How do i connect a crossover to my mixer

alan62

Please help ,my band recently bought new passive bass bins but now we are told we need to get a crossover to control get the best out of them and not to blow the tops,can anybody explain what way these crossovers work and is there a certain way of setting them up.

A cross over is similar to a filter.

You take a left and right output from your mixer and insert into the crossover.

Treble (small) speakers

You set where the cross over frequency is, Any frequency below that goes to the bass bins and above goes to tweeters. It mostly protects your treble speakers from being destroyed by trying to reproduce the massive bass waves in comparison to the tiny treble waves

How are you powering the new subwoofers? A more detailed description of your setup would be required to really figure out what should be going on.

An active crossover goes before the poweramp and is usually in a self-contained unit.

A passive crossover goes after the poweramp and is usually built into the speaker cab.

If you're using an active crossover, you need an amp for every component of the signal - the subwoofers have their own amp, and the tweeters have their own amp.

If the "top" contains a normal speaker as well as a tweeter and you've already been powering it from a single amp, then you can safely assume (since the tweeter hasn't already exploded) that the speaker cab is internally wired with a passive crossover and you're no more likely to blow it.

Cheers guys, as you can prob tell i have'nt got a clue about crossovers ,but if it helps our setup is .

Dynacord powermate 1000 out to 450 rms bass bins then up to 400 watt HK tops,but we were told to put a crossover in the mix so that we don't blow the tops.
Hope this helps!

From what you posted it sounds like you're running both bins and tops from the 'main out' of the Dynacord. I had quick look at some pics of the mixer on the web and it appears to have two speakon outs.

Are you looping the amplified signal from the subs to the tops? If so, a passive crossover between the sub and the tops should do.

Yeah looping the bass bins to the heads,so basically just put a passive crossover between the bins and the heads,is there a certain way i should set the crossover or something i should watch out for.

Thanks again for your help!!

If the tops have taken a full range signal in the past then you're not at risk of blowing them now for want of an extra crossover.
