Digital X Bus

•Draw a digital word clock flow 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 digitally connected devices.

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.

Here are two more sample setups that include the Digital X Bus and other digital devices which depend on accurate and solid word sync.

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.

Use expensive, properly impedance-matched cabling! It’s worth it!
