S3 (or GPIO Port)
3-position toggle switch for interface selection (
MAIN - RED
undant
- AUX
).
MAIN
:
MADI input is forced to MAIN port (split mode master AUX = 0)
RED
*:
MADI input is used from either MAIN or AUX port
AUX
:
MADI input is forced to AUX Port (split mode master MAIN = 1).
*
S3 has to be set to
RED
for interface selection via the GPIO port, as well
as for 96 kHz/64-channel operation.
S4
Rotary switch for baud rate selection of the MADI 2 link
