8 Chapter 5-Wordclocks 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. Normally, 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 connector, 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. 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 beforehand. 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.
