1
OFF: AUX is used as CH33-64 at 88.2 / 96 kHz (factory default)
ON: AUX is used as redundant port at 88.2 / 96 kHz
2
OFF: 64 MADI channels (factory default)
ON: 56 MADI channels (standard setting for legacy products)

OFF: Slave – clock from MADI signal (factory default)
[Block diagram: MASTER/nSLAVE = 0]
ON: Master – clock from local generator [Block diagram: MASTER/nSLAVE = 1]
6
OFF: Master mode sampling rate 48 kHz (factory default)
[Block diagram: 96k/n48k = 0]
ON: Master mode sampling rate 96 kHz [Block diagram: 96k/n48k = 1]
7, 8 reserved (factory default: OFF)
S3 (or GPIO Port) 3-position toggle switch for interface selection (MAIN - REDundant - 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
