One mixer and two power amps.

hello DJs

I'm no DJ but I just bought a Numark CD Mix-2 and two power amps to use at home... just for parties at the house.

Now my question is, can I connect two power amps to a single mixer (a CDMix2 in my case)??

I want one amp to power two subwoofers and the other one to power a pair of JBL JRX115 cabs.

Can I just buy a "Y" and split the signals out of the mixer to both amps?

In your case, you'd want to get a crossover.

a crossover? hmmmm... whats a crossover for?

cant I just split to signal from the mixer to both amps? or would i damage the amps or mixer if I do this?

If I really need a crossover whats the best cheapest one? Im on a tight budget right now after spending $$$ on what I already got.

A crossover is a device that splits an audio signal into two different outputs, dividing them at a frequency of your choosing so all the higher frequencies go out one output and the low frequencies are separate.

If you just split the signal coming out of the mixer you will be sending a full range signal to speakers that are only designed to handle a smaller part of the audio signal, which is never good for the way they end up sounding. The crossover will keep the highs out of the signal that goes to the subs, and the bass out of the signal that you run your mid/high's off of, and that's pretty much always a good thing.

Which one to get depends on how much you can spend on it. Behringer makes them as cheap as $80 or so but they're not known for making good stuff. Companies like Dbx or BBE also make cheapish ones that would probably be a little better.

I bought a Behringer FBQ3120 Crossover/Equalizer!

I read on some reviews that they're really good, especially for the price.

BTW, How can I connect my Numark MixCD-1 to the Crossover.

The mixers output are RCAs and the Crossovers inputs are XLR or 1/4" phono.

Can I just buy an RCA-to-1/4"phono adapter?

another question.... what's the purpose of the XLR jacks??? Why not use the regular 1/4" phono jacks or RCA?

XLR provides better shielding from ambient radio frequencies and such that can pollute a signal that is being passed through a cable. Would you notice the difference in your application? Probably not...

For unbalanced lines less than 10 ft, you should be OK. Anything more than that, I would strongly recommend balanced lines. Did I ever tell the story about my former boss who bought 200 feet of 2 core unshielded cable to run sound upstairs via RCA aux outs from the mixer?
