VCA Group Fader & Master Fader does not work

[Dave Dicson]

Check the soldered in jumper wire links under the VCA (13) card on every channel modules. They need to be in 1 position when there are recall cards and the other position when the recall cards are removed. They my have been changed?

That only bypasses the 03 MPX card if not in use. Computer still needs to be bypassed for VCA to work.

I have seen instances where E13 VCA cards have had wire jumpers installed to bypass the computer.
It could be there, on the channel mother board, back plane....lots of places.

Is this even a problem that you are trying to correct, or just for your own curiosity?

All of the faders are working, so its not a problem.
I just want to know where it is.
I checked the fader bus card, there are no jumpers, looks clean.

I am also wondering, i couldnt measure any voltage on the pins where the jumper should be.
0volts.

Thanks,

I found the Jumper.
There is a little Wire jumper on the 611 Board, directly under the VCA Card.
It connects the Computer Send and Return directly on the 611 Board.

Thanks,

As-I-said, the jumpers under the "13" card must be installed, if there is no computer being used.

Yes Dave, you said it and I overlooked it somehow...
Depending how you set the Jumpers you could also bypass the MPX card.

Thanks!
