YK Thom Posted February 22, 2016 Share Posted February 22, 2016 I have noticed that I get a loud pop sound ( a single pop),from my center channel when I turn my system on. Any thoughts on what may be causing this? None of the other speakers do this and it doesn't happen when I shut it down. This is a pretty recent thing.

CECAA850 Posted February 22, 2016 Share Posted February 22, 2016 Receiver or amp and pre-pro? Quote Link to comment Share on other sites More sharing options...
YK Thom Posted February 22, 2016 Author Share Posted February 22, 2016 (edited) It is a Marantz SR5008 AVR (7.2 but configured as a 5.1). For television viewing I most often have the sound setting on Auto. Edited February 22, 2016 by YK Thom Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted February 22, 2016 Share Posted February 22, 2016 Swap the center channel speaker wire at the with either the LF or RF speaker and see which one pops when you power it up. If it moves the problem is in the receiver. 1 Quote Link to comment Share on other sites More sharing options...
ClintonH Posted February 22, 2016 Share Posted February 22, 2016 I had the opposite happening, pop on my pro amps (for subs) when I shut down. I traced it back to my Cable PVR. Ended up running a grounding wire from it to my AVR and a isolator on my coaxial cable. I believe it was the isolator that fixed it for me. But it could be a lot of things just have to go through the elimination process. Quote Link to comment Share on other sites More sharing options...
YK Thom Posted February 23, 2016 Author Share Posted February 23, 2016 Have notice that if I turn on the unit in stereo mode there is no pop. Once I switch to 5 channel while it is on, no pop. Quote Link to comment Share on other sites More sharing options...
