Description
The top menu line displays the currently selected
sustained silence delay before the ‘Silence’ LEDs are
illuminated, and (optionally) the relevant GPI outputs
are asserted low.
Active audio channels are indicated by the numbers
1234 (ST1Left = 1, ST1Right = 2, ST2Left = 1,
ST2Right = 2). Any silent channels are indicated by
the symbol ‘s’.
The bottom line shows the reference source in use
(REF followed by VIDEO, AES or W.CLOCK). Aref
instead of REF indicates that the source in use is an
alternative
because the selected source is not suitable
or not available.
RATE shows the sample rate and AES output rate.
Note:
Each input channel is equipped with ‘near silence’ detectors. If the audio signal levels
are sustained at below –50dBFS for more than a selected period of time, an indicator for
each channel comes on and an appropriate GPI output can be asserted low.
Stereo 1 silent in audio channel 1 or 2 will illuminate ‘silent’ LED 1 and assert GPO5
low if enabled.
Stereo 2 silent in audio channel 3 or 4 will illuminate ‘silent’ LED 2 and assert GPO6
low if enabled.
