Denon AVC 11SR Playing up!

Posted by: Blueknowz on 14 March 2010

Whilst using 5.1 & 7.1 I am experiencing pops,clicks etc, with both Sky HD & DVD Acram but not when using Stereo etc at first I thought it was the HD box! could it be a cable problem?
The HD box is connected via Optical & the DVD Coaxial. Or is the Amp on the way out?

Had the same problem with the AV2. It turned out to be the mother board. Expensive to fix. Hope it is not the ame for you.

I contacted Denon U.K. Received this email:

Thank you for your email.



Does this issue occur on non-digital sources? If you try connecting an analogue stereo cable from any of the sources you experienced this on and setting the amp to 5.1/7/1 stereo does this happen again?

It maybe worthwhile also changing the INPUT MODE on the amp to either AUTO or PCM to see if this resolves your issue.

Finally does the amp receive test tones on all speakers without defect?

Hi James







Thank you for your email.







Further to your response can you check to see if this issue occurs when set to PCM if you are outputting digital to the amp. If this is the case you may want to try an alternative connection from your Sky HD box if possible. Eg toslink connection instead of coaxial. Please note that you would then need to assign this through the DIGITAL IN ASSIGNMENT menu.





If you only hear this through one speaker you may want to try swapping the speakers/cables as a test.





Finally you may want to reset the unit in the following way :- ( Please note that this will default all of the values on the amp and it will need reconfigured/recalibrated again )











We hope that this information provides a solution.
