So i hooked up my new 5760 last night. After installing one for my Father In Law last weekend I was so stoked. Previously, I was running a Kenwood VR3080 with a 5.1 setup. All wiring was pulled thru the wall during house construction and I checked with ohm meter for continuity. I had my 2 surrounds hooked at the back surround location while waiting for the 7.1 upgrade. Ok, don't laugh, but here's my mish mash of speakers. I'm almost embarassed to post it but I had to get speakers that had high WAF else, I be killed. Yammy HTR 5760 Liteon LVD-2001 DVD player Dish 501 PVR Older Kenwood 5-cd changer JVC Hi-fi VCR (older) Speakers: All 8 ohms Fluance ES-1 mains DCM Center (2- 6" mids) JBL PSW1200 12" powered sub Klipsch Quintet surrounds Cambridge Soundworks The Surround Dipole/Bipole back surrounds As I said, the Klipsch were hooked in the back surround locations and worked fine with the kenwood. I put the cambridge in their place and moved the klipch to the side surround. All connections to the speaker are 5 way binding post plates with wire going from plate to speaker. Long setup, sorry. Now, I started the autosetup. Every channel was fine until it hits the back surround left channel. When it plays a high volume tone, it trips protection. I did this twice. So I do manual and the left surround and left back surround both trip the protection. The strange thing is that at lower volume all speakers work fine, even test tones. Could it still be a short? LIke at higher volumes, more current is passed and that trips the circuit? It's totally possible since I had to make new cables for the new speakers that I might have a short. But, I thought that it would instantly trip the circuit but I guess only at high volume/current. Have I assumed correctly or could this be a prob with the receiver?
