Bel Digital Audio Limited
Front Panel Description
SDI Lock LEDs –
four tri-colour LEDs, for SDI
inputs 1 to 4. Each illuminates continuously when a
valid SDI video signal is detected at its input, and the
colour indicates the interface standard in use, as
below:

* SAM64 monitors all incoming embedded audio streams and if
found to be non-compliant in format will flash the appropriate LED.
Note that Bel Digital Audio cannot guarantee correct operation
when non-compliant SDI streams are present.
Sync source selection –
a 3-position toggle
switch for selecting the audio sync source.
The switch’s ‘down’ position is latching, while its ‘up’
position is momentary. Repeated ‘upward’ presses
on the switch scroll through the possible external
sync sources. The adjacent amber LEDs indicate
the currently-selected source. When the LED for the
desired source is on, the switch may be placed in
the latching ‘down’ position to prevent inadvertent
further changes of sync source.
