Sorry if OOT.
Is there any possible to link 3 surface t112 and which is each has iDR (3 sets).
Which is the best connection could be happen.
And what is limitation control or feature each side of surface if those connected.
DANTE in all iDR, all DANTE connections using a GBIT switch,
DANTE Controller as patchbay/crosspoint matrix
no control linking, only audio data interchange possible
hope this helps
