Earthworks Audio

The QTC Series (Quiet Time Coherent) is designed for recording quieter sources such as vocals, strings and distant miked orchestras or choirs. These low-noise omnis are also an excellent choice for drum overheads, close-miked wind and percussion instruments. Earthworks’ reputation for realism is based on these distinctive omnis. Time Coherent Response means these models do not smear the time domain as most microphones do.With a frequency response to 40kHz and excellent impulse response, it will reproduce sounds with incredible detail that are true and life-like, making it an ideal and affordable choice for recording applicationsPerfect for recording the accuracy and full detail of instruments in the studio yet robust and subtle enough to record bird sounds in the jungleIntended for detailed sourcesOmnidirectional polar patternFlat frequency response, fast impulse response and exceptional polar characteristicsAccurate and uncoloredHandles sound levels up to 142dB with no proximity effect or handling noiseRequires 48V Phantom Power

Matched pair, includes wooden box. Earthworks cardioid microphones are unlike all the rest, as they have patented near-perfect cardioid patterns. The sound across the entire front hemisphere is remarkably uniform and is flatter at 90 degrees than most microphones are on-axis. This results in uncolored off-axis rejection for recording and greater gain before feedback for live sound. They effortlessly handle up to 145dB SPL while simultaneously revealing subtle details that other microphones mask. All SR models are a superb value and will provide excellent results for both live performance and recording applications. While the SR25 was engineered to be used in their DrumKit System, it can also provide stunning results on a wide variety of instruments and vocals.The SR25 has the same attributes as the SR30 except its high frequency response extends to 25kHz. It will handle up to 145 dB SPL, is smaller in size, weighs less and costs less than the SR30. The performance vs. price ratio of this microphone is excellent. Specifications  Frequency Response: 50Hz to 25kHz Polar pattern: Cardioid Sensitivity: 10mV/Pa (-40dBV/Pa) Power requirements: 48V Phantom, 10mA  Peak acoustic input: 145dB SPL  Output: XLR (pin 2+) Minimum output load: 600 ohm between pins 2 & 3 Noise: 22dB SPL equivalent (A weighted)  Dimensions: 6.5"L x 0.86"D  Weight: 5.64 oz.

The TC20 (same as SRO) is our least expensive general-purpose omni with high frequency response to 20kHz. Its sound and performance is similar to the TC30 or TC25 and covers the same range of applications. For live sound the TC20 can be used for close miking instrument amps, drums or brass. A TC20 under the strings of a standup bass or inside a kick drum will produce amazing sound. A pair of TC20s connected to a stereo recorder will provide great results for recording rehearsals and performances. The TC20 is great for general studio use and is an exceptional value.

The Quiet Time Coherent QTC30 has an excellent cost/performance ratio. With a frequency response to 30kHz and excellent impulse response, it will reproduce sounds with incredible details that are true and life-like, making it an ideal and affordable choice for recording applications. Its small stainless steel body is 6.5 inches long and has no handling noise. The QTC 30 is an extraordinarily accurate microphone. It provides that famous Earthworks Sound with lower self noise than was thought possible with such a small a diaphragm. The QTC30 delivers flat, extended Time Coherent response from below 6Hz to beyond 30kHz, typically within ±0.5dB from 20Hz-20kHz. More importantly, its impulse response is faster and cleaner than any other recording microphone we have measured except our own QTC1. Its clean impulse performance allows the QTC30 to transduce wave forms exactly giving you a true and accurate representation of sonic events as they happen in the air. What this means for you is stunning, lifelike realism. It offers you the experience of being there. The QTC30 is among the best possible choices for ambient room miking but it is also exquisite for close miking of quieter more delicate sources. This microphone is a very good choice for all applications where natural, uncolored pick up of sound is the desired result. The QTC30 effortlessly captures the full size and natural texture of many difficult and complex sources ranging from Location Recording of Classical, Jazz, Ethnic, Folk and Pop music to Percussion, Piano, Guitar, Upright Bass, Strings, Vocals, Brass, and Woodwinds.It is also useful for those applications when you want to capture natural sounds with the feeling of reality intact, like Sound Effect, Foley, ADR, Sampling, Birdsong and even the subsonic calls of elephants. If you prefer transparency over coloration, a matched pair of QTC30s is a 'must have'. Listen! You can hear all of the sound with the QTC30. It sounds like you are there. This is the microphone of your dreams! Specifications Frequency response on axis: 6 Hz to 30kHz Polar pattern: Omnidirectional Sensitivity: 30mV/Pa (-30.5dBV/Pa) Power requirements: 48V Phantom, 10mA Max acoustic input: 142db SPL Peak output voltage: 10V Output: XLR intended to drive a balanced input (Pin 2+) Min output load: 600 ohms between pins 2 and 3 Noise: 22dB SPL (A weighted); 24.5dB SPL (Unweighted) Dimensions (L x D): 160mm x 22mm (6.25 x .860 inches) Weight: 225g (.5lb)

The TC25 was engineered to be used in the Earthworks Drumkit System, but can also provide stunning results on a wide variety of instruments and vocals. The TC25 has the same attributes as the TC30 except its high frequency response goes to 25kHz. It will handle up to 145 dB SPL, is smaller in size, weighs less, and costs less than the TC30. The performance vs. price ratio of this microphone is excellent.   Specifications Frequency Response: 9Hz to 25kHz +1/-3dB Polar Pattern: Omnidirectional Sensitivity: 8mV/Pa Power Requirements: 48V Phantom, 10mA Peak Acoustic Input: 145 dB SPL Output: XLR (Pin 2+) Min Output Load: 600 between pins 2&3 Noise: 27dB SPL equivalent (A weighted) Dimensions (L x D): 6.5" x 0.860" Weight: 0.35 lbs

The SR25 is designed specifically for drums and percussion and is the model that comes in the Earthworks Drumkit™ System. The SR25 has a brilliance that is ideal for drum overheads, percussion, Leslie, guitar and bass. Alone or in combination with Earthworks KickPad™ it is perfect for kick drum. The SR25 is a versatile microphone for general studio and stage use. Its uniform pickup pattern results in remarkably open sound, while excellent off-axis rejection reduces feedback and maximizes available gain.A mounting clip is included with the microphone. This microphone has no removable parts.Earthworks SR25 is a directional prepolari-zed condenser microphone with a first-order cardioid pickup pattern directly coupled to a dedicated wideband, low output impedance transformerless preamplifier. The SR25 requires a standard 48V Phantom Power supply. It features a flat frequency response from 50Hz to 25kHz, fast impulse response, very low handling noise, uniform polar pattern, and high SPL handling capabilities. It provides excellent uncolored rejection of sounds arriving off-axis.Earthworks SR25 is easy to operate. Connect the microphone to a microphone preamplifier supplying 48V phantom power using a standard XLR microphone cable. Please allow up to one minute for the microphone to settle. Plugging in the microphone “hot” (phantom power already present at the input) will not damage the microphone, and is actually preferred for faster settling. It is normal for any phantom powered mic to “pop” when plugged in or powered up. Make sure to mute the signal to speakers or headphones when phantom power is first applied.

The SR30/HC (same as SR78) offers exceptional directional performance for guitar, sax, flute, drums, bass, and vocals. It is ideal for natural sound combined with more off-axis rejection, or to reduce unwanted room sound. It can pick an acoustic instrument, like a guitar, out of an ensemble while still sounding detailed and life-like. It is a powerful tool for broadcast and vocal production applications because its clarity and detail enhances verbal communication. For open, uncolored clarity combined with off-axis uncolored rejection, try an SR30/HC and listen to what it doesn’t pick up.

The SR30 (same as SR77) is a remarkable cardioid that maintains most of the characteristics of our omni microphones. At 6 inches away from the source it sounds as onmi-like as a cardioid can. The off-axis rejection is substantial yet uncolored. Its impulse response is very fast and smooth and the sound stays the same across the entire front hemisphere of pickup. In the studio or on the stage, the SR30 is an ideal choice for a variety of acoustic instruments including sax, flute, trumpet, guitar, piano and drums. It is superior for choir because it doesn't spotlight; rather it picks up an entire section or area with no hot spots. The SR30 is popular among concert tapers because of its open uncolored sound and among jazz enthusiasts for its ability to capture explosive performances while retaining the subtle nuances of artist.Specifications Frequency Response: 30Hz to 30kHz Polar pattern: Cardioid Sensitivity: 10mV/Pa (-40dBV/Pa) Power requirements: 48V Phantom, 10mA Peak acoustic input: 145dB SPL Output: XLR (pin 2+) Minimum output load: 600 ohm between pins 2 & 3 Noise: 22dB SPL equivalent (A weighted) Dimensions: 8.4"L x 0.86"D Weight: 7.94 oz.

Many have told us that there needed to be a better way to mike a piano for churches, performing arts centers and recording studios. The new Earthworks PianoMic System meets all of these needs: Incredible High Definition Audio that will outperform any microphones at any price. Cannot be seen from outside of the piano (needs no stands or mic booms) Superb sound with the piano lid either up or down Virtually no leakage from sounds outside the piano Incredible gain before feedback Recording studios can now record piano with other instruments in the same room Quick, Simple and Easy Setup It all started when sound contractors informed us that they had tried all types of microphones and microphone pickup systems for pianos in churches. They didnΆt like the sound they were getting, they didnΆt like the microphone stands in front of the piano, they couldnΆt get enough sound level before feedback and they were also getting leakage from nearby instruments into the piano microphones. In addition, engineers in recording studios told us how difficult it was to record an acoustic piano in the same room with other instruments. When we let churches and recording studios take the PianoMic prototype for a test drive they were amazed and said it was an absolute winner, hands down! If you have a piano in a church, performing arts center or in a recording studio you too will be amazed when you see and hear the new Earthworks PianoMic™ System featuring Random Incidence High Definition Microphones. For recording studios the PianoMic™ System is a dream. You will never again have to spend the time and effort to mike a piano with stands and booms. Just place the PianoMic™ System inside the piano, position the two microphone heads where you want them and you are done. Anytime you want to record the piano, just plug the PianoMic™ System into your mic inputs and you are ready. Never again will recording engineers have to go to great lengths to record an acoustic piano in the same room with other instruments. Historically, they have had to place microphone booms inside the piano, close the piano lid (leaving room for the mic stand booms) then cover the piano and the openings around the mic booms with heavy moving blankets. It is a nightmare. With the PianoMic™ System, you simply close the piano lid (which will now close all the way because there are no mic booms) and you are in business. Leakage is insignificant, and if thatΆs not good enough, you can now very easily cover the piano with a moving blanket (without having to work around microphone stands and mic booms). Recording studio engineers who have seen and used the PianoMic™ System say the PianoMic is incredible! We took the PianoMic™ System into a church that was having piano sound problems: (1) they couldnΆt use the piano along with the organ, because the piano microphone went into feedback; (2) they were having problems with leakage from instruments in the orchestra into the piano microphone; (3) they could not get the piano loud enough in the choir monitors without running into feedback; (4) they could not hear the full range of the piano (low, mid and high strings) evenly; and (5) they were not happy with the overall quality of the piano sound in the sound system. When they tried the PianoMic™ System they obtained an incredible piano sound and could hear the full range of the piano including the high and low strings. They could now make the piano louder than the organ (without feedback). The choir members were now telling them to turn down the piano in the choir monitors and orchestra instrument leakage into the piano microphones was no longer a problem. The Earthworks® PianoMic™ System overcame every problem they were encountering with their piano sound. The Earthworks® PianoMic™ High Definition Microphones™ do remarkable things with the sound of a piano. You will hear fidelity and detail like never before. Acoustic feedback is no longer a problem. You can have all of the sound level you want and even more, all you will hear is the pristine sound of the piano. Better yet, there are no visible microphone stands or mic booms in front of the piano. All you see is the piano just like it is in the adjacent photo of a performing arts center while you enjoy its magnificent sound. The PianoMic™ System is also ideal for use in touring sound systems as it is easy to transport, easy to position and it will provide the same pristine sound quality every time. The Earthworks PianoMic™ System is a long-awaited, incredible product for performing arts centers. The PianoMic™ System has it all!
