Rega Aria MK3 MM and MC Phono Stage Amplifier

Description

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.

Note: All Aria MK3 MC
settings will be factory preset for all Rega MC cartridge
models. See Specifications tab for more information.

Technology

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.

MC Stage Design & Features

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.

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.
