limiter is a must-have for huge, punchy mixes.Chandler Limited EMI TG12413 Zener Limiter Features:Gives you the sonic mojo of two classics: the Fairchild 660 and the Altec 436/RS124COMP 1 mode is a 2:1 ratio with slower time constants reminiscent of the Altec 436/RS124Limit mode is faster and designed to emulate the response curves of the revered classic Fairchild 660COMP 2 is a new setting that puts you halfway between the two original settingsChandler Limited and their associated logos are registered trademarks of Chandler Limited, Inc.

The Chandler Limited EMI TG12345 Curve Bender EQ is the definitive TG equalizer, released in celebration of Abbey Road Studios' 75th birthday. The brainchild of Chandler Limited designer Wade Goeke and Abbey Road senior engineer Peter Cobbin, the Curve Bender is based on the vintage EMI TG12345 console used on Beatles and Pink Floyd recordings. This latest EMI equalizer carries on the tradition of EMI EQs that began in 1951 with the RS56 (cheekily dubbed "the Curve Bender" by EMI designers), and continued with the 1968's TG12345 and TG12412 in '74. A classic design - the gorgeous-sounding TG12345 - juiced with it with modern features. That's the Chandler Limited EMI TG12345 Curve Bender.Chandler Limited EMI TG12345 Curve Bender EQ at a Glance:A fully featured version of a classic EQPowerful functionality gives your serious sound shaping mojoYou get the best of both worlds: vintage warmth, plus modern featuresA fully featured version of a classic EQThe Chandler Limited EMI TG12345 Curve Bender EQ is the embodiment of a dream. It was during his mixing of numerous Beatles-related projects (Anthology, Yellow Submarine, Imagine, etc.), it occurred to Peter Cobbin that having a fully featured and highly flexible version of the original desk EQ units would be invaluable. After Wade Goeke presented him with a working version of the legendary console equalizer, Peter realized he could "have it all," and set Wade to building the perfect beast.Powerful functionality gives your serious sound shaping mojoPeter had requested four bands, and filters based on the slopes of the original console - but with overlapping and expanded options. In the final production unit, the 9 selections of the original TG12345 had become 51 EQ points. Wade also added a multiply switch that increases boost/cut up to 13.5dB (as well as sharpening the Q), in addition to filters and bell/shelf selections on the high and low bands.You get the best of both worlds: vintage warmth, plus modern featuresThe result is the Chandler Limited EMI TG12345 Curve Bender - a classic equalizer from the glorious history of EMI and Abbey Road that's come full circle, morphing into a modern powerhouse EQ perfect for all your recording, mixing, and mastering needs.Chandler Limited EMI TG12345 Curve Bender EQ Features:A fully featured version of a classic EQThe best of both worlds: vintage warmth, plus modern features51 EQ pointsMultiply switch increases boost/cut up to 13.5dBHigh pass and lowpass filters and bell/shelf selections on high and low bandsChandler Limited and their associated logos are registered trademarks of Chandler Limited, Inc.

The BC1-THD provides smooth bus compression that applies for both mixing and tracking. Engineers call it “The Magic Glue” when the BC1-THD’s transparent compression strengthens mixes without compromising clarity. The built-in blend control makes it easy to apply parallel compression by adjusting the blend of dry and compressed signal. A switchable sidechain filter can be applied which makes the BC1-THD less responsive to low frequency energy. The THD function adds more harmonics to the signal and the “grab” mode selects a harder threshold knee on all four ratio settings. Smooth and transparent compression will never go out of fashion.

The MANLEY VARIABLE MU® LIMITER COMPRESSOR has been our best selling product for many years. It is one of the very few compressors that has become a real standard in Mastering studios and contributed to most hit records over the last decade and probably the next. "Mu" is tube-speak for gain, and Variable Mu® is our registered trademark for this limiter compressor. It works by using the "remote cut-off" or re-biasing of a vacuum tube to achieve compression. The precious vintage Fairchild 670 also uses this technique and is one of few all-tube compressor to do so, that we know of. Even the side-chain has glowing rectifier bottles. How’s it work? The unique 5670 dual triode is at the center of the peak-reducing and compression action constantly being re-biased by the vacuum tube rectified side-chain control voltages which cause this tube to smoothly change its gain. Just like that.The COMPRESS mode is soft-knee 1.5 to 1 ratio while the sharper knee LIMIT mode starts at 4 to 1 and moves to a more dramatic ratio of 20 to 1 when limiting over 12dB. Interestingly, the knee actually softens as more limiting is used. Distortion can be creatively used by turning up the Input and turning down the Output while using very little or no compression. See the gain reduction curves here!You might notice that the Variable Mu® Limiter Compressor has a ganged input control, but do not jump to conclusions that it is mono-unfriendly. Track away! There are separate threshold and output controls to make compensations with plus you can always adjust your individual source levels elsewhere, right? The advantage of the stereo input control becomes dramatically clear when you switch to LINK mode, and that’s what our Variable Mu® Limiter Compressor does better than anything else: final mix, 2-track, or mastering limiting and compression. Like one reviewer put it: “It’s like pouring a bowl of sweet cream over the mix.” Mmmmmm. Yummy.

The COMP-554 MKII is the 500 series rack version of the COMP-54 MKIII with some additional features. The COMP-554 MKII is a one-channel vintage style compressor for the 500-format. The signal path uses only discrete components like resistors, capacitors and transistors. The input and output are transformer balanced and the unit also uses a third interstage transformer. This is the way audio components were built before integrated circuits became available. IC´s are small and cheap and they are widely used in most modern designs. It is clear though that audio components built with modern technology doesn´t always provide the best perceived sound quality or character that the modern user desires.On the contrary, the subjective sound quality delivered by vintage equipment is often prefered over the one delivered by modern units. This is the reason why so many vintage audio components are cloned and produced again and also why the vintage originals are often very expensive on the second hand market. The class-A circuit used in the COMP-554 MKII is similar to the one in the classic 2254 compressor that was designed in 1969. It quickly became a legend due to it´s totally unique sound character that is warm, smooth, sweet and musical.These characteristics have been heard on countless recordings through the years and it is a versatile sound that works very well on many sound sources and in many genres.

The SR22 Dual Channel Compressor features two channels of API's patented award-winning compressor circuit in a rackmount unit with internal power supply. This same compressor circuit was originally designed into the legendary ATI Paragon analog live mixing console. Each channel includes the patented THRUST® circuit, which protects the sensitive high frequency content of the audio signal, even under the most vigorous of compression ratios. The perfect companion to the new SR24 Dual Channel EQ, the SR22 provides comprehensive, easy-to-use control along with classic analog VU meters for monitoring output and gain reduction. The two channels can also be linked for use as a stereo compressor with true RMS power summing of the left and right signals.

The SR24 is a two channel, four band equalizer in a two rack-space chassis. With a dedicated knob and/or switch for each control function, the SR24 is easy to use; by utilizing continuously-variable controls for both the frequency and boost/cut, the SR24 can be very precise in applying equalization to the selected audio material. The SR24 circuit design is deeply rooted in API's history. From the late 1970's to the early 1980's, an audio company called "APSI" manufactured consoles and equalizers. Their 562 module was a 4-band, fully parametric equalizer which was designed by APSI and sold through API. Over the last several decades, these EQ modules remained a favorite among many studio engineers, but have become increasingly difficult to find. The SR24 is a faithfully re-engineered version of the original 562, offering the user 2 channels of classic analog EQ in one rackmount unit.

The API Select T25 is a classic 2-channel, FET feedback-style compressor/limiter with a Class-A tube output stage that utilizes a custom API transformer. Built with 12AT7WC and 12BH7 dual-triode vacuum tube, the T25 represents a new direction in API's line of compressors. It offers the user a powerful and flexible feature set, including the ability for use in either dual mono or stereo mode, and is carefully engineered to deliver classic tube performance. The T25 excels at delivering the unmistakable sound of API and features our industry-exclusive Five Year Warranty.

The CX2310 stereo 2-way/mono 3-way crossover provides amazing-accurate audio frequency separation, thanks to its state-of-the-art circuitry, superior-grade components, ultra low-noise op amps and balanced I/O connectivity. Additionally, the CX2310 features an independently-adjustable Subwoofer Output, effectively providing an extra low-frequency band a control range from 10 - 235 Hz. By using 1% metal film resistors, along with other extremely tight-tolerance components, the CX2310 is able to guarantee surgically-precise frequency selection with incredibly-low thermal noise. Put simply, the easy-to-use SUPER-X PRO CX2310 is one of the best-sounding crossovers in its class! Sound Quality When a sound system is properly tuned, it becomes powerful, balanced and efficient. Bass content is punchy and tight, with vocals and instruments that are rich, crisp and well defined. The CX2310 crossover’s accurate signal processing protects critical loudspeaker components and improves overall system efficiency. All Input and Output connections are balanced/unbalanced XLR and feature 25 Hz Low Cut filters for low-frequency driver protection – plus Mute and Phase Invert switches, making troubleshooting even a large system – virtually effortless! What’s a Crossover? Chances are if you’re reading this, you already know what a crossover is – and you know that you need one. But if you are new to multi-way PA systems, here's a brief overview. Loudspeakers (which we call transducers) convert electrical signals into sound waves. And no matter how well a transducer is designed or made, it simply cannot reproduce the entire audio spectrum all by itself. Low-frequency sounds tend to push a transducer to the maximum, making it impossible for that same transducer to reproduce the treble content with the sound quality it deserves. (Try singing high falsetto next time you’re bench-pressing your limit!) That's why high-quality sound systems use multiple speakers (woofers and tweeters) to spread out the work. While the woofer (usually the larger transducer) does all the heavy lifting, the tweeter can easily handle the high-frequency content. Three and four-way systems distribute the work even more, allowing the individual transducers to reproduce the frequency range for which they were designed. It is the crossover’s function to divide these tasks between the various amplifiers and transducers. Divide and Conquer The CX2310 provides two modes of operation: 2-way stereo, for Left and Right Lows (woofers) and Highs (tweeters); and 3-way mono, for Lows, Mids and Highs. In either mode, there is an additional output provided for a mono Subwoofer, with its own Frequency and Level controls. This extra feature effectively turns the CX2310 into a stereo 2-way + mono 1-way, or a mono 4-way frequency crossover. The Subwoofer Output is presented in mono, since people perceive extremely-low bass frequencies as being omnidirectional. For your convenience, the CX2310’s front panel features an elegant and easy-to-read LED matrix, so you can see at a glance which operating mode has been selected – and which controls are currently active.

Mastering Compressor As a mastering compressor, IRON is inspired by the legendary vintage tube compressors à la Fairchild, Collins or Gates and has been developed in a way to give modern productions more energy and power with the advantages of the 120V technology. Input & Output Input and output levels are switchable in a control range of +/- 12dB. An increase of the input level leads to more intensive compression. When mastering full scale material, the reduction can be useful. The output is used to adjust the level ratios of input and output. Attack & Release The time parameters Attack and Release are switchable in six steps from Slow to Fast. The times vary depending on the rectifier circuit selected. Side Chain EQs With the side chain EQs, compression can be focused on frequency ranges. In addition to an inserted EQ, there are four internal EQ presets with a partly complex frequency response. Rectifier The tube stage is controlled by a rectifier circuit. There are six diode control characteristics generated by germanium, silicon and LED diodes or combinations thereof. Variable-Bias Limiter/Compressor The IRON Mastering Compressor is a variable-bias (variable µ) limiter/compressor from the basic concept. IRON works on the principle of the bias controlled remote cutoff tube. Parallel to this, a medium-variable-bias triode (sharp-cutoff tube) with a steeper characteristic is connected. The tube bias voltage (BIAS) can be adjusted in three steps. The tubes are integrated into special Lundahl manufactured balanced high-level double core mu-metal-iron transformers. AirBass & Tape Roll-Off The compressor is followed by a passive filter network with two equalizer presets: AirBass and Tape Roll-off. The AirBass filter boosts low and high frequencies by about 1.5 dB and the Tape Roll-Off filter emulates the typical frequency response of a tape machine. Link All functions can be set via switches and the threshold via a rasterized potentiometer which makes recall easy. The settings of Threshold, Bias, Attack, Release, Rectifier and Side-Chain-EQs are transferred from the right side (channel 2) to the left side in Link Mode, in which the compressor operates with summed control signals. Auto-Bypass Channels 1 and 2 are activated with the large illuminated IDEC switches. In Auto Bypass mode, the channels are automatically switched on and off, which leads to a more objective assessment. The Interval control is used to adjust the time window continuously between two and 20 seconds.

The drawback is that audio components built with modern technology doesn´t always provide the best perceived sound quality or the type of character that the modern user desires.The subjective sound quality delivered by vintage equipment is often prefered over the one delivered by modern units, a situation that is even more obvious now when music is recorded with clean-sounding digital audio equipment.This is the reason why so many vintage audio components are cloned and produced again and also why the vintage originals are often very expensive on the second hand market.The circuit used in the COMP-2A is based on a classic design that was originally produced in the early 1960s and it was initially intended for broadcast applications. It uses an electro-luminescent panel and a photoelectric cell to control gain. This gives it a unique, program dependent compression characteristic. In addition, the all tube signal path and the transformers adds a wonderful and musical character to the sound.The ease of use with only two main controls makes it very simple to achieve the desired sound. These attributes has made the original units a favourite of engineers and musicians worldwide. This classic sound is now available at a very affordable price point with the COMP-2A.Features:Vintage style all tube signal path. The tubes are fitted with grounded shields.Transformer balanced input and output. Can drive almost any load, balanced or unbalanced.Golden Age Project's version of the classic optical unit using a long life electroluminescent panel and two carefully matched Silonex NSL5910 photoresistors for T4B-style electro-optical gain control with program dependent attack and release times.Very simple to operate with only two main controls, Gain and Peak Reduction.HF control can make the side-chain circuit more sensitive to mid and high frequency content.Linear low noise regulated filament and high voltage power supply.A big meter selectable to show gain reduction or output level at two different reference levels.Hardwire bypass switch for easy comparisons.XLR and TRS input and output jacks for flexible connections.Link jack and switch for connecting to another unit for stereo operation.All external controls located on the front panel.Compact 2RU half rack format.
