The unit did add a barely perceptible amount of noise to the total system. When I say ‘barely perceptible’, I mean that it was difficult tell the difference over the building’s/existing system’s noise floor (I did the install at 11:00 pm and was the only one there), not audible at all during Sunday morning.

The hiss from this unit is very audible IMO. Perhaps not if your HVAC is noisy. I have 2 units here, they both hiss. This seems to be inherent. I can mute the outputs and inputs, hiss is still there. Unplug the unit from the amp, no hiss. This is with the amp gains at 12 oclock. Unit at +4. This is with the default preset. Noise is On output 1.
The other stranger noise problem is in 1 unit on config 1, with 1 2way xover, there is very low noise, low freq. intermittent sound, hard to describe, but some electronic sound produced with nothing plugged into it's input. I switched cables, speakers, unplugged all inputs, still there. Save preset come back, and it's gone. Recall original preset comes back.
I understand this is a budget unit, maybe it is ok for a club with high ambient noise, but not in churches etc. We already had one unit replaced that had a horrible buzz in it.
