The AOS is a dedicated no compromise fully adjustable moving coil pre-amplifier using a circuit design based heavily on Rega's award-winning AURA reference MC phono stage. Housed in a custom made half width case, the AOS delivers exceptional definition and greater realism to all your recordings, bringing your favourite vinyl to life. Designed to work with a wide range of moving coil cartridges, it has plenty of gain for low output MC’s and excellent load adjustability making it the perfect partner for whichever Moving Coil you are using.
The Aos is a two stage “all analogue amplifier” with no digital control circuitry. The fully aluminium case screens the internal circuit from any stray RFI signals. Rega's designers have avoided including any unnecessary components or circuits that may degrade the signal path. The AOS incorporates many innovative design ideas including a self-adjusting servo control which compensates for any variations in ambient or operating temperature.
The AOS utilises 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 4300 pF. The input sensitivity can be changed by 6 dB via the back panel. An automatic standby feature has also been added which puts the unit to sleep after a period of no signal. This can be deactivated via dip switches located on the rear panel.
