Operation
AES/EBU signal statuses
When AES/EBU is enabled, the status of the signals is displayed:
LOCK
and the
sampling frequency
indicates a digital audio source is connected to the AES/EBU input, the signal delivered by the
source has a format supported by the controller’s digital audio board, and no loss or fault is
being detected during data transfer.
For example, LOCK 44k1 indicates the digital audio source provides signals of sampling
frequency of 44.1 kHz.
LOCK-WARN indicates the incoming digital signal has a sampling frequency that is out of the nominal range,
but it does not lead to sound cut.
UNLOCK indicates the incoming digital signal is faulty and leads to sound cut.
If the fallback mode is active, UNLOCK on channel pair AB automatically switches to channel
pair CD. FALLBACK(CD) and the status of the signal on channel pair AB is displayed. Refer to
section FALLBACK MODE (p.46).
The LOCK status is re-acquired after at least 500 ms of stability.
INVALID
indicates non-audio data in the payload or errors in the AES/EBU transmission.

Reverting from fallback
When the LOCK status is recovered on channel pair AB, reverting to the initial input mode is manual.

AES/EBU LOCK 44k1
Procedure
1.
From the
INPUT MODE AB
menu, press the OK key.
2. Turn the encoder wheel to select the input mode.
3.
Press the OK key or the encoder wheel to validate.
