input gain for each input. The gain is adjusted by rotating the screw and the adjustment range is from mute (fully counterclockwise) to +20 dB (fully clockwise). See the note below.

Unity gain (0 dB) for each input channel is around the 12 o’clock (vertical) position with the potentiometer adjustment screws vertically aligned with the indicator dots, as shown here:

The potentiometers of the MIX 301 are set precisely to unity gain at the factory. Once an adjustment screw is turned, test equipment will be required to accurately reset the potentiometer to unity gain.
