3. Use a BNC cable to plug the WORD CLOCK—OUT connector on
the back of the first 02R into the WORD CLOCK—IN connector on
the second 02R.
The 02R that is the cascade master should be receiving a wordclock
signal from a wordclock master device, such as a modular digital
multitrack recorder or other appropriate device.
Wordclock Selection
1. Power on your modular digital multitrack recorder and then the
02R units in order, starting with the cascade master.
It is always important to observe the correct order for powering up
equipment in a studio. Start with the multitrack and mastering
recorders and the signal processors, then the 02R, and finally the
monitoring amplifiers and other downstream gear.
2. Use the [DIGITAL I/O] button to locate the DIGITAL I/O 1/5 page.
If the cascade I/O card was installed properly, the 02R will identify it in
the appropriate slot.
3. Use the CURSOR buttons to select the wordclock source.
Select the W.CLK IN box and press the [ENTER] button.
4. On the 02R cascade master, use the [DIGITAL I/O] button to
locate the DIGITAL I/O 1/5 page.
If the cascade I/O card was installed properly, the 02R will identify it in
the appropriate slot. A digital I/O card should be installed in SLOT1 or
SLOT2 in order to access the direct out lines.
5. Use the CURSOR buttons to select the wordclock source.
Note: If the W.CLK IN box is not showing a proper wordclock input (no
discrepancy between the input and selected wordclock frequencies), check
the connections between the 02R units.
