Hi, I Need Help! All of a sudden I have been getting noise and,,,

Tech Square

Technical and speculative discussion of amps, cables and other topics.

hum through the speakers when I turn my amps on, but it goes away when I then turn on the pre-amp and electronic crossover. I know the pre-amp should be turned on before the amps. Before this noise started I would not get any electrical noise or hum when turning on the amplifiers first. I just cleaned the crossover switches and RCA inputs with Caig Deoxit, but it didn't help. This system has 3 power amps. I appreciate any tips and advice, thank you!
