The MX400 and Digital I/O
stream, and it is necessary to change the clock source from the MX400’s internal clock
to Digital.
Furthermore, the MX400 only receives external clock sync on the S/PDIF A input.
This means when using both Digital inputs (A and B), the devices that are connected
must be synced to a common clock source to work properly with the MX400.

If only S/PDIF B input is to be used, the MX400 still needs the external clock source

If the Clock Source isn’t changed to Digital when digital input sources are selected,
there will be synchronization problems between the incoming digital audio stream
and the MX400’s processing, and the System Input Source menu will display DIG NO
LOCK. When the MX400 is properly synchronized with the incoming digital audio,
the System’s Input Source menu will display DIGITAL.
The MX400 only runs at 44.1 kHz or 48 kHz sample rate (using internal or external
clock sources). Do not connect external digital outputs to the MX400 that run at higher
sample rates (88.2 - 192 kHz) as the MX400 cannot accept them.
