Hey all, new to the forum. been reading about this stuff allot but im still a noob, i have some basic electrical classes under my belt but I'm pretty oblivious to audio stuff.
anyway, my problem is this, I have a set of cheap fisher 15" cabinet speakers (I know there kind of junky, but for $50...) and a nice vintage pineer sx680 that i realy like as a receiver, but the amp is completely blown on the right bank and it sounds like crap. what im looking to do is get PA amp to run the fishers and use the pioneer as just a head unit for the radio. I'm looking at this peavy mark III mixer/amp Peavey MP 4 Mark III 100H mixer amd and i know it will work but I am just unsure of the sound quality of an amp like this. I'm not looking for super high quality sound, but i don't want it to sound like junk either. would a set up like this get me by for just decent sounding bass and not too much distortion at high volume? I will mainly be using it party s.
on a side note, would i be better off with something like this as far as sound quality PEAVEY MONITOR POWER AMP even though it seems like the wattage is a bit low?
again, I'm not looking for super high quality so take it easy one me, I'm just a college kid trying to get some decent sound in the house for partys!

If you are 'using it for parties', make sure you don't buy an amplifier that can blow out your speakers.
You could get the Pioneer repaired or just keep your eyes open for another old SS Receiver on the local used market. (Thrift store?)
A mixer/amp isn't what you want, I think. You are going to use the 'Preamp out' or 'Tape' connection on the Pioneer to feed a power amp?
Using a PA amp: If you could find a Behringer 500 power amp, that would be a good-quality power amp which is adequate for good hifi. Probably too powerful for your use, though.

i got the peavy for $70 because the shops all want $90 minimum without parts to repair the pioneer. its 50watts per channel which is fine... I am on an extremely tight budget, I have hit about $150 so far and i don't want to go any higher.
anyways, I cant figure out if i have it hooked up wrong or if the amp doesn't work. as soon as i hook the speaker outputs up the thing speakers hum real bad, regardless of how much volume i have on the pioneer or the peavey. the guy i boght it from tells me its probably because i need a shielded wire and not just speaker wire soldered to 1/4" jacks...
any help is appreciated.

Have you downloaded the manual for the Peavey?
To test the Peavey, get yourself some RCA to 1/4" phone adapters/cables and hook up your CD player/source to one of the mixer inputs.
You DO NOT need shielded speaker cables.
Leave the Pioneer out of your system for now.

I had a quick look for the Peavey..this is a 4 channel MONO powered mixer? (ie up to 4 inputs mixed down to one output)
Please explain how you plan to use this in your stereo setup.
I must be missing something here....

I just want the amp to power my two 15" speaker cabinits. it has two 1/4" phone jack outputs on the back. it says 50watts per channel "minimum amplifier load 8 ohm - speaker jacks paralleled"
Does that Pioneer model have a pre-amp out on it? Mine does but it is in the other room and I can't remember what the model is right now. If it does it is a lot better pre-amp than that mixer is. Run from the pre-amp out to an amp and then to the speakers.
If it doesn't run from the speaker outputs on the pioneer to the speakers. Either way you will have stereo. Forget about that mixer and mono garbage.

No kidding. Are you sure it isn't 33 volts AC? It is probably best not to have any DC on the speaker outputs. If the amp is old enough you might burn it up running it without the speakers connected.
so the amp is probably bad then? I'll call the dude tomorrow and see if i can get my money back.
As a hard up college student, you would be better advised spending what little money you have on food and heat, not audio gear.
If you bought the mono reverb amp, try and get your money back (especially as it hums !)
The monitor amp looks better spec and is 2 channel (stereo)
Don't be fooled by the output numbers. 35w rms is LOUD. and could even blow your cheap speakers.

Pre-1985 Peavey stuff has some crossover distortion at low levels because they didn't intend the stuff to be used at low levels. The blanket condemnation of Peavey stuff is a bit of blind prejudice, in my opinion,but your device is 1979 the PA only days. . The 1979 CS800 uses the dual diode bias circuit from the 1960's GE transistor manual and probably academic precedents, which is primitive. The cool thing about Peavey is the availability of schematics & industry part numbers. The annoying thing about Behringer is the lack of public schematics and the non-disclosure agreements to the servicemen that do have them. If you use your brain to re-bias the Peavey and replace dried up capacitors for $20 in parts, you can have something useful at low levels, if you wish. Or, you can learn to repair your Pioneer. Peavey's have a reliable power supply and an adequate heatsink, which are the expensive parts of any amplifier project. If you put in two chip amps instead of the current Peavey electronics, you would have a stereo rig and know a lot more when you are done than when you started.
The mono only is a problem, but not if you get decent sound. I've just come off an 8 year stint of too much overtime, everything I owned was broken, and nothing could be bought that wasn't imported from C****. I listened to music only on a clock radio with a 1" speaker and a TV with 2x3" speakers. Having bass & treble with low distortion is more important to me than having stereo. Boom boxes produce stereo, but sound like ****. Going from 2% to .1% distortion is a big improvement and not expensive. Having speakers that will reflect an amp that produces .001% distortion, is not a hobby I can afford on a pension.
I like having a mixer as the hub of my music system, I'm using an upgraded disco mixer. It is nice to be able to play CD's, LP's, or radio, without running around to switch the source and adjust the volume. I'm collecting parts to install another mixer on my HDTV-HD tuner-MD-tuner-DVD player-VHS player rig which requires fiddling with the volume every time I change source.

I called the guy and he says hel get me my money back so the peavy is gone. my next option is iether the 35watt peavy i posted origionally or I'm looking at a early 90s pioneer vsx5700s, its made in japan and rated at 440 watts but the only thing that scares me is it says surround sound on it and its all digital... I'm afraid its a little too new to be of quality, what do you guys think? I can get it for $35 and the pawn shop will let me hook it up and run it BEFORE i buy it.
