Aria
MM
and MC Phono Stage
Design
Housed within our latest half width custom designed case 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.
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 70W
to 400W
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.
