ZED 16FX specific question Aux3 post fader

Hi all,

This is probably a very basic question. My apologies. I have a A&H ZED 16FX. ! want to do 3 separate mixs off the board. Fine with Aux1 and Aux2 which are pre-fader. Aux3 is post-fader and fader adjustment also affects the L/R volume. Is there a way to isolate the Aux3 post-fader monitor send from the L/R volume? Or is there another method of using Aux3 for monitor send?

According to the block diagram, it is actually relatively easy to change the source point of your Aux 3 to pre-fader for all mono inputs, as A&H has provided a solderable option for this (see image).
If you have experience in soldering on circuit boards, you could carry out this “firmware update” yourself, or ask a specialist to do it.

SQuser - thank you for the quick reply. Your suggestion is a bit out of my wheelhouse. Also the board is a donated one to a society space, so would rather not muck with it. Perhaps there is another less invasive solution? Otherwise I would just provide two mixes.

There won’t be any other option than the one already provided by A&H.
But as far as the number of independent mixes you want is concerned, with Aux 1, Aux 2 and LR you already have 3.

Is there an image of the circuit board available somewhere, to compare to the block diagram, showing where this alteration would be done? Thank you.
