Pr15 has no high frequency - Peavey PR15 400w PA Speakers

but you would have to go to Peavey direct for service info.

"Overdrive Channel: high frequency noise as the gain and volume are increased."

This is the expected result, you are experiencing feedback. Try turning the "Contour" knob all the way to the left and turn down the tone knob on your guitar.

You will require 4 heavy gauge 1/4" speaker cables in order to connect all 4 cabinets to the Behringer power amp. Usually two longer ones from the power amp to the sub woofer cabs. Then two short ones from the second "thru" jack to the upper 15" cabs. Remember the entire audio frequency range is going to all four speakers. Sometimes you will have problems balancing the low frequency levels between all four cabs depending on the loading of each. A more desirable way to do this is with a bi-amped arrangement. This way two seprate amps are used for the subs and 15" cabs and you control them independantly.

Of course I can't be sure but most amps don't have fuses on the circuit boards anymore. They use protect circuits, they may have blown your amp and yes it could be expensive. Are there indicators on the front panel? LEDs on that shouldn't be?

Removing a magnet from a tweeter is oftten fatal to the voice coil or element in piezo drivers. If you can see the screws, often a right-angle driver may be able to remove them.

Actually its pretty funny thing with those speakers is the "fuse" is Actually called a Lamp in this case. These are what they call a " Red Dot Fuse ". in all the years i've been doing this i've never thought to look up the value haha. Just have to know there are Red Dot lamps and Blue dots and No Dot. If you examine the LAMP you should see somewhere close to the ends ON THE GLASS a color dot of some kind. almost like someone painted it on there. Red Dot Lamp. any parts distributer for people like Harbinger, Peavey, and B52 will KNOW what your talking about

The consense is that the yellow is positive... However, if these come from a 1/4 inch jack, the color that connects to the TIP of the jack is the positive one..

i) I believe you can access the fuse by removing the Input Jack Panel.

ii) If fuse is OK, then unscrew the horn unit, take off one speaker wire & measure resistance. If it is open circuit then you can order a replacement horn diaphragm (if you feel confident to fit it to the horn).

Here is a site that has PR15 fuses... shown as a 2.1 amp. Very strange value, and it must strictly be for the tweeter portion as 2.1 amps is nothing for a speaker... I don't know that I believe this site.

If you have a Guitar Center near you, inquire there.
