I recently purchased an Allen&Heath Zed-14 for a price that was too good to refuse. There is one thing about it that is a total non-starter for me, the pre-fade Auxes are Post EQ and Post insert. Given the lower price point of this model there are no internal jumpers to configure the options on these auxes. So, off to the service manuals.
I have a plan that needs a bit of critiquing. I have included the schematic for the Mixwizard set up for pre-eq aux, and traced the signal path.
I have also included the Zed, highlighted the stock signal pat,h and circled the components that see audio in red for stock, blue for modifications. There's a blue "X" where I plan to place the cut and a blue line where I plan to tap. My main concern is that when the highpass is not engaged, there appears to be no 47K pull-down resistor for C18.
Thoughts?
