Does anyone have similar problem with Pass Amp?


I'm just wondering if what i'm experiencing is normal. I have a Pass X250 and Pass X1. When my preamp is muted or turned off I get a slight hum from the right speaker. The hum is only audible when the room is dead silent and my ear is right up against the speaker. Obviously it's not a major issue however i do not hear any home from the left speaker. Is this slight residual hum from right channel only normal? Any input would be appreciated. Thanks

How long does the hum last for after you turn your amp off? I suspect the right speaker is experiencing more interference probably due to the cable being crossed with another cable. When I turn off my aleph3, there is still enough power to play music for about 2-3 seconds. So, there is definitely juice left in the amp even after turning it off.
It doesn't sound normal. Try reversing pre-outs. Does the left speaker make the low hum. I think you might be blaming wrong component. See an "audio troubleshooting guide."
Viggen has the right idea. Keep in mind all transformers hum to some degree. Some manufacturers pott them to reduce hum but that only creates a new set of problems.
