Hooked this amp up and man what a difference, it really improved the sound quality of our pa system, gives you plenty of headroom without driving the system , very clear low end, and High's You can hear the fan , but it doesn't effect sound quality. So far we like this amp, it is a winner.
Amp is fine so far but the documentation is deplorable. There's NOTHING in the manual or anywhere online about how about how to run it in mono bridged mode.
