I've got two brand new XLS 202's in my home theater and they're awesome. Really took my sound up a notch. One is powering the L and R mains, and the other is powering the center with one channel. The 202 powering the L and R mains work perfectly, but I've got an issue with the other.
The one powering my center however thumps pretty significantly at power-off - unless I turn the gain completely down. I've tried the other channel (I'm only using one) and both behave identically. I did notice one other difference between the two amps: On the 'good' amp, the 'fault' LED's 'blip' at power-off. On the offending amp, the 'signal' LEDs blip at power-off - in concert with the thump. Fans, relay clicks, etc. all sound identical from what I can tell. I thought I could hear a difference in the relay click at power on/off at one point, but now I can't tell the difference.
I'd like to leave the gains up so I can power-cycle the system with automation, but I've been manually power-cycling the amps and lowering gain on the one amp because of the thump in the center. Do I have a warranty repair/replacement issue with the new amp?
