5 Wordclocks

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.
