Channel 1 Mic amp with D.I.:

The features of the microphone amplifier consist of low noise and low distortion. It offers switched gain controls for high accuracy level setting (4 dB steps), D.I. Input (high impedance), level indication, high pass filter (switchable), 26dB pads (switchable), phase reversal and 48v phantom supply (switchable).

Mic amp can be linked to Limiter / Compressor [ Switchable ]

Channel 2 Limiter / Compressor:
Low noise and distortion [Decca 1977 circuit brought up to date]
Recovery time switched, 1secs and 0.3secs
Threshold calibrated in dBu ref. output level
LED metering
Limiter/compress On/off switch
Overall low noise and distortion.
Input gain control to +20dB
