Two independent signals
Mono
Analogue 1 and Analogue 2 are used as separate audio channels.
Analogue mode (XLR)
In Analogue mode, the TX processes the two balanced XLR/TRS mic/line inputs as 2 × mono, mono sum or 1 × stereo.
One summed mono signal
Mono sum
Analogue 1 and Analogue 2 are combined into one mono source.
One stereo signal
Stereo
Analogue 1 carries the left channel and Analogue 2 carries the right channel.
