Mic Inputs

The XLR 3 pin sockets used for the microphone are electronically balanced. They have the
following connections:
Pin 1: Screen
Pin 2: Phase
Pin 3: Non-phase

Input Gain

Recessed pre-set potentiometers allow for adjustment of the gain of the microphone
inputs. This provides a gain range of 36dB to 75dB which enables the use of dynamic and
powered microphones. Connect the mic input and adjust the gain until the line output is at
the level that you need.
