INSTALLATION
NOTE
:
The mix-minus output board must be mounted directly in front of
the output board on the console inside base.

Cut the wire ties holding the power supply cable bundle that
passes in front of any input or output board which will be fronted by
a mix-minus board. Fold the power supply cable up over the
boards (towards the rear of the console) and remove any stick
downs which hold the ties in place.
2)
Place the mix-minus board(s) exactly flush against the
console 6-input or output board and mark the mounting holes on
the console base.
3)
Remove the mix-minus boards and drill the holes with an
11/64" metal bit. Pay particular care to keep metal filings out of the
console.
4)
Mount the mix-minus board(s) on the console base. Use the
spacers provided to raise the boards off the base to avoid shorts.
