In the section about renaming inputs it states this for the “NAME X = STRING” command via the RS-232 port:
AES1 - 0
AES2 - 1
AES1+2 - 2
SPDIF1 - 3
SPDIF2 - 4
SPDIF3 (It calls this “TOS” but the default name is actually “SPDIF3”) - 5
Network - 6
USB1 - 7
Does “8” work to rename “USB2?”
Normally I’d just try it, but I thought I’d ask.
