Levinson 432/436 turn on 'pop'


Hello,

I purchased a few Levinson 432 stereo and 436 mono amplifiers. All of them seem to have the same 'pop' when I switch the amps on/off. It's especially bad when turning the amps on, my woofers extend outward fully for a few seconds, I'm worried it could be damaging my speakers so I just keep the amps on all the time for now.

Does anyone know if this is normal for Levinson amps or what the issue could be? I wouldn't think all 6 amps would have the same problem. Maybe some issue elsewhere in my system could cause this? I'm also using a PS Audio Premiere power conditioner.

I really don't want to lug all six 100+ lbs amps to the repair shop...

Thanks,
Chris

HAve you tried powering the amps directly from the wall socket and avoiding the power conditioner? Very few conditioners can handle the demand that high power amps place, especially the peak at turn on.
Yup, tried that still to no avail. Gunna order some Cardas shorting straps and an Integra DHC-80.2 with XLR outputs...

Did you solved this issue? I have the same exact issue running unbalanced IC. No pop if I disconnected all IC from the amp.

Did Cardas shorting straps solve it?

Thanks
