I tried different speakers first, same hum and/or hiss from drivers and tweeter. I changed source from amp to receiver only. I tried everything turned off except source powering speakers, both receiver and amp. I disconnected everything, right down the the bus bar/surge protector and powered only the power source and the speakers with the same low level hiss and hum. It can be heard up to 6 or 7 feet away when there is no actual sound being produced.
Is this maybe normal to get some sound coming from the speakers when no input is selected?
It isn't noticeable when even the lowest sounds are being produced.
Any thoughts??
