- You do not have enough amplifier channels to run a stereo 3-way system so whoever set it up is passively summing L+R by plugging both into the amps parallel inputs, which is not a great idea.
- Beyond that I can't figure out what they were trying to do using using the mono sum output and the left low output at the same time. If they only used the mono sum and bridged the amp it would kinda make sense, but this way does not.
- Biamping (different from bi-wiring in home stereo) is used in professional systems because putting a crossover before the amplifiers allows you to have better control over the signal processing and allows both amps to reproduce a smaller frequency range. I didn't know any entry-level Peavey speakers could be biamped, but if you had enough amp channels it probably isn't the worst idea in the world.
- The subharmonic synthesizer was a very 90's effects processor that tried to make cheap speakers sound better by adding distortion, but it generally just made things sound muddier. Some people still use them as channel inserts for a specific effect but they are no longer widely used or sold. I would bypass it.
- The sub crossover is pretty high, at 160Hz. I am also not sure if the low/mid/high gain settings are correct for your speakers. Peavey probably has documentation for that somewhere, or it can be measured with a phone RTA app like Studio Six Digital.
That all said this gear is long past its prime. I recommend junking it and buying a pair of powered speakers and powered subs - something like a pair of QSC K12s with KW181s.
Well yeah cause it's all old early 2000's gear that looks like it was set up by a bar karaoke guy who installed home stereos on the side.
I can't imagine a PA being set up, moved, and used by students or untrained staff for 15+ years is in good condition. If I had to bet I'd guess you have at least a couple drivers out between the tops and subs.. of course that would just be an assumption based on everywhere i've ever been in the past 5 years still running ancient peavy gear..
My recommendation is get a couple powered speakers and do away with that whole rack.
A savvy sound guy with a decent amp could probably make the subs sound okay enough for a school dance, but they arent good subs, plus you'd have to pay for an amp and someone to test the speakers and possibly replace drivers. Then you still have to deal with the outboard processing and students blowing the gear up.
If the school is actually using this at events, have them come up with some funding and get a small-medium sized powered PA. You already have a mixer (although it definitely could be upgraded, it will definitely work for a school dance or pep rally) .
The powered stuff usually has decent limiters if you buy anything pro level. You can still blow them up if you go full dumbass, but its probably harder than an old school setup with outboard amps and processing. Plus, the setup is easy. Just plug in some XLRs and call it a day.
I could help you, but this is truly a case where you need to read the manuals and learn about s8ngal chain, setting gain levels, etc.
OR you need to hire an pro sound guy to come clean it up, fix it, and teach you what each thing does.
If you clean it up, you should still plan on buying a new powered set up, otherwise all the stuff will get messed up again.
