Word Clock In/Out
House Sync
Generator
A master word clock generator is preferable for larger digital setups.
Word Clock In: Receives word clock (sample clock) from another digital device such as
a digital video deck, digital recorder or digital mixer.
Word Clock Out: Sends word clock (sample clock) to another digital recorder. Word
clock is always output, whether it is generated by the internal clock or passed through
from the word clock input.
75 On/Off: Termination for the word clock input can be switched on or off in the
Sync Card menu of the PatchMix DSP application. Normally word clock termination
should be left on. If you have problems with a weak word clock signal, try turning
termination off. See Word Clock
The diagram below shows the proper way to connect and terminate a serial word clock
chain. Using a BNC "T" connector ensures that word clock is precisely in phase for
both devices. The middle device has termination turned Off and the last device in the
word clock chain has termination turned On.
