As Steffen said “it is that simple”, but even more capable.
Inside dLive you have an (approx) 800 in x 800 out non-blocking switching matrix (S Class) that you can go from any Analog/DX/Slot to any Analog/DX/Slot/ME on MR or Surface. There may be an upper limit on concurrent connections (not published), but there isn’t a known restriction on what-can-be-connected-to-what.
If you look at all the slot options and DX options, the routing (and SRC) capabilities rock.
Analog. AES. Dante. Waves. MADI. Map between any of them as you wish.
