Test the regulator chips FIRST before ANY replacement. These chips are very reliable and the problem is LIKELY elsewhere.

The 7815 and 7915 ar 15 volt three terminal regulators in TO220 style packages. Three leads. The 7815 is plus 15 and the 7915 is minus 15.

CAREFUL as the input and ground pins are in different order between the two.

FIND the specs and picture with Googling the numbers.

These chips will be soldered in AND MAY be screwed or clamped to a heatsink OR just standing up from the board.

The "Built-in overload-protection circuitry" is just doing its job...protecting the speaker from damage. Lets look at your system 1st. Is your power amp or powered mixer underpowered which requires you to turn the volume controls up past 1:00? Big systems play loud at moderate setting where-as small systems must be max'd out to reach those same levels. Pol-mount your speakers for better coverage as your ears are not attached to your shoes.

Hi,

Best and safest is to have a good electronicus check it out.
i've worked on these kind off things, and i assure you not everything can be simply solved without experience, especially when talking about a decent type like Behringer ;)...

Hope this is helpful, and greetings,

Olivier.

Bad news...you've blown the tweeters. Overdriving the mixer/amp creates distortion on the amplifier which heats up the speaker voice coils and eventually causes damage. Because of their small diameter voice coil windings the tweeters fail first (opens up like a fuse element does) followed by the woofer making a scraping sound (deformed voice coil) or not working as well. Warranty service because you blew out the tweeters? Don't get your hopes up.

1. PLEASE use enough power for the venue that you have. A high powered system will run all night at 10:00 (physical volume knob setting) than an underpowered system set for 2:00.

2. Get speakers off the ground and closer to your audience's ears. Audio from speakers on the floor must battle surfaces that actually absorb some of the sound....carpet, drapes, etc. And besides, legs can't hear that well.

Check the internal wiring. There may be a loose connnection and this is VERY hazardous to you amp !!!

These may also have a self reseting fuse and that MAY be damaged.

You should discover the problem when you open up the unit.

You would need a 2 or 3 way crossover, depending on whether or not you biamp your tops. Simply go out of your main outs on the mixer into the input of the crossover. Go from the low output of your crossover to your low power amp input (subs), and the high output of the crossover to the high power amp input (tops). Then go from your outputs of your amps into the speakers themselves.

I doubt that there is a problem with the unit. Usually people have problems with their cables or the speakon plugs themselves.
Unscrew the connector that is used on both ends and double-check their connections. Sometimes the screws that hold the heavy gauge wire in place, come loose. Also make sure that they are in the right places. Sometimes you have 4 connections. Make sure they are in +1 and -1 connections. Every once in a while you'll find a quirk unit that requires you to use +2 and -2 instead. Look at the back of the amp. It should tell you which numbers it uses. Make sure you check the same thing on the speaker end also. If you have a meter or continuity checker, use it to make sure it's wired right.
This is a professional piece of equipment. They don't go bad easily. Make sure you tighten those connections real good and that you pay close attention to the engraved numbers on the speakon connectors. (That is if they are quality connectors. The cheap ones may NOT tell you the numbering or the phase, ((+ or -)). Hint: The negative one is always closest to the outside of the plug. You'll have to study it to understand that. The screw terminals on the inside have 'walls' on both sides of it. Those are the + connections.
Also, check the switches on the front. You may have one of the switches in the wrong position or setting. Also if you're using phantom powered mics, you have to turn the phantom power on or else they will not work. Hope this helps.

Do you have the mics and dongle system accessories? Your question does not state if you have them or not. If you do have these accessories, and you only want to use the wired option, remove the dongle so it stops searching for the microphones.

Hope this helps.

Hello Doug, obviously for what you are saying, you would have a problem in the effects processor of your Behringer, I suggest you use an external processor to corroborate that the problem is not in the shipping bar, or in the allocation of returns
If you have technical knowledge, disarm the mixer and control the internal connections of the effects processor, see if there are no loose solders
I sent you the link to download the circuits of your PMP5000
If you do not find the origin of the fault, look for a specialized technical service
I hope you can solve the problem
Greetings Franco Dosil

Hola Doug, evidentemente por lo que comentas, tendr?as un problema en el procesador de efectos de tu Behringer, te sugiero que utilices un procesador externo para corroborar que el problema no esta en la barra de env?os, ni en la asignaci?n de retornos
Si tienes conocimientos t?cnicos, desarma el mixer y controla las conexiones internad del procesador de efectos, observa si no tiene soldaduras flojas
Te env?o el link para descargar los circuitos de tu PMP5000
Sino encuentras el origen de la falla, busca un servicio t?cnico especializado
Espero puedas resolver el problema
Saludos Franco Dosil
