FUNCTIONS
Setup of the VR800
1 .Set the VR800 digital input track to [AdAt] and the digital in clock to [ASYnC](Asynchronous mode).
2 .Set the VR800 digital output track to [AdAt].
Note: Be sure to switch off power to the VC-8 at setup of the various selector switches. Should the switches be
manipulated with power switched on, noise could be created and the VC-8 may not function correctly.
Setup of the VC-8
Note: Refer to the VR800 Owner’s Manual for setups of the VR800 “Digital input track” and “Digital output track”
settings.
1 .Set the DIGITAL MODE switch to [ADAT].
2 .Set the ANALOG INPUT switch to [1-8].
If it is to be connected to a 4 BUS or 2 BUS mixer,
refer to next page.
3 .Set the CLOCK switch to [WORD].
4 .Switch ON the terminating switch.
5 .Switch on power to the VC-8.
At this stage, as signals are being input to both
DATA IN and WORD IN, the LOCKED LED will be lit
in orange color.
<The CLOCK switch and LOCKED LED>
The CLOCK switch is for selecting the required clock frequency and is selected in accordance to the application
as lited below. Depending on the application, the LOCKED LED indicates the type of digital signal that is
input and setting of the CLOCK switch.

If the LOCKED LED is lit in green,
the VC-8 will operate in sync with
the digital signal input to the VC-8
DATA IN connector. If the LOCKED
LED is extinguished, it indicates that
no digital signal is being input and
it will not operate correctly even
though switched to OPTICAL. In
such case, set the CLOCK switch
to INT. If the LOCKED LED is lit in red or
orange, the VC-8 will operate in
sync with the word clock that is in-
put to the VC-8 WORD IN connec-
tor. If the LOCKED LED is lit in
green or is extinguished, it is an in-
dication that word clock is not be-
ing input and thus will not operate
correctly even though the CLOCK
switch is set to WORD. In such
case, set the CLOCK switch to
OPTICAL or INT. Regardless to the LOCKED LED
indication, the VC-8 will operate
by its internal 44.1 kHz crystal.
