Schematics for DSWmicro PRO 3000 plate amp

mpitogo

Hi all,

I’m looking for schematics for DSWmicro PRO 3000 plate amp.

I have two units. One uses audio signal auto sense on the LFE port and it’s working fine for automatically turning the sub on and off. The other is close enough to my receiver it uses the 12v trigger. Recently, I noticed the 12v trigger unit no longer works to turn the sub off. I tried with either audio signal auto sense or the 12v trigger. When I manually power cycle the sub the auto sense and the 12v trigger works to turn the unit on and for some time it works then hangs in the on position. Once it hangs in the on state, removing the 12v trigger or the audio signal has no effect nor does the 3 position switch for auto sense, off or 12v trigger, only using the mains power switch turns the unit off.

I’d love a copy of the 2000 for myself as well lol

I have a workaround which is to use a switched port on a surge protector. The switched port is triggered on/off with my amplifier. This works great except for the large thud everytime we turn the system off and it’s at least a few times a day as it’s in our main family room system.

Hello,
I recommend sending an email to: Ken.Carter@soundunited.com for amplifier schematic requests.

I contacted support and have a ticket open explaining the issue. Will try this route first.

Well I think she finally kicked the bucket. Won’t power on at all. Checking the fuse but I doubt it.

In case there is any interest, I found this service center.

What was the price of the repair if you don't mind me asking?

Repair for DSW microPR0 3000 which includes 90 days warranty $175
1 year extended warranty $45
Return shipping $15

In all not bad considering subwoofer replacements can be pricey for the specs. While the sub is a diminutive little box, it really packs a punch, 1000W RMS 2000 peak. And I run dual identical subs each independently measured by Audyssey multieq.

Finding a replacement to fit the space is extremely difficult. The end result is small sub with similar dimensions and sub par performance, many out there or pricier subs with similar dimensions and performance eg JL Audio E-sub e110 $1699ea or better performing Velodyne DIgital Drive Plus 10 $3299ea.

Hoping I can get at least another year with the pair, been maybe ~10 already. Yes I know SVS and HSU and REL exists but their subs and get rather large and heavy.

Thanks for the info. These don't come up for sal too often but good to know just in case.

Polk support must be very busy, just got a response 9 days after opening a ticket. I was asking for how much a replacement amp would cost and they sent me what looks to be a standard response. For one my sub is well past warranty and second even if I wanted to there is no way I will be able to find the receipt or CC statement.

Wow you found a place that could service this amp? I bought my 3000 with a dead amp for $100 and when I called Polk to get a repair quote, they called a couple placed while I was on hold with them, and nobody would touch my amp. So I bought a brand new amp with a 3-year warranty direct from Polk for $300, shipped from their Vista, CA facility.

I have a 2000 and Vista just sent me a 3000 board for 200 bucks so I’m going to try it

My other (I have two) 3000 kicked the bucket. Does anyone know the failure mode of these plate amps? Any suitable replacements?
