Of course, if you select one of the fixed rates, the actual rate will be the same as the
rate you select. This parameter is primarily useful when using an external clock
source.

Internal Clock Digital I/O Status
When the internal clock is selected, the sampling rate of the signal at the digital
input
must be equal to the internal clock’s rate to avoid generating audio distortion.
From the
CLOCK

AUDIO CONFIGURATION
menu page in the
SETUP
area, the
SOURCE
and
SAMPLE RATE
parameters should be identical:
Possible
DIG STAT
values are
Slipping – Signal is present, but its sampling rate does not correspond with the
internal clock’s rate. A digital input that is slipping will probably suffer from clicks
or distortion. The bigger the discrepancy between the internal clock’s rate and the
digital input’s rate the greater the distortion. Some slipping may be acceptable for
monitoring or other non-critical applications.
OK – Signal is present, and its sampling rate is locked to the internal clock rate.
This is the optimal scenario. If a signal’s sampling rate is very near (but not exactly)
the internal clock rate, its status will read OK with brief interjections of slipping.
This is normal and may well not produce measurable distortion.
Unlocked – No signal is present, the signal’s sampling rate is very unstable, or
something is quite dysfunctional with the signal.
