hello, can anyone give me some advice on properly connecting a crossover. I use a carvin 1644 powerd mixer. Do i jsut hook the left and right main outs to the crossovers inputs, then out to my external power amps? (i use the internal amps for monitor mix for bigger shows.)
Then here is the kicker, how would i hook a crossover into my mixer using the internal power amps? I would use this for a smaller show and rehersal since most of the band goes direct for rehersal, i think it would clean up our sound a little using the crossover.
thanks to whoever can post. I love you all(spoken like ozzy)

Yup, that's how you do it. L/R from mixer into crossover. L/R high out to one amp, L/R low out to the other. Then out from the amps to the hi/low inputs of your speakers.
They do have separate inputs for high and low, right?

Kinda need that, unless you are putting that xover in between tops and subs.
For the second question, run it the same way, and patch the xover outs into the power amp inputs on the back, using
unbalanced cables. Using unbalanced cables overrides the internal routing, and feeds the xover signals to the amps. Patch L/R low into amp 1&2, and L/R high into amp 3&4.
Or, you could go from the mono out, and just use one side of the xover, and two amp channels. Patch from the xover into amp inputs 1 & 2 with unbalanced cables. Set the routing switch to L/R M1 M2, and your two monitor feeds will still power monitors from amps 3&4.
The only pain with this mono configuration will be hooking up the speakers, as you need to plug two cables into each output for your mains. If the amp had banana outputs, you could just stack them. Since that thing has both speakons and 1/4", you can get a couple speakon to 1/4" adapters and use the 1/4" and speakon jacks at the same time. So say you have the lows from the xover going to amp 1. Run one cable from the amp 1 speakon out to the low input on one speaker, and one cable from the amp 1 1/4" out to the low input on the other.
Do the same for the highs and you are all set. Just don't mix them up.

Your tweeters will blow almost instantly if you put low end through them.
