PA help - active crossover settings

Evening all,

Just have a quick question - how are you all setting up your crossovers on your PA (for the band) when powering tops and subs with different amps - ie 1 amp for x2 tops and 1 amp for x2 subs - again theres differing opinion out there. [/size][/font][/color][color=#000000][font=Arial][size=3]
Set up is MIXER-CROSSOVER-AMP/AMP-SPEAKERS[/size][/font][/color][color=#000000][font=Arial][size=3]

Moreover, im confused how to actually wire the crossover up to my 2 amps (1 for tops, 1 for subs).[/size][/font][/color][color=#000000][font=Arial][size=3]

The back of my crossover has:

Channel 1 and 2 inputs (simple enough they come from the mixer) - theres 2 inputs on each amp L and R so thats 4 connections from the crossover, but the crossover has 9 potential outputs? [/size][/font][/color][color=#000000][font=Arial][size=3]

CH2 INPUTS
1.High Bal - High Bal
2.High UnBal - High UnBal
3.Low Bal - Mid Bal
4.Low Unbal - Mid - Unbal

1.LOW SUM OUT

CH1 OUTPUT
1.High Bal
2.High Unbal
3.Low Bal - Low Bal
4.Low Unbal - Low UnBal

Which of these outputs would go to the inputs on my amps?[/size][/font][/color][color=#000000][font=Arial][size=3]
And as a rough guide, what would you set your frequency crossovers at (this is for a 4 piece band PA with drums, bass, guitar, vocals).[/size][/font][/color][color=#000000][font=Arial][size=3]

Any help extremely appreciated - thanks in advance[/size][/font][/color]

Think ive solved this now:

Im running it:


CHANNEL 1 OUTPUT
High Bal this goes to amp for tops LEFT
Low Bal - Low Bal this goes to amp for subs LEFT

CHANNEL 2 OUTPUT
High Bal-High Bal this goes to amp for top RIGHT
Low BAl - Mid Bal this goes to amp for subs RIGHT

and the LOW SUM OUT is for a 3 way MONO system?

It was the 2 different names on the Low Bal - Mid Bal that threw me!

Yep.
Most active xovers can be used for a stereo 4 way (two tops,two subs) or mono three way (sub,mid,top)
You sussed it right.
