Question

I made a quadrophonic set-up --> routing in audio/midi configuration (mac OS 10.13)

test tones for each output/speaker

 (each output  is linked to a seperate speaker)

output channel 1 , test tone (specifically for speaker 1) works, but bleeds in monitor 3

output channel 2 , test tone (specifically for speaker 2) works , no bleeding (the only correct one)

output channel 3 , test tone (specifically for speaker 3) works but bleeds in monitor 1 & 2 (stereo)

output channel 4 , test tone (specifically for speaker 4) bleeds in output 1, 2 and 3

---the 4th speaker isn't receiving audio at all and the rest bleeds in I don't know what all.

So, this is a problem .. Any suggestions ? (is it me , you, the hardware or my computer ? )

Answer 1

Sorry made an error on speaker 4.

I did a few other tests :

 output 1 = linked with 3

output 2 = linked with 4

output 3 = linked with 1+2 stereo

output 4 = linked with 1+2 stereo

°°°but how can I use the output channels one by one for a separate monitor?

I'm using a stereo jack to XLR for monitor 3 and 4. Could this be the problem?
