Word Clock Select

The 02R processes audio data at 44.1 kHz or 48 kHz using its internal clock,
and can run at any frequency from 32 kHz –6% to 48 kHz +6% when an
external wordclock is applied.
Wordclock
When you connect a number of digital audio devices together, all the
devices should synchronize to one device—the wordclock master. The
wordclock master generates a sync pulse which allows the other devices
connected to it to determine where the start of each digital word is.
Although most digital interconnect protocols are self-clocking, it is more
reliable to use a dedicated line for your wordclock signal. This is especially
important in a multitrack environment where up to eight channels of
digital data may be multiplexed on one cable.
When you are using a digital device—such as a DAT mastering recorder or
a modular digital multitrack recorder—connected to the 02R, all the digital
devices in the system, including the 02R, should synchronize the
wordclock being supplied by one master device. If any device does not
synchronize to the system wordclock, dropout and/or other noise may
occur.
In Section 14, "Installing Options" on page 217 of the User's Guide, there are
examples of connecting external digital devices to the 02R and setting the
appropriate wordclock selection. Refer to this section for details for each of
the optional digital I/O cards.
Note: Wordclock is not required if you use the analog I/O card (CD8-AD) to
connect to an analog multitrack recorder.
