Connecting the MADI Output

The MADI optical Duplex SC housing is located beneath the PFL
bus link connectors on the rear panel of the M16. This comprises of
two optical connection points, one transmit (Tx) and the other re-
ceive (Rx). See
NOTE: The receive (Rx) feature on the M16 is NOT implemented.
Carefully remove the cover from the duplex SC housing. This will re-
veal the two optical connection points. Take care to store the cover
in a safe place.
Take the optical cable and carefully insert the mating connector into
the transmit (Tx) connector on the M16, making sure that the locat-
ing key on the cable connector housing is aligned with the locating
slot on the transmit (Tx) connector. Once correctly inserted, the op-
tical connector housing should lock into place.
NOTE: Confirm that the optical connector is securely locked in
place and that it is correctly located in the transmit (Tx) connec-
tor.
NOTE: The M16 Mute switches only operate on the analogue
output section. It is not possible to mute channels on the MADI
output.
Connect the other end of the optical cable to the receiving device.

MADI Setup

The M16 supports both 56 channel MADI and 64 channel Extended
MADI protocols, as well as 48kHz and 96kHz sampling frequencies.
Selection of which protocol and sampling frequency to use is deter-
mined by the capabilities of the receiving device (check with the
manufacturer of that device to determine the MADI specifications).
Selection of the MADI parameters is made via two momentary
switches on the rear panel located adjacent to the MADI Duplex SC
housing. Any settings are stored and automatically recalled upon
powering on the unit.
3.6.3

Sample Frequency Selection

Selection of either 48kHz or 96 kHz sampling frequency is available
on the M16.
Toggle the 48k - 96k momentary button to select the desired sam-
pling frequency. LED indication provides confirmation of selection.
3.6.4

MADI Channel Selection

In 48kHz sampling mode, the M16 can support both 56 channel
MADI and 64 channel extended MADI protocols.
Toggle the 64/32 56/28 momentary button to select the desired
MADI format. This will be either 64 or 56 channels respectively. LED
indication provides confirmation of selection.
