Not really - this setup makes for relatively short audio connections (from my back-stage Cantabile rack to the mixer / stage box), and the connection to my keyboard setup is a single CAT 6 network cable that runs all USB connections plus the HDMI signal to my touchscreen. I have a “KVM Extender” that does that bridging - works super-solid in my rehearsal room setup; I expect it to do the same on-stage.
This is the “magic box” - here’s the relevant thread around this topic:
"Festival" Cantabile setup - experience-share
The network cable is sufficiently shielded that interference is not an issue. And of course I carry a backup - in my case a long USB cable and hub and another long HDMI cable, in case this construct should somehow break down. I might have to move the Cantabile rack a bit closer to my setup if this happens, but at least I’ll be functional.
Cheers,
Torsten
