From the advice of a thread I created a while ago I'm going to put a crossover into my motley pa system. The goal being to send only the lows to my Peavey nitro bass half stack to use it as a sub woofer.
This is a terrible noob question but how do I connect the crossover into the system? I'm going to get a Behringer CX2310 crossover and based on the images of the back it has 2 inputs but one of them says not used. What I want to do is run from a small mixer to the crossover and then 2 outs to a crown running 2 yamaha speakers (Mids/Highs or full range) as well as one out to a nitro bass half stack (lows only). I'm just not sure how to properly hook it up and I want to make sure I order the proper cables.
Thanks guys,
Brad

The "Not Used" input label is only valid when the crossover is being used as a mono 3-way crossover.
Apart from that, I'd recommend you study the Behringer manual - its quite comprehensive on hook-up options.
Exactly which bass amp is it?
Its going to need two inputs if you want to put bass guitar through as well.

I found the manual, I'll look through it tonight thanks.
It's a Peavey NitroBass head on a 4x12" Peavey cab. I'm only going to be using it like a sub for a halloween party we're having (assuming thats ok?). My band days are over.

The 4x12 PV cab may not put out enough real "bass" below 50 or 60 Hz. Electric bass cabs don't really go spectacularly low - the exceptions being high end stuff with a 15 or 18 on the bottom. And if you try to boost down low those 12's might not like it. May be fine in the application, but I wouldn't expect too much out of it - or push it crazy hard.
If the amp tolerates an instrument input then it will certainly tolerate a mixed music input.
For the op, run the low out from the crossover to the bass amp and the high out to your crown amp.
Thanks for all of the info guys. I'll post a second question here to avoid starting another thread if I can.
I was looking at my setup and the more I read about pa systems I'm realizing how little I know! My Yamaha speakers are 8ohms impedence but my crown ce2000 amp is rated at 4 ohms on the back. From what I've read on the data sheet I think that the amp should work for any impedence speaker and the 4 ohms was just chosen as point of reference? correct?
My Yamaha S115V speakers are rated for 500 watts program and the crown amp puts out 400 watts per chanell on 8 ohm stereo. They've always seemed to work fine so I'm assuming that 400 watts is not too underpowered for them?

PA amps will drive any speaker of impedance greater than or equal to the amp's lowest rated impedance - sometimes they'll say 300w@8ohm, 600w@4ohm, so 4ohm is the lowest impedance it can drive.
Assuming a perfect power supply (which they never are), you get double power when you halve the impedance. With infinite current drive and enough voltage swing, you could do 300w@8ohm, 600w@4ohm, 1200w@2ohm, 2400w@1ohm, etc etc.
In terms of decibels, going from 400w to 500w is negligible. The Yamahas will be fine.
There's a good article by Rod Elliott about amplifier power: the site appears to be down at the moment, but try Googling and see if you can find anything.
