buzzing ????

[tsalter9]

I have a question maybe someone can shed some light on , I have a buzzing coming through my all of my speakers , three inside , front left and right and center , when I pause the dvr or cd player it keeps on going for about 2 seconds then stops , when I mute it , it does not make the noise for that 2 seconds , I swapped out a couple of rca's to see if maybe for some reason it was all three of them , didn't stop , anybody got any ideas?

Does the issue persist if your TV is not powered on...say listening to audio from your CD player with the TV and DVR powered off?

Do these one step at a time and see if it happens.
1. Remove the power conditioner
2. Disconnect the cable box.
If that doesn't work.

-Disconnect everything from the amp EVERYTHING except the power cables and a single speaker cable. Try.

Then add on one at a time and try .

one more RCA cable. Connect it to your DVD player.

Swap the working RCA cable with each channel one by one.
Finally add all speaker cables one at a time. Then finally add on everything else.
Whenever you get the buzz stop and tell us at which point the buzz appeared.

Whenever you get the buzz stop and tell us at which point the buzz appeared. This is very good advice.  I have revealing speakers, (101 db +) and when I first set them up, there was terrible hissing and ground noise.  At one point,  I measured nearly 50 DB from 1m!  After lots of swapping, unplugging, wiring new circuits, isolating, re-racking, cable management, and sweat, I have a dead quiet and ultra-dynamic system that has turned me into a music lover again.  Among the most significant changes I made: 1) a proper rack for equipment (Turns out, separating powerful components with space can be audible.); 2) a single dedicated circuit with isolated ground for the whole everything.  (Turns out ground noise is ameliorated with a better ground!) ; and 3) ... well, I've found no #3.  I feel like I've tried everything though: RCA caps, fancy cables, various isolation tweaks, special PC power supplies, a 100% solid state PC, etc.  The latest were the Pangea AC-14Se power cables for "better transient response" and "lower noise floor."  Maybe that all works for others, but for me most significant were #1 and #2 -- big changes to infrastructure.  I'd like find ways to measure the effects of tinkering about the edges, but if I hear nothing, back it goes, and I figure if there ever was something to be heard, then it would come though such efficient monitors.   So, at this point, rather than acquire more audiophile stuff, I just get good wine and listen.

Hi your speakers look to be very interesting. Do you have a picture of your mains?
