Is there a global setting in BIAB that will temporarily output all tracks, both MIDI and Real, in mono? This will be a periodic setting so changing each song is not desirable.

From the laptop audio jack, a stereo cable plugs into the L/R input channels on the mixer. From the mixer, only one speaker is to be used. A TRS cable runs from the L (mono) output on the mixer to the speaker.

I don't understand what the L (mono)on the mixer means. Does it sum any stereo signal into the one output?

I figure the sure solution is to make sure the BIAB signal from the laptop is mono. Am I thinking correctly or is it overkill?

Thanks for any help
