Phase Inverts the audio signal for mono inputs; inverts the left channel signal for
stereo inputs, except in the RR case (see below) – then of course it makes
sense to invert the right channel signal. The Phase button is highlighted
whenever phase inversion is active.
Cal The input level calibration value is indicated by the blue bar graph; the exact
value is displayed in dB and can be set with the rotary encoder below.
Functions for Stereo Inputs (see the screenshot above)
Mode Selector Stereo signals can be processed in the following modes:
Mono Left and right channels are attenuated by 3 dB and mixed together
LR Normal stereo mode
RL Left/right channels are swapped
LL Left signal on both channels
RR Right signal on both channels
To indicate the current mode, the corresponding button is highlighted.
