Hello all...sorry for the length of this post, but I'm really aggravated and I wanted to show that I've covered all the bases (anyway, I THINK I have).
This is my first new setup in about ten years so I might be behind the times a bit so I appreciate any suggestions anyone may have.
I've searched the forum and the web and can't find an answer to this problem and I'm about ready to get rid of everything.
Purchased an H/K DPR-1005 back in November and had only front and center speakers (JBL) hooked up while I searched for a full 5.1 (maybe 7.1) setup.
Purchased the Surroundbar (and PSW10 subwoofer) last month - got it home and quickly found a problem. Hooked it up and configured it per the instructions...sounded FANTASTIC...until I selected a mode (any mode) that used the surround speakers.
Terrible hiss...like white noise...even with the volume turned almost all the way down. Sounds like rain...didn't get louder when the volume was turned up but was already pretty loud. Really noticeable in DTS mode (Saving Private Ryan, Apollo 13, etc.) during some quiet scenes but was still loud in any mode that utilized the surround speakers. (Note that when testing DTS mode, I used a DTS DVD player, optical cable, set to DTS/bitstream mode with DTS turned on and a DTS version of the DVD. Just making sure that everyone understands that this isn't due to having anything mismatched though I did try out every possible combination.)
Called Polk Tech Support to verify that it couldn't possibly be the speakers...they said "no", nothing in the SurroundBar could be causing the hiss.
Okay...RMA'd the receiver to HK (cost $32 to ship it)...got a replacement DPR-2005 a few days ago. Hooked it up...same thing. Exactly the same thing.
Checked all the wires - using good quality 12ga stranded O2-free copper for the speakers, very short (less than 18" since the receiver is on a shelf below the SurroundBar)...optical from the Comcast DVR and DVD recorder. Everything is cleanly connected - no shorts. Tried another DVD player connected with optical - same results.
Went to test tone (DTS mode) on the DPR-2005 - cycled through L, R, C, RS...as soon as the LS kicked in, the hiss started and stayed on through subsequent cycles until I exited and started it again. (Same thing happened with the DPR-1005 that I RMA'd.) This eliminated the other boxes - now, the problem is isolated to the receiver and the SurroundBar.
Disconnected the LS and RS wires from the SurroundBar and connected them to my old JBL's...total silence...cranked up SPR and lotsa stuff blowing up on screen (and through all speakers)...but no hiss. Reconnected the RS and still no hiss...reconnected the LS and HISSSSSSSSSSSSS. Tried the opposite - same result: As long as only ONE of the SurroundBar surround channels is hooked up (either one, doesn't matter) and the other connection is hooked up to an external speaker, no hiss. Both hooked up: HISSSSSSSSSSS.
Packed the SurroundBar up (figured there had to be a short in it somewhere) and exchanged it - hooked up the new one and SAME RESULT: HISSSSSSS.
So...now I've switched out an $800 receiver with a $900 receiver and swapped out the SurroundBar with another one...almost $2k for just these components and I've got frigging HISSSSSSSSSSSSSSS.
Anybody got ANY idea WTF the problem is?
Remember...two DIFFERENT model receivers (both HK), two SurroundBars, no shorted connections to the speakers or receiver (high quality copper), optical to the external components (though I can reproduce the hiss in test mode on the receiver when it isn't connected to anything). Only happens in a surround mode - DTS, anything 5.1.
I'm going to call Polk and HK in the morning to see if there is some incompatibility between the SurroundBar and HK digital path receivers.
I'm really po'd by this entire problem - I could have bought a cheap Theater-in-a-box for a fraction of the cost of this setup and not have had any problems. I don't WANT a crappy T-i-a-b...I want THIS to work.
Sorry for venting but has become a very expensive problem.
Thanks for your help.
