PA Power amp Connection Question
« on: October 22, 2019, 01:38:27 PM »

This should be an easy answer, but I cannot find it online.

I have a Behringer Xenyx 1222 mixer and just purchased a Behringer NX4 6000 to replace the existing power amp. The mixer has a L & R main output. The NX4 has A,B,C,D input and 4 channels out (ABCD). How do I connect the L & R out to the power amp input and have A, B, C, and D outputs with independent volumes on each?

Y adapter seems the obvious solution, but some people seem to think Y cables should not be used??

Any thoughts would be greatly appreciated.

I see no  reason Y adapters will not be suitable for your application if the on board switches don't give you input configuration options.

The general rule of thumb that I learned is that it is okay to split a signal with a wye cable, but don't combine signals with a wye.

Put both 'mode' switches in mono, and both 'crossover' switches at full range.
Put Left and Right from the mixer in A and C respectively.
A and B will be Left, C and D will be Right.

I thought it should be something like this, just didn't have the correct combination. Thank You.

OK, so I connected this way. Now on the power amp A = left and C = right but B and D volume controls do nothing. I'm trying to get a L & R Mains and L & R Monitors all with independent volume controls.

There's not many switches or controls, is there anything else I might be missing?

If that's the case you will need to undo the switch settings that linked AB and CD and run individual inputs to each channel. Linking channels like you did before will only let one gain knob per linked pair control the sensitivity.

1) Do it right
2) Do it over until you do it right

Agreed, it looks like splitters (Y cables ) then.

Thank You.

You should not be controlling volume at the amp.  Doesn't your mixer have aux feeds for the monitors?  If not consider an XR-12 as an upgrade to that mixer.

I agree.  Monitors require a mix that's different from house, which is usually accomplished by aux mixes.  (Some boards call them by different names.) Each aux mix has its own dedicated output from the board, which feeds into its own designated input and corresponding output on an amp (assuming a passive speaker system).

Hey Carl... Welcome to the forum but you will need to change your display name to your real name as per the forum rules you agreed to when you joined. Just a  heads up ......
