Denon AVR speaker channel reconfiguration challenge

[Anands123]

Hi, looking for some guidance here. My 3 year old Denon AVR 4700H is producing a cracking sound from the ‘height1’ channel and it affects my front height speakers. I am trying to see if it can output the same signal on height 2 channel instead as it is free and hopefully not damaged. I can’t seem to do that as the various amp assign settings force me to use height 1 by default unless I have 4 height speakers, even in that case the height 1 will be in play for one pair and still introduce noise.

I have tried to verify that height 1 channel by changing speakers and cables but the issue seems to be in the channel itself.
Any suggestions appreciated.

Hi just nudging to see if anyone has answers

Any suggestions appreciated.

Looking at the manual, there doesn't seem to be a way to assign a single pair of height speakers to Height 2 on your AVR. If getting it repaired isn't a possibility, you're left with having to disconnect your heights and run the Denon's Speaker Virtualizer DSP for height effects.

Are you sure it's the AVR and not the speaker ? Would be good to swap the left height and right height speaker cables & see if distortion is swapped.

Thanks. Unfortunately that seems to be the case.

Yes I tried that the distortion travels with the speaker post.

Related to this scenario, is there any solution other than to get it repaired? Am gathering that the repair might be expensive as the motherboard might need to be changed.

A cracking sound has less to do with the motherboard and more to do with the amplifier section. You might want to get that checked first.

You can choose to not using that height channel, or, run a pre output to an external amplifier if you must have the height channel working. Before you do that, make sure even the pre out isn't generating the same noise. Cause if it is, it will defeat the purpose of adding an external amplifier.

I still think its better to resolve the issue than adding an external amplifier as its going to add clutter.
