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. 

MC Stage Design & Features

The MC input uses 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 4200 pF. The input sensitivity can be changed by 6 dB via the back panel.
