ElectroVoice P2000 stays in protect if cold

Got a used P2000 that originally had the 'limit' light on on the A side, with no output. The B side worked fine. Replaced 4 capacitors on the input board. The amp worked fine for about a year. Now, if it's cool, it stays in protect until it warms up. For example, if it's about 70F or below, ambient temp, it takes about 5 minutes. Above 70F, it works perfectly. Once it comes out of protect, it works perfectly without going back to protect. This symptom occurs with/without input or load. I hate to run it in this condition, because I might be causing further damage. Any ideas? I'm a self-taught fixer-upper, but the schematic I got from EV's website is a VERY bad scan, and is unusable.

    I agree that it's normally the other way around. :) Thanks for the suggestion. I'll give it a try. I'm suspecting the same capacitors on the B side are failing.

Normally it's the other way round, something gets hot and cuts out! The procedure for doing solving this is to spray the suspect device with Servisol Freezer Spray, when it stops functioning, if it's faulty the spray will make it come back on. But in your case I suggest you do the reverse of this. When it starts working spray a suspect part one at a time with Freezer Spray. If it stops working you have found the faulty part. To speed up the process you can heat it up with an soldering iron, plus check when you think you have found the culprit.

    When replacing capacitors make certain you fit the same temperature ones. For example if it says 105C on them replace them with 105C types. Otherwise they could fail quicker!

    I agree. I prefer to go with higher temp / voltage if I can make them fit. :)

SOURCE: i have two xti 2000 amp running with electrovoice speaker 600w

This is most likely to be a heat issue where the amps overheat and shut themselves off then cool down and turn back on. Please check that the amps have proper ventilation and that any air ducts are clean.

If you go to obd-codes.com you can read about this defect. The battery light is telling you that the charge in the battery is not a full charge. Have autozone or one like it to test the battery and alternator. I believe if you correct the battery issue the other problems should go away.

Generally thats a sign of a shorted output device, either a bipolar transistor or mosfet. Also ground faults can trigger a protect light.

Volume fades when I push it even a little bit. I have an AC 90 purchased maybe a year ago. I use it with my acoustic guitar (self-installed JJB electronics piezos straight in, no preamp) and vocal mic...


This unit has a TDA8920 dual switching class "D" switching amp chip that is thermally protected. If you heat it up it will shut down to protect against overheating. Each side of this is ONLY a 50 watt amp chip HOWEVER they run it at a lower than rated voltage that limits it to about 30 watts per side. Your dial setting number have NOTHING to do with the power limits of the unit. When you use the looper, there are more frequency components added, and all these consume part of the available power. Also make sure the mics and the guitars cannot "hear" the speakers in this otherwise high frequency feedback may occur above what you can hear and use some of the capabilty... hint... reduce the treble boost... The only way to measure the power output is to put a scope or test equipment on the output and compute the power. I suspect you are driving the unit too hard. The unit should give adequate output for a 15 foot square room to a level that *********** could just barely tolerate. Yes, the power amp chip is thermally protected and if you drive it to hard it backs the power down till it cools off.

That link doesn't work or it leads to a convoluted place where have to know more to find it.

It sounds like their service is on par with the website presentation. They couldn't even define it for you?

I'll take a feeble swing at it. The manual shows it has Event Logs. I'd start there and see what else is indicated. Eventually an understandable decode might appear.

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on; or it may turn on but produce no audio to the speakers.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'nekkid'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

The limiter probably delayed the eventual damage. Nothing prevents all damage absolutely.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech for forensics and further action.

Check for loose speaker connections at the speaker as a root cause for intermittent shutdown.

I have an Electrovoice MA-1212 That when I hook it up and power on all I get is a constant low frequency Hum. Checked the wiring and speakers on another amp and eliminated them? Any suggestions?


WIth the speakers disconnected, measure the terminals using a DC voltmeter. I suspect that there is DC voltage there where there should be 0V. If that is the case, the output transistors are shorted and need to be replaced.

Wiring tweeters.


Yes you need them. I always put them inline on the positive side. They are to protect the speakers against low frequencies. Actually, I use oil bath capacitors sometimes on pro systems. I don't see how they would work between the positive & negative that is unless they have a positive & negative side with an out and an in? Hope this helps,

Most of the car stereos are 40 to 50 watts output.so they need a stronger fuse than 3A.This kind of radios use 10A fuse.
