Are you wanting the direct outs to mute when a DCA is muted? The GLD doesn’t have dedicated mute groups. The DCAs are your only option.
If this doesn’t allow you to do what you need, it’s probably not possible on the GLD platform without some sort of workaround.
DIR OUT SRC pull-up window
The global source for the input channel Direct Outputs can
be set here using the drop-down menu. This setting affects
all channel Direct Outputs:
Post-Preamp
Post- HPF
Post-Gate
Post Insert Return
Post-PEQ
Post-Comp
Post-Delay
Touch the buttons to set:
Follow Fader (pre/post fader)
Follow Mute (pre/post mute)
