Good afternoon...
Have a question around my last-gen PVXp-12 (powered) enclosures. I've been noticing that these units are exhibiting momentary "drop outs" under higher-volume use, even with NO CLIP lights - they quite literally just mute for less than a second, then keep going. I'm have a small rental set of these boxes crossed with a DBX-DriveRack that is only giving them ~160Hz and up (the rest handled by subs) - so they're not seeing a ton of low-end stress at all.
Additionally, 2 of the 4 of these units will (at times) refuse to power up - the power LED blinks for just a moment, and then goes out. Initial inspection of the power module didn't reveal anything obvious (loose connector, burnt boards, etc). However - I did notice that when they do fire up, one corner of the power module (next to the switching FETs) shows VERY high temperatures around a set of resistors...IR thermometer is showing ~240F +.
Are there any known issues with the last generation of power modules in these units (power supply, etc)? I see the updated version have slightly different power specs, which makes me thing the power unit was changed.
If there is a difference, what options do I have for fixing / upgrading these units?

Re: PVXp-12 Issues
There's one of these speakers on clearance locally (unless somebody snagged it) for just over $200 CAD. I was thinking of picking it up....
But now that I see these issues, I'm thinking better of it.
HEY PEAVEY: What's the issue???

Re: PVXp-12 Issues
I've only had one customer that had this issue. It would only happen when he would clip the system. We sent in the amplifier section and, while I'm not sure what Peavey did, he hasn't had the problem since.
