Well, not actually hmmmmmm rather hummmmmmmm
That is what i am getting from my speakers and i need some help trying to fix.
Here is the scenario. I have my audio equipment in a rack (schitt preamp, class d mono blocks, matrix-m streamer). About 4 feet away, i have my tv on the wall underneath that is a half rack with my center channel speaker on one shelf and below that is my Oppo 103. Below that (on the floor) is my a/v receiver.
Mostly I use jriver to stream music or videos to my system. Any and all files for audio work with flawlessly and have no humm (because they go directly to the audio setup).
When I stream video, I use the oppo as my renderer, connect that to my av receiver via hdmi. The av receiver powers my front and rear speakers. I send the fl & fr (via analog) signals to my stereo rack setup. This is where the problem comes in. It doesnt matter if i use the av receiver or the oppo to send those signal from (both have individual 5.1 analog outs), the fl and fr have an awful hummmmm. I have spent a ton of time trying to isolate the cause ... it is clearly the oppo that is the culprit. Unfortunately, since i use it as a renderer for video so i cant remove it from my system. Its only other use is ripping SACD's which is pretty infrequent.
I can send the digital output from the oppo to my streamer and get a clean signal out from fl and fr but that signal is 5.1 not fl and fr. In addition, its out of synch (which can likely be corrected out).
I am trying to keep this original post manageable so i am not going to include all the tests (grounding, switching plugs, isolating oppo power, different cables, etc) i have done to isolate and change things around and thought the best way to handle is throw out the request for help, see what i get and go from there.
TIA
