Rega Phono Stages
Posted by The Sound Organisation on Oct 9th 2018
The reference Aura MC stage is the culmination of decades of electronic design development. Rega 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.
Rega Aria Phono Stage
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.
The MC input uses parallel connected, low noise FET's (Field Effect Transistor's) 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 70ohms to 400ohms and capacitive loading of 1000pF to 4200pF. The input sensitivity can be changed by 6dB via the back panel.
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.
Rega Fono MC
The Fono MC is an exceptionally high quality MC phono stage designed to maximise the potential of any MC cartridge. Although specifically to compliment the latest Rega range of moving coils you will find full adjustability for loading is available via dip switches conveniently placed on the rear panel with two different gain settings located on the back panel making the Fono MC compatible with most low output MC cartridges.
Rega Fono MM
The Fono MM is a moving magnet disc stage which has been designed to be effective, easy to use and above all reproduce music. The new surface mount board layout has been optimised to work with the latest generation of RP turntables.
This compact design, now housed in our custom case to aesthetically match the rest of the range, offers performance way beyond that expected at this price point and makes an excellent addition to any vinyl based system. The Fono MM simply connects to the line input on the amplifier and the tonearm leads and earth (if used) to the input sockets and earth terminal of the Fono MM back panel.
Winner of the WHAT HI-FI? Award 2014, 2015 & 2016 for Best phono stage.
Fono Mini A2D
The Rega Fono Mini A2D 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 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 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.
The Fono Mini A2D amplifier offers exceptional performance and incredible value for money and promises to be a valuable addition to any hi-fi set up.
