The amplifier is a differential amplifier. So it amplifies the difference between A and A-.
In case of mono, you hear theretically nothing. Small differences between A and A- are amplfied. In case you have mono with counterfase signals, this results in a ver good loud audio.
When A and A- are stereo, your loudspeaker will give the difference betwwe L and R.

Thanks Volhout, this is what I thought, but doesn't match the observation that when fed a stereo signal with the same signal on L/AIN+ and R/AIN- I am getting a reasonable output. I guess I need to check my wiring.
Best wishes,
