Serious Problems W/my Dolby Pro-Logic Signal

[akrauss]

I have been enjoying my current HT System for many years and all of a sudden (about 1 month ago), I began experiencing a most disconcerting problem : When my receiver is set to Dolby pro-logic, the signal coming from my left main speaker intermittently develops a static like interference that is most pronounced. I have checked the cable to the speaker which seems fine. I did not check all the cables b/c the problem does not appear when utilizing the dolly digital signal (thru my satellite box and DVD player). Likewise, if I switch off all effects, so I get a stereo signal, it sounds fine. Thus, since the same cables are being used in all scenarios, I assume it cant be a cable problem. The only 2 things I can think of would be 1) My receivers prologic processing has gone caput; or 2) The signal from Dish Network is faulty (my hope). I have not yet contacted DISH. FYI : Among other items, I have a Yamaha RXV-9020 receiver, Paradigm Reference 60 speakers (L & R) and a DISH receiver (model # escapes me). ANY HELP WOULD BE MOST APPRECIATED.:shrug:

I have no problems with DPL through my Harman Kardon receiver, so I'd say that your Yamaha may be to blame here. Can you force your DVD audio into DPL to test?

BTW, welcome to DBSTalk akrauss! :hi:

That's what I'd try. Connect your DVD player the same way the sat receiver is to the same inputs and play a music CD (same audio type as the DISH audio). See what happens!
