Hi, not sure how to set this up, but I have main outs and a sub output which drives a sub woofer. The two faders are linked so that turning down the main output also turns down the sub output, and this is fine.

Not sure how to set up the routing so that if I change the level on an input channel that is driving both the main and the sub output so that if i change the input level on main it also changes the corresponding level on the sub mix. What is happening is that I turn down the fader on input (on the main output) to 0 and then the audio is still being output to the sub.

Hope that's clear and anyone have any suggestions on how to do this?

thx
