Wall panel, 2 channel micro-mixer, MIC and RCA inputs, TALK-OVER function for PXN88

BA-MIX is a 2 channel micro-mixer which keeps the standard wall-panel format. It allows to mix a stereo unbalanced signal (2 x RCA) with a microphone signal (XLR).
The MIC input includes a 2 band EQ (BASS, TREBLE) and it can use the talkover function to override the line signal when the microphone exceeds the talkover detection threshold.
