UR28M volume knob spdif

Quick question:
Do all the output controls like volume knob, dim, mute and mono also work on the spdif out? I might want to use a dedicated DA converter behind the UR28M, connected through the SPDIF, but still use the controls on the UR28M since it’s very handy ot have it on the desktop and not have to reach down to the rack.
Thanks for any clarification!

No…level is not controllable.

Ok, thanks for the info!
