Wordclocks
When several digital audio devices are configured in a system, it is essential that they are all
synchronized to a single wordclock source. This is not SMPTE or MIDI timecode
synchronization. Wordclock synchronization refers to the synchronization of the digital
audio processing components inside each digital audio device. Typically, one digital audio
device acts as wordclock master and all other devices work as wordclock slaves. The
wordclock frequency is the same as the chosen sampling rate.
Even though some systems appear to work okay with several digital audio devices not
sharing a common wordclock (i.e., all devices set to their own internal wordclock), digital
audio data will not be processed correctly. In some systems this problem will be very
audible. In others it may cause subtle distortion. Be aware of this.
In a system where all devices share a common wordclock, it is important that all devices be
powered on even if just one or two devices are being used. Obviously, the wordclock master
device must be powered on. Before starting a recording session it's a good idea to make sure
that all wordclock slaves are locked to the master wordclock source. Most devices have front
panel indicators that show whether they are locked to internal or external wordclock.
Setting the 02R's Wordclock
To set the 02R's wordclock source:
1. Press the DIGITAL I/O button repeatedly until the Word Clock Select display appears.
2. Use the cursor button to select a wordclock source.
3. Press the ENTER button.
If the 02R locks correctly to the chosen wordclock source, the respective indicator appears

highlighted. See "
Wordclock Source Capable Inputs" on page 10 for a full discussion of
the indicators.
As well as internal, the 02R can derive its wordclock from any one of 19 input options. It's a
good idea to familiarize yourself with the various indicators on the Word Clock Select
display shown below. The four sections of the display, 1 1 1 1 to 4 4 4 4 , are explained below.
