EXT WORD CLOCK INPUT
If an external word clock source is attached to this BNC connector, the TrakMaster Pro
will attempt to synchronise to it. When the unit is correctly locked to the external clock
source, the ADC LOCK LED in the DIGITAL section on the front panel will
illuminate. The LED should remain permanently lit; any flashing or flickering indicates
jitter or other timing discrepancies, which need investigating. The frequency being
received at EXT WORD CLOCK INPUT should be selected on the ADC card to
achieve lock.
