This format cannot be automatically detected at the receiver side.
Quad Speed (176.4 kHz, 196 kHz)
Quad speed MADI does not have a standardized frame format. Therefore S/MUX 4 is used. The encoding
works the same way as S/MUX 2, except that four consecutive channels are used to transport one audio
channel. This reduces the available number of channels to 14 ("56 Ch." setting) or 16 ("64 Ch." setting).
When using MADI, the sample rate of the incoming MADI signal and the expected frame
format of the outgoing MADI signal must be set in the device.
9.2.2. Connecting Two Identical MADI Signals for Redundancy
The coaxial MADI input can be configured to automatically switch to an existing MADI optical signal in
case the coaxial signal fails. While existing routing and clock settings from the coaxial MADI input are
kept, the port’s name is changed to
MADI Auto Input
and its icon changes to reflect the feature. The
failover is seamless if the active input loses lock abruptly (e.g. one of the cables is unplugged).
The user is notified of the lost signal with a warning and redundancy can be
re-established.
For a seamless failover, the two MADI signals must be identical. However, only the SYNC
and LOCK states are evaluated to confirm the current input state. It is therefore possible to
send two different signals to the M-1610 Pro as long as they are in sync.
To create MADI redundancy:
1. Switch on "enable MADI redundancy" in the
coaxial
tab of the
INPUT
section. The port will be
renamed to MADI Auto Input.
2. Create a routing from MADI Auto Input to any output.
3. If the device should also slave to MADI Auto Input, choose it as clock master in the
CLOCK
section.
4. Connect both MADI signals with identical audio.
To create MADI redundancy using the web remote:
1. Open the MADI Coaxial input port in the routing view.
2. Click the
icon that appears within the port.
3. Toggle the switch "Auto Input" to
ON
.
