This reminded me of something that really truly happens with my system. I don’t think it matters but I have a Denon AVR 4806 ~10 yrs old & we have outside speakers. Although no one is allowed to touch it, once a yr sound starts coming out of the outside volume switch. It’s very faint & you can feel the switch plate vibrating a little. A call to my stereo store & after some... push that, turn that switch all the way to the right & then flip that toggle down twice & once up... its gone. So, can some kind circuit or set of wires, in the volume switch, vibrate when you “cross the streams” & cause that sound? It’s usually the radio or what I’m trying to play outside from my iTv iTunes.
A Ghost in the System? Music Thru Speakers with Preamp Disconnected
I disconnected my preamp yesterday completely from my system in order to install some constrained layer damping tape. The DAC was on and receiving music, but the signal chain between the power amp and the dac was completely broken due to the preamp being removed. BUT: I could hear very low volume, but very clear, music playing thru the speakers! And no, I was not intoxicated. How is this possible? Cool stuff. Thanks.
