Swapping Aux to Groups.

[Bielefeld]

Hey guys I have a question for ya. I am running sound on a Allen & Heath ML3000 and want to swap the Aux. 1-4 to the Group 1-4. There is a group/aux reverse button above the Aux.'s but it isn't sending to the groups. I know that I can still run my Aux.'s with the knobs already there but I would prefer the sliders of the groups. If anyone can help out that would be great thanks!

(P.S. I am not talking about the VCA's. On the ML3000 there are 4 groups right underneath the first 4 aux.'s. Just wanted to clarify.)

I believe that the GRP/AUX Reverse switch switches controls but not basic routing. In the normal mode the Group signal goes through a Talkback summing amp, through an insert, through a fader, through a mute button and then to the meters and then on to the Group output and master outputs. The Aux signal simply goes through a rotary pot and out to the Aux out. When the GRP/AUX Reverse switch is engaged the Aux signal then goes through the Talkback summing amp, insert, fader, mute button and then to the meters while the Group signal goes through the rotary pot. But the output routing after that is that same in either case, the GRP/AUX Reverse switch does not switch what signal appears on the outputs, it only swaps the related controls.

So if you want to use the faders for Auxes instead of Groups you don't need to change any wiring or connections, the Aux signals should still appear on the Aux outputs even if you have switched it to use the faders to control the Aux signals.

Thats what I thought! Now is there any reason that that might not work? I tried it today figuring that it is just a switch and that I didn't need to change anything but it did not work. Then I tried switching the wiring to no avail... Both my boss and I can not think of any more options. Any ideas?

So you have signal getting to an aux output in the normal mode but when you engage the GRP/AUX Reverse switch and raise the fader, also making sure it is not muted, that signal is no longer there?

Yes, yes and yes.

Everything works when not switching, and like I said earlier this isn't totally necessary but I would like it. I have tried searching through the ML3000 manuals but can not find a solution.

I have an ML3000 and usually run Aux 1-4 on the group faders. Pushing the little blue buttons should do the trick. Aux 1-4 still route out aux 1-4 on the outputs no matter which orientation the board is in.

If you've double checked everything is as it ought to be, a trip to the shop may be in order depending on how much you'd like the use the Aux/Grp reverse ...

Thats what I thought, but somewhere along the line something is wrong. I have it patched to Aux 1 and 2 (1 is direct line to the stage, but because of cable issues I have patched channel 16 to Aux 2 and pulled from the snake onstage), I have signal to all the monitors on stage, then I switch the aux to group (via pushing in the little blue button) and the nothing. Groups are not being used, there is no line to either group 1 or 2 on the back of the board, they are not muted nothing else changes except for the complete loss of signal to the monitors.

I know this is probably obvious, but check the group insert jacks to make sure nothing is plugged into them, and try exercising/cleaning them if they've been sitting idle for a long time.

And, in an effort to isolate the problem, try running something through the groups in both regular and reversed modes to see if they work.

Also, check the aux/group outputs right at the board. Don't rely on the wiring going to the stage (even if you swear by it that it's good).

Just make sure that it is in fact the board, not something else.
