Question about Behringer Pro Mixer Djx750 Professional 5 Channel Dj Mixer With Advanced Digital Effects And Bpm Counter
Wire mixer to eq to amp
Line level output of the mixer would go into the line level inputs of the EQ, and the EQ line level outpputs to the line level inputs of the amplifier. If you are faced with a mix of unbalanced inputs or outputs, to balanced inputs or outputs it gets a little complicated because you need to matrix the balanced signal to unbalanced load and vice versa. There is no single answer to doing this either.
RCA jacks are unbalanced, 2 conductor 1/4 inch connections are unbalanced most of the time. XLR and 3 conductor 1/4 inch jacks and plugs can be either balanced or unbalanced.If either are wired so left and right are a single ring or tip on the 3 conductor 1/4 inch jack, it is unbalanced and they would share a common ground lead. XLR wired with one pin common with shield and right and left have a single conductor on the plug or jack, that is unbalanced.

Behringer only gives schematics to their authorized service people.
I find I can usually trace stuff out as needed as the mixers are a very symetrical repeating circuitry.
Most components are readily available from other sources.

The first thing to do is to swap teh L & R INPUTS to the amplifier. Did the speaker that works change?
If som the problem is with the setting of the mixer deck. If it did not change, then the problem is with your speaker wiring of the dead speaker, the speaker itself, or that side of the amp.
If the working speaker did swap, that means problem is with the mixer. The question then becomes how are you connecting to the mixer. You should be using TRS 1/4 inch connectors or preferably XLR from the MAIN outputs. These are balanced outputs connections.
If the inputs are from one of the mono inputs, the PAN control for that channel will control how much goes to each speaker... If at center, both will get same signal.
There are so many possibilities that I can't evaluate them until you try the test to find if it is problem of the amp or the mixer that I have given you to try.

It appears that both these use a 50K pot in the identical circuit and it is UNLIKELY they re-engineered very much so it is likely they use the same pot.
Behringer parts service should be able to tell you.

DO NOT REPLACE A FUSE if it blows. You will do additional damage to the unit internally.
When these blow, there is damage inside that must be repaired before restoring power.
To get an exact replacement fuse holder it is best to get it from Behringer parts. This one has a switch in it depending on which way the fuse carrier is inserted.
