Legacy Denon and popping subwoofer


Novice Member
Hello…I have a Denon AVR-5700. According to reviews it still is one of the best sounding AVR”s ever produced and compares to some of the separates sold today. Even though a 5.1, for my needs it is more than enough. Anyway, I have a Klipsch sub connected via the subwoofer outputs. While in operation the sub sounds great and I observe no issues. However, when I switch channels on the television or change the inputs, the sub produces a popping sound.

I recently switched out subwoofers to determine if the subs were the problem, but to my dismay, both units produced the same popping sound. This tells me that it is a problem with the Denon. I don’t want to replace the unit so I was curious if anyone else has experienced the same issue and, if so, is there a work around.

Thanks for your help.
