Rega

DescriptionThe Rega Fono Mini A2D-V2 is a high quality phono pre-amplifier for use with any moving magnet cartridge. The addition of USB interface allows you to easily transfer vinyl to your PC. The Fono Mini A2D-V2 is designed to amplify the signal from a moving magnet cartridge to a suitable level for all line level inputs of an audio amplifier. The new Fono Mini A2D-V2 benefits from an extruded aluminium case and very user friendly front and back panels that make this phono pre-amplifier a very easy product to use.

DescriptionThe Rega Fono MC disk stage is designed to amplify the signal from a moving coil cartridge to a level which can feed into a 200mV line level input on a standard hi-fi amplifier.

The Fono MM MK5 phono stage has been designed to be effective, easy to use and above all, to reproduce music. The Fono MM MK5 uses a fully discrete, cascaded, complementary amplifier input stage, a configuration designed to optimise the performance of your moving magnet cartridge. Now housed in a brand new redesigned case to match the new Fono MC and Rega’s latest range of electronic components offering a modern look guaranteed to integrate in to any hi-fi system.The perfect partnerThe aesthetic design of the Fono MM was as important as the quality of its electrical capabilities, so it benefits from the same updated aluminium case as the Rega Neo and Fono MC amplifier, giving it a design which offers a familiar feel and moreover brings it in line with its illustrious bigger brothers. The RIAA equalization has been split into two stages to minimise interaction. Polyester capacitors have been used in the signal path and polypropylene capacitors are used in the RIAA equalization circuits.

The reference Aura MC stage is the culmination of decades of electronic design development. We have created the ultimate, fully adjustable, three-stage, all symmetrical pre-amplifier designed purely to extract the very best performance from your moving coil cartridge and vinyl playback system. Design Innovation Built into a completely re-designed custom case, the Aura is dedicated to moving coil cartridges and stays clear of any compromises. We have avoided including any superfluous functions as they obstruct the signal path and degrade the sound quality. The Aura phono pre-amp incorporates remarkable and innovative design ideas. If you are a vinyl connoisseur, then the Aura MC is an absolute must for demonstration. First Stage The first stage is a symmetrical, complementary class A amplifier, using parallel connected Linear Systems ultra-low noise FET (Field Effect Transistor) transistors configured as a symmetrical compound pair input stage. The use of FET transistors ensures there is no bias current flowing in the cartridge coil so as not to upset the delicate magnetic geometry of the cartridge. The input circuit configuration also alleviates the use of any coupling components between the cartridge output and the input stage FET transistors, which would degrade the sound. The complementary ultra-low noise FET transistors are carefully graded and matched for optimum performance. This stage drives the passive high-frequency part of the RIAA equalisation stage. Second Stage  The second stage is a symmetrical, class A, differential amplifier with a common base driver stage; this is also used as the active amplifier in the low-frequency part of the RIAA equalisation stage. Third Stage The third stage inverts the signal to provide the balanced output along with the output of the second stage; the third stage uses the same circuit topology as used in the second stage. The power supply is a symmetrical, discrete tracking power supply using fast diodes and a low noise voltage reference. Each stage has its own localised power supply and LED referenced current generators. To maximise headroom, the Aura has a power supply voltage, which is 60% higher than normally found in such a pre-amplifier. Very high quality, polypropylene capacitors have been used in the signal path. 1% tolerance polypropylene capacitors are used in the RIAA EQ stages and audio grade capacitors are used in the rest of the circuit. Gain, Mute and Mono switching is implemented using high-quality relays.

ARIA MK3 MM/MC Housed within our latest half width custom designed case to give it a fresh new look and match the range are two entirely separate, high performance phono stages. One fully adjustable, dedicated moving coil and one moving magnet. Each stage is designed and engineered to maximise the potential of your vinyl system whilst remaining easy to use and set up. The Aria is an “all analogue amplifier” with no digital control circuitry. The fully aluminium case screens the internal circuit from any stray RFI signals. Our designers have avoided including any superfluous gadgets as they obstruct the signal path and degrade the sound quality. The Aria incorporates many innovative design ideas including a self-adjusting servo control to keep the MC input circuit at its optimum, compensating for any variations in ambient or operating temperature. Both stages have their own separate input sockets and input pre-amplifier circuitry. This enabled us to design bespoke input circuitry for each cartridge type without compromise. Signal switching is performed at high level and low impedance (via relays) ensuring there is no degradation of the signal. Key Features High performance switchable MC & MM stage Fully adjustable MC stage MC input uses parallel connected low noise FET's MM input uses low noise bipolar transistors Custom designed case All analogue amplifier Bespoke input circuitry for MM & MC Lifetime warranty against manufacture defects MM Stage design & features The MM input uses low noise, bipolar input transistors also configured as a compound pair. There are two separate power supplies for each channel and further sub-power supplies for each of the low noise input circuits. Nichicon FG electrolytic capacitors have been used in critical positions throughout the power supplies. Polypropylene capacitors have been used in the signal path and equalization networks. Discrete circuitry is used throughout the signal path ensuring full control of the circuit design. MC Stage Design & Features The MC input uses parallel connected, low noise FETs (Field Effect Transistors) configured as a compound pair. The use of FET transistors ensures there is no bias current flowing in the cartridge coil so as not to upset the delicate magnetic geometry of the cartridge. The MC input has the provision for selecting resistive input loading of 70 Ω to 400 Ω and capacitive loading of 1000 pF to 4200 pF. The input sensitivity can be changed by 6 dB via the back panel.
