Digital X Bus

Draw a digital word clock fl ow chart for your
system. This will help you verify a logical
connection scheme. One piece of equipment
connected incorrectly can mess up your entire
system. Rats!

The following illustration shows a common sync

setup, using the Digital X Bus as the master word
clock source and a hub to distribute to other digi-
tally connected devices.

Master Word Clock

Out From Digital X Bus

Here are two more sample setups that include

the Digital X Bus and other digital devices which
depend on accurate and solid word sync.

Use expensive, properly impedance-matched

cabling! It’s worth it!

Verifying Word Clock Sync Between Devices
and the Digital X Bus

When the Digital X Bus is set to “Internal” in
the Clock Card Setup window, it generates word
clock as a master device. All other devices must
be connected as slaves.

Tip: A quick way to open the Clock Card Setup
window is to touch the sample rate display in the
upper-right part of the screen, next to the L/R
meters.

If the Digital X Bus is slaved properly to a mas-
ter word clock source, the sample rate indicator
in the top menu bar (right screen) lights con-
tinuously.

If the Digital X Bus is improperly connected as
a slave to the digital network, or not receiving a
valid Word Clock at the WORD CLOCK IN con-
nector, the sample rate indicator blinks.
