Description
Housed in a custom made Rega half width case, the AOS will deliver exceptional definition and greater realism to all of 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.
First Stage: The first stage is a symmetrical, complementary class A amplifier, using Linear Systems ultra-low noise FET (Field Effect Transistor) transistors. 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 input circuit configuration also alleviates the use of any coupling components between the cartridge output and the input stage FET transistors, which would degrade the sound. The complementary ultra-low noise FET transistors are carefully graded and matched for optimum performance.
This stage drives the passive high-frequency part of the RIAA equalisation stage. The complementary ultra-low noise FET transistors are carefully graded and matched for optimum performance. This stage drives the passive high-frequency part of the RIAA equalisation stage.
Second Stage: The second stage is a symmetrical, class A, differential amplifier with a common base driver stage; this is also used as the active amplifier in the low-frequency part of the RIAA equalisation stage.
