AV2 problem. Help!
Posted by: Somesuch on 06 January 2004
Running an AV2 in my home theater.
Since installing it (about 3 weeks ago?), I've noticed that it seems sensitive to static. Walking around the room, I get the occasional discharge against the sofa or what-not, and there's a pop/click from the speakers if the AV2 is on. The pop/click is especially loud if I touch the case and get a discharge.
Last night I received an especially painful shock (when changing the volume manually) and then the center and sub channels went mute. I verified this using the test tone facility.
Power cycling the AV2 brought it back to its senses. But now there are some weird intermittent behaviors:
1. Sometimes, mute doesn't work --> only some speaker channels are muted; the rest are simply attenuated. Power cycling seems to help.
2. When mute doesn't work, volume behaves strangely: when turning the volume down, it's as if the speaker channels don't change volume at the same rate. i.e., the left, center, and surround channels will attenuate correctly, but the right speaker and sub stay loud until a moment later.
The mute problem is something I saw before, actually: I home demo'd an AV2 about a year ago and experienced the same issue - I chalked it up to an early production problem and promptly dismissed it.
Don't believe there's a ground problem with my system. I had been running a Myryad MDP-500 pre/pro for a couple of years with no such issues.
Thoughts?
Thanks,
E.
