Wordclock Connections & Termination
For correct operation it is essential that the wordclock cabling be terminated correctly. The
03D has a wordclock termination ON/OFF (75
Ω
) switch on the rear panel. Wordclock is a
TTL signal, and IN and OUT connections use BNC connectors. Three wordclock
distribution examples are shown below. Note the 75
Ω
wordclock terminator switch
settings.
1. Parallel Distribution Box
In this example, a parallel distribution box is used to distribute the wordclock signal among
devices. All wordclock terminator switches are set to ON.
2. Using BNC T-bar Connectors
This example is similar to the above except that T-bar connectors are used. In this system,
only the last device’s wordclock terminator switch is set to ON.
3. Daisy Chain Distribution
In this example, the wordclock master is a digital multitrack recorder. Both 03D wordclock
terminator switches are set to ON. This method of wordclock distribution is not
recommended for large systems.
