So I decided yesterday when I hooked up my new DVD player to try using auto MCACC with the microphone to set everything up. I have a Pioneer VSX-1015TX receiver and 7 JBL speakers with no subwoofer just yet. Anyway, I used the microphone and played a DVD in my new Sony DVD Player and it was fantastic, the sound was noticeably better. Where before when I wanted to listen to a great scene really loud I would jack the volume up to +3 or +5, now it's almost too loud to listen to at -8 to -5, I can't think of any reason to ever go up above 0. But when I switched back to my satellite tuner I heard a problem. For some reason it seems that the only speaker working in the TV/SAT mode is the front left speaker. In DVD mode they're all working fantastically, but when I try to watch TV it seems like it's all coming from just that speaker. To test it out I disconnected the speaker wire from the back of that speaker and turned the receiver back on, there is sound coming from the other speakers but it is SO much quieter it might as well not even be there. With the front left speaker connected I can sit on the couch and set the volume at -25 and hear just fine, when I disconnected it I had to turn it up to +5 to be able to listen from all the other speakers. Now I don't know what the heck could be causing this because when I switch to the DVD player everything works perfectly. And it was working fine when I set it up by hand. I'm using the sound mode "TV Surround" to watch TV and using "PLII +THX" to listen to DVDs, but even switching to other sound modes it still all comes out of the one speaker when I'm trying to watch the satellite. My theory as to what happened might be right, but I have no idea how to fix it. When I put the new DVD player in I switched from RCA to Digital Opitcal for audio using a monster cable Ultra 1000 fiber optic audio cable. I plugged that into the top digital audio in slot in the back of my receiever and then I had to go into the setup and change the input assign for that digital in. But I'm still using RCA to connect my satellite. The only thing that changed was that cable, so I have to assume that broke it somehow. Anyway, if anyone has any suggestions that would be great. Also I checked the distance and input levels in manual MCACC and they weren't ridiculously out of proportion to the point where it would cause a 25-30db difference. Hopefully it's just a simple setting that needs to be changed. If anyone knows what might be going on I'd love some help. Thanks!
