Hi Folks,
As noted in some past threads I regularly double-assign many channels, with XLR-Y cables on the DL1608 and digitally on the DL32R.
House channels are one color, and are on one View Group, Monitor channels are a different color and on a different View Group.
All the Monitor channels are un-assigned from the house mix and groups, so even if one of their faders is raised in the L/R mix, no audio goes there.
For the House channels, I do have to be careful not to raise the fader in a Monitor view.
This provides a House mixer and a Monitor mixer, with only channel input gains shared.
The old Yamaha 01V96 with layers 1~16 and 17~32 made this really easy; I did this for over a decade.
Before that it was a split snake and separate House and Monitor mixers.
This approach obviously cuts the channel count available, and requires some extra View Group switching, but works well for me.
Biggest benefit is not having any compression on the Monitor channels, while still being able to compress the House channels.
Sometimes having different Monitor and House EQ is also helpful.
For various reasons, occasionally I still use one channel for House and Monitors, and certainly appreciate the simplicity!
Thanks and good health, Weogo
