MX500
Furthermore, the MX500 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 MX500.

If only S/PDIF B input is to be used, the MX500 still needs the external clock source
to be connected to S/PDIF A.

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 MX500's processing, and the System Input Source menu will display DIG NO
LOCK. When the MX500 is properly synchronized with the incoming digital audio,
the System's Input Source menu will display DIGITAL.
The MX500 only runs at 44.1 kHz or 48 kHz sample rate when using S/PDIF and inter-
nal or external clock sources. Do not connect external S/PDIF digital outputs to the
MX500 that run at higher sample rates (88.2 - 192 kHz) as the MX500 cannot accept
them via S/PDIF.
