Here is a link to forum that someone has posted the soundguard protection circuit down the page:

The 1156 lamp MAY have slightly different shapes but is an automotive lamp. If the bulb is blown, the polyswitch fuse is likely blown as well.

I have 2 peavey sp2 bx well I was pushing them really hard and blew the black widows. Now I have got a replacement and hooked it up and still no sound out of them. I do have the horns working but they...


The lamp bulb fusing is just on the horns. Check the Black Widows individually with an ohm meter for continuity. If the speakers themselves test OK, you most likely blew the crossovers. Peavey service (877-732-8391) can rebuild most of therir crossovers in house and they generally are cheaper to fix than replace.

Is there a fuse in a peavey sp2 for horns


there are 2 of them in the new ones....but ya probably the blew diaphrams...unless they are old one...then it could still be in the crossover..need to know the exact SP2 model you have, as they have changed the speaker again and again over the years.

Peavey sp2xt speakers horn makes no sound when plugged into normal input. Horn works fine when plugged into the high side of the crossover.


High side speaker input jack defective, as they are switch also and if you plug the wire from the amp in full range and no hf sound but connecting directly to the bi-amp hi does, then your female 1/4 plug at crossover is defective for sure.

Hi,i got the circuit diagram of the soundguard protection u have sent, but the resistor(50w 5ohms) used in your circuit. in my circuit two resistors(25w 10ohms each) are used in parallel. so in my case...


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..

I have 2 peavey sp 5 and a pwavey 2600 amp . i wanna know can i hook a peavey 118 passive sub to one of the sp5 and how would it sound?


You would send high as well as low to the sub and unless the sub had a built in crossover it COULD get muddy sounding. The specs SEEM to indicate the 118 DOES have a low frequency crossover so it SHOULD be OK... How would it sound? An 18 inch sub normally adds to the sound of a system... You MAY need to PAN over to send more power to the one side with the extra load on one side. Often people use two sub's... one for each side so it is balanced.

Whats the wattage of the bulb used in peavey sp2 crossover, my sp2 peavey speaker bulb is blown


The lamp is an "1156" lamp... replace with that part number. Here :

http://search.digikey.com/scripts/DkSearch/dksus.dll?Cat=524517&k=lamp%201156

Or you can find it at auto parts store.

LIKELY the polyfuse device is ALSO gone... Probably similar to this one (1.1 amp, trip 2.2 amp):

http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=F2010-ND

or this one (1.85 amp, trip 3.7 amp):

Need a capasitor for crossover


Find them at Digikey.com. Search first for "Capacitor" then select "Non-Polar"

HOWEVER there is a part that LOOKS like a ceramic capacitor but it is NOT. It is a "polyswitch" which is a resettable fuse. Go to the Digikey.com site and search for "Polyswitch". Then select 60 volt in the filter and Radial... see if you can find the item. Also consider opening a second speaker if you have it to get the number off one that is still OK. This is part of a protection circuit and needs to be replaced with exact device.

Hello, What is the proper way to connect an Ashly XR1000 Crossover and a Pyle Pro PTA1400 power amp to my Peavey XR8600 so I can use 2 subs? The subs are not powered, but do have a passive crossover...


Here is a link to the manual:http://www.peavey.com/assets/literature/manuals/00513220_7.pdf I didn't look at the manual for the crossover but this is probably the way I would do it. Look at page 13 in the manual : Come out of the Main out (31 in the diagram) into the main in of your crossover. Go out of your crossover Hi and Mid out setting back into Power amp In 1 (labelled 32 in the diagram). Hook your speakers that you normally use to the output jacks on the back of the Peavey. Make sure you match the output impedances. Go out of your crossover low output into the Pyle power amp and out of the Pyle into your subs. Make sure the impedance ratings of all your speakers match the output impedances of your amps. You will only be running in Mono mode as that is the signal output of the Peavey mixer. You can run faux stereo by using the Main monitor Out as 1/2 the pair and the Main Out as the other 1/2 to both channels of the crossover but you won't be getting a true stereo pan mode.

Peavey SP 2G has a burnt ceramic capacitor in crossover


Ive been through this. Although it certainly appears to be a ceramic capacitor, its actually called a polyswitch. .65 amp. Parts express carries them. Part no. 071-256.
