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 ).
