The SREV1 checks the selected source to see if a usable wordclock signal is available. If
such a signal exists, the SREV1 locks to it and the corresponding FS LOCK indicator,
44.1 kHz or 48 kHz, lights up.
If a usable wordclock signal is not found, the SREV1 will not operate and the FS LOCK
indicators flash, as shown in the following table. In this situation, you must select
another wordclock source or correct the external wordclock source. This condition also
occurs if a previously selected external wordclock source is disconnected, the device
supplying it is turned off, or the external wordclock is neither 48 kHz nor 44.1 kHz.
The following table shows the indicator status when the SREV1 is synced and locked to
its internal wordclock or an external source.
Internal wordclock
Lock = yes
Sync = yes
External wordclock
Lock = yes
Sync = yes
The following table outlines each step in the transition from wordclock unlock to lock.

If the external wordclock frequency is neither 44.1 kHz nor 48 kHz (for example, it's
32 kHz), the transition from unlock to lock will stop at step 2 and the SREV1 outputs
will remain muted.
