Does MONO in the Control Room work only for the MAIN outputs and not headphones?
Depends, what you mean with "headphones". Anyhow - The Dim-, Recall-, Speaker B-, Mono-, Buttons only affect the assigned Outputs for "Main Out" and "Main Out B" (Dim/Recall only if they are linked) . And this for a good reason...
As you already found out, assigning Speaker B to your switches between the Main Out and Main Out B including the state of the Mono Button.
I do a lot of mono checking under headphones and would like a proper control for this in a future update if possible
There are already lot of possibilities for achieving your goal, depends on your workflow.
An example:
Lets say:
- the PH9/10 out is connected to your Headphones for Mono checking
- you want to have them in your Control Room Section
- you want to switch between Mono/Stereo with just one button and without affecting any other channels/faders/etc...
- your incoming stereo signal is visible on Playbacks AN1/2
- you do not want to "waste" any Fader Groups just for this
So:
1) In Control Room click Assign, select "Phones 1", map to PH9/10
2) In Control Room click Assign, select "CUE/PFL to", map to "Phones 1"
3) In Playback row, split Playbacks AN1/2 from Stereo channel into two separated Channels, make sure both Pans are spread (L100 for AN1 and R100 for AN2). Both Faders are set to 0.0 dB Position
4) Select your "Phones 1"/"PH9/10" Submix (it should be highlighted by grey background now)
5) In Playback Row, now make sure both Pans are 0 Position. To avoid overload (because we sum up the signal), set both Faders to -3.0 dB Position.
-> so, now the default for your "Phones 1" or "PH9/10" is a summed mono signal from PB AN1/2, while the others stay on stereo.
-> if you want to switch your "Phones 1" or "PH9/10" to Stereo, just click the green CUE Button in your "Main Out" (or any other Output Sub) and its signal gets routed to your "Phones 1" (because we selected this in 2) )
