Hey everybody. I'm a long time lurker on this board and now need some input from you guys.


I recently purchased the Onkyo HT-S7100 Home Theater In a Box and I currently think I may have a defective surround sound processor. I just need some of your opinions to see if I missed anything.


Here's my problem: any signal from any idividual surround sound speaker is blended in all four surround sound speakers (on any surround listening mode). I have properly setup all speakers with the Odyssey calibration tool and all speakers output to their respective locations from the receiver. I can even check it back with the Receiver's pink noise under Menu 2.4 Level Calibration and everything work as it is supposed to here.


The problem occurs when I use a test DVD like Digital Video Essentials and cycle pink noise to all 7 speakers and subwoofer. Everything goes fine with the Left, Center, and Right speakers but by the time it gets to Surround Right and Surround Left, the pink noise comes from all four surround speakers. The Surround Back Right and Left signal does the same thing but with the Surround Back speakers a lot louder than everything else.


I don't know if I have something setup wrong here. My DVD player is connected digitally with a coax cable. The receiver DD light is on and DPLIIx mode on. I've also tried DTS Neo6 and it does the same exact thing. I've also tried a different DVD with THX Optimizer and the problem still occurs. From what I've read here and on other sites, setting the DVD player to output in Dolby Digital and/or PCM souldn't make a difference (should it? I didn't try).


Is there anything else I should check before I give a call to Onkyo technical support? I can't think of anything else right now.


I also have a Dish Vip722 hooked up with HDMI but have no way to test for proper surround signal on this (with dedicated pink noise to each speakers). I could have a defective DVD player also.


What are your thoughts?

You probably have analog set to PLIIx for that audio input. So it will cause the analog signal to mix to all the speakers. I am not at home, so without the menu in front of me, I think you'd want the setting stereo or something like that.

Like itsloud mentioned it sounds like your applying DPLIIx to your incoming digital signal (DD/DTS). Turn it off and run straight DD/DTS.

Thanks. I'm trying to figure out what I have set wrong from what you guys are saying.


So should I change my Listening Mode Presets (Menu 5.x)? I have all of them set to Dolby PLIIx right now (when available). I thought this setting was just to tell the receiver at what Listening Mode it should default to when it would start receiving a specific signal. What would guys recommend?


Also, according to Dolby, the Dolby Pro Logic IIx processing is compatible with Dolby Digital, Dolby Digital EX, DTS, DTS EX, etc. That would be why I had it set to DPLIIx on all of them. Shouldn't the pink noise pan seemlessly from one speaker to the next, even with DPLIIx on with the DD signal?

I found out what was wrong with my setting. The receiver was setup right. My DVD player had its Dolby Digital and DTS mode set to OFF. I was only getting regular stereo out of the digital coax, I never thought I would get any sound out of the digital connection unless it was DD or DTS, I obviously assumed wrong.
