About Wordclocks
For correct operation and digital-to-analog processing, it is essential that the DA824 is
wordclock locked to the digital audio device transmitting the digital audio signals. Nor-
mally, the DA824 locks to a wordclock signal derived from the SLOT digital audio
inputs, but when a usable wordclock signal is present at the WORD CLOCK IN con-
nector, this is used instead.
The LOCK indicator lights up when the DA824 is locked to the wordclock source and
synchronized to the digital audio signal. It flashes if the DA824 is not synchronized to
the digital audio signal.
Wordclock Hookup Examples
In this example, the DA824
sources the wordclock signal
from the SLOT digital audio
inputs.
In this example, the DA824
sources the wordclock signal
automatically from the WORD
CLOCK IN connector.
Note: When the wordclock source is changed, the DA824’s analog outputs may produce
noise, especially if an MY8-AT I/O card is installed, so turn down your power amps before-
hand. Likewise, when changing the wordclock source on the wordclock master device (e.g.,
AD824 or DME32), turn down your power amps beforehand, or turn off the DA824.
