20 Most Recent Peavey PR15 400w PA Speakers Questions & Answers


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.

Yes it unscrews. Use a oil filter wrench it will make things easier

Passive speakers with 1/4 inch jacks do not define either as input as they are wired in parallel...

Assuming the speakers you added were each no less than 8 ohms this should NOT have overloaded your amp.If you have no sound you have probably blown your amp some way.

Note some amps can be blown if they are on and EITHER side of the speaker cable touches a ground. If the amp is running and a 1/4 inch plug is pulled, it shorts and can blow the amp.

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

Try connecting them to another amplifier...you can use the speaker output of a guitar amp as a quick test. If the amp (and mixer) check OK, it sounds like you are about to become good friends with your local speaker reconing shop.

Remember...Distorted Audio Can Kill Speakers even at low volumes. It happens because sine waves become square waves. Google it for additional information.

those are Red Dot Lamps. people most comonly know them as red dot fuses, ( whatever ) it just goes on the crossover to protect your hfd. if it blew you might want to take time to check your Tweeter.

black and red will goto 1 speaker. and blue/yellow to the other. typically red and yellow are + and black and blue are -. the crossover board might tell you which is which where they solder to it. but i'm pretty sure the black/red goto woofer. try hooking up both to woofer and listen to it. 1 way is going to sound horribly wrong lol. that will mean you hooked up the tweeter leads to the woofer. but DO NOT HOOK UP WOOFER LEADS TO TWEETER. thats why i say to do it on woofer.

If you failed to turn off the amp before changing speaker cables you have fried something. Since the plug shorts when unplugging, if the amplifier were on, the amp would sense the short and will often fry the amplifier or the speaker. You don't mention what the amplifier was. If the speaker were daisy chained to other equipment a ground loop probably formed and blew out the woofer. The horn often has Peavey's "SoundGard" circuit so it probably survived. NEVER change speaker cables while amp is on. ALWAYS secure the 1/4 inch type cables through the handle of cabinets so they can'tbe inadvertenly pulled out and burn up equipment. Your amplifier driving one of these should be rated at no more than 200 watts RMS. These "400 watt Prrogram" ratings are for the birds... fake advertising. Put 400 watts into this RMS and it blows out.

There is a speaker protection network in most of Peavey speakers protecting the tweeter horn.

It consists of a Polyfuse (round disk about the size of a nickle or quarter, a resistor and an incandescent bulb.

Circuit can be found at: (go to last post attachment) http://forums.peavey.com/viewtopic.php?f=26&t=2260

Copied from earlier post I made for another.

For the MOST PART the lamp is NOT the primary path for the speaker current, the POLYFUSE is and is a low resistance until it is overdriven.

The bulb is a 12 volt bulb and is nominally 2.1 amps when used on 12.8 volts.

If this is in regards to the other problem mentioning 32 watts and 12.8 volts... this bulb is NOT 32 Watts, it is 32 CP or 32 Candlepower which is NOT Watts in general. The lamp is actually around 27 Watts when run at its ratings.

It is important to realize that the lamp and the resistor are there ONLY as a "soft" path when the POLYFUSE opens due to overcurrent. When the polyfuse cools, the lamp and resistors are effectively shorted by the Polyfuse and most of the current again flows through the polyfuse..

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).

Put the red on the + side and the blkue on the - side. SECURE the wires so that their weight does not pull them loose again. You can pop amps when speakers come loose...
