![]() ![]() Are they the cheap type, or quality one?Īnd last, a recommendation that sometime work with cable that are not well insulated, like an RG6 coax cable that is. ![]() While you said you try some different cables. Or something new, if also more difficult to pin point the problem? If both are previous pieces of equipment, did you always had did problem. If both, a lot more difficult to diagnose If the Sub, than it could be the Amp plate. If a new AVR, it could be a defect in the sub output. I did not wire up the brown ground wires coming off it, but I did briefly touch them against the sub chassis as a test and it did nothing.Ĭlick to expand.I few more questions for youĭid you got a new AVR, Sub or both are new? I put it between the sub and AVR (really not anywhere else it could go in this signal chain). > Which isolator did you try and where in the signal chain was it placed? ![]() Hmm this actually makes a noticeable difference. > If you use a cheater plug on the sub plug does the hum stop? If I run the sub off the HT circuit I get hum on the DJ setup. If I run the sub on the DJ circuit I get hum on the HT. This won't work for me because I have two sources that I'm switching between (DJ setup and HT). Running sub and AVR off the same circuit stops the hum. > If you unplug the cable/satellite cable from the wall does the hum stop?Ĭable satellite / cable? Not sure what this is. ![]() If I unplug the RCA into the sub the hum stops. >If you unplug the sub rca from the AVR does the hum stop? What speakers are you hearing the hum on? ![]()
