Re: Audyssey MultEQ: Questions and Answers - Onkyo, Denon, et. al.
Plochner,I am not an expert by any means. However, it sounds as if you have either one of two possible problems. First; the hiss could be electrical interference from another electrical device's power. Turn on the amp and set the system up to where you can hear this hissing sound. Then start unpluging different components that are in the area (Game consoles, TV, Cable Box, Wifi router, ect...) or plugged into the same power socket. As you unplug each componenet see if you note a reduction in the hiss.
If that does not work. Try running an extension cord from an entirely different power source to the Amp. This will help isolate the AMPs power.
If that don't work double check the Bass and treble settings menu in the AMP and check to see if the treble is not cranked up too high.
Did you set all your speakers to Small or crossover to 80Hz or higher.
Good luck with resolving your problem.
