Module Layout

The A-138pv Performance Mixer Input provides four identical input channels. At the top we find the input jack with a level LED, but the gain control for adjusting the signal levels is located at the bottom, right next to the mute switch
,
for practical reasons,
and below the input is a potentiometer that adjusts the aux send level
.
For each channel you can use jumpers to set whether the aux is pre- or post-fader.

The next potentiometer determines the panorama position of the respective channel and below it there is a larger potentiometer which determines the output level.
