XOT

Mix System Master Channel

XOT is the master module of the CATOFF MIX modular mixer. It sums the incoming signals from the XINs input channels and controls master volume. XOT can be connected to an amplifier, headphones, and an external effects or monitoring system. XOT contains send and receive sockets with the adjusting input and output level controls for each of the two AUX buses. There are three different audio outputs, analog VU meter and master mix volume control. XOT is a non-independent module! One or more XIN is required (sold separately or as a part of Complete Set). No standalone use and not sold separately
