Maximize the Potential of Your Vinyl Playback System
Housed within Rega's latest half-width custom designed case, the Aria consists of two entirely separate high performance phono stages. There is one fully adjustable dedicated moving coil stage and one moving magnet stage. Each stage is designed and engineered to maximize the potential of your vinyl playback system while remaining easy to use and set up.
All Analog Design
The Aria is a 100% analog preamp with no digital control circuitry. The fully aluminum case screens the internal circuit from any stray RFI signals. Rega's designers have avoided including any superfluous gadgets that could 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 separate inputs and input preamplifier circuitry. This enabled Rega to design proprietary input circuitry for each stage without compromise. Signal switching is performed at high level and low impedance (via relays), ensuring there is no degradation of the signal.
MC Stage Design and Features
The MC moving coil 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 70W to 400W and capacitive loading of 1000 pF to 4200 pF. The input sensitivity can be changed by 6 dB, via the back panel.
MM Stage Design and 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.
