Wireless F/X surround whistle noise on shutdown

Hi all,

I just purchased a wireless F/X surround speaker. A problem - when I power down my home theater system, the F/X makes a very irritating whistling noise - like a bomb dropping in an vintage WWII film. My wife and cat both don't like this, and I may have to return the F/X if it can't be resolved.

I should note that I am using an Outlaw Model 7125 amplifier. Would it help if I use the line out from the AV receiver/preamp (an Outlaw 990)? But would that affect the sound quality?

Thanks much.

    Harv, the sound you describe is likely caused by your Outlaw amplifier's capacitors discharging when you power it off. It's actually a fairly common question here, not specific to the F/X surround. If you connect the F/X surround directly to your 990 (great pre/pro; I also have one) you should avoid that problem, and I believe the sound quality will be just as good or better.
