My setup is as follows:
- Denon AVR-3806 (which I'm thinking of upgrading, but I want to make sure this issue won't happen if I were to upgrade)
-Tru-audio in wall speakers and in wall passive subwoofer
The subwoofer is connected to an Audio source AMP100 amp.
So when I'm playing a DVD via the Denon DVD player, I noticed the sub has a noticeable "pop" as if it turns back on from sleep mode. It's fairly obvious, even the wifey notices.
Initially I thought this was because I was playing movies via the Samsung TV Allshare, connected to the receiver via the TV audio output. And figured that signal is 2 channel. BUt it even dows this witht he DVD player.
Background info, the audio equipment came with the house, so I didn't set this up. It's all in the basement, so at times, it's harder to troubleshoot. Everything appears to be correct as far as wiring, wires from receiver to amp, to subwoofer. Not sure what else to check.
