Model VC-8 Owner’s Manual
INTRODUCTION
Thank you very much for having purchased the Fostex Model VC-8.
The VC-8 is an adat/analog converter which allows connections to be made with adat optical exclusive
digital multirecorder such as the VR-800 and various analog mixers. In order to accomplish high
quality collaboration with analog mixers, the professional 20 bit type are employed for AD/DA.
Also, to build a most effective system matched with the number of analog mixer output BUSes (2 BUS
OUT, 4 BUS OUT, 8 BUS OUT) the INPUT MODE switch makes it unnecessary to reconnect the cables
at record/playback. Furthermore, the VC-8 can be used as a S/P DIF/analog converter, and by
connecting to the sound card contained in various computers with digital input/output, it will give
a clean record/playback environment free of internal noise generated in the computer.
Before operating VC-8, it is recommended to thoroughly read this manual to insure long life of this
equipment.
Precautions (please read before use)
Outstanding Features
Power supply
* A digital multiple system can be setup by using
the adat optical and analog in/out converter of
the VC-8 together with various analog and digital
mixers provided with adat optical such as the
VR800.
* When unplugging the AC adaptor from the outlet,
be sure to grasp the adaptor. Attempting to unplug
it by pulling on the AC cable may damage the
wiring.
* It is dangerous to use any power cable that is cut
or frayed. If the power cable is damaged,
immediately stop using it, and have it repaired.
* Due to employ of the professional 20 bit AD/DA
converter, it is possible in conjunctive operation
with the analog mixer without degrading the high
quality sound of digital recordings.
* Do not plug in or unplug the AC adaptor with wet
hands. Doing so may result in dangerous electric
shock.
* As the INPUT MODE is switchable, it is possible to
construct a system to match the number of BUSSes
in the analog mixer.
* Do not open the unit or touch any parts inside.
Doing so may result in a dangerous electric shock,
and could damage the unit.
* Additionally, as S/P DIF can be converted to the
analog inputs/outputs and vice versa, it can be
connected to the internal sound card of the
computer provided with digital inputs/outputs.
* Do not let water or other liquids, flammable
materials, or metal objects such as pins get inside
the unit. These things may cause electrical shock
or short circuit the VC-8, and damage it.
If the VC-8 should become wet, unplug the AC
adaptor from the AC outlet, and contact your
authorized service station.
* Either the internal (44.1kHz) or OPTICAL/WORD
(Phase adjusting range: 32~48kHz) can be selected
and thus it can be widely adapted to digital
equipment.
Location
* Avoid using the VC-8 in the following locations:
* Locations of extreme low or high temperatures, or
extreme changes in temperature.
* Locations with excessive moisture or dust.
* Locations where direct sunlight falls for an
extended time, or near a stove or other source of
heat.
* Locations where electrical voltage varies.
* Unstable locations or where there is heavy
vibration.
* Near strong magnetic fields (on top of a television
or speaker).

Names and Functions
ANALOG INPUT MODE switch
This switch is used to select the
channel to which the ADAT output
should be assigned for the signal
input to the ANALOG INPUT jack.
This switch will be active only when
the DIGITAL MODE switch is set to
ADAT. Refer to pages 6 and 7 for
details.
POWER switch/POWER LED
AC power to the VC-8 is switched
ON/OFF (or “standby”). If the VC-
8 is not to used for a long period,
the AC adaptor should be
unplugged from the wall AC mains.

Connecting Examples
Example at operating it as the ADAT-ANALOG converter
The following connecting schematic is an example of locating the VC-8 between an analog mixer
with 8 TAPE IN - 8 BUS OUT (or GROUP OUT) and the VR800 (digital multitrack recorder). In this
system, the 8 BUS output from the analog mixer is converted to adat digital signals and the signals of
channels 1~8 can be recorded on tracks 1~8 of the VR800.

Note: When the digital inputs and outputs of the VC-8 and VR800 (or another digital recorder) are connected
as shown in above connecting schematic, be sure to set one side as the clock master and the other as the
clock slave.
In other words, if the VC-8 had been set as the master, then VR800 (or another digital recorder) must be set
as the slave, or if in the reverse situation whereas VC-8 had been set as the slave, then VR800 (or another
digital recorder) must be set as the master. The most recommended setting at using the VC-8 is to establish
the digital recorder as the master and the VC-8 as the slave as shown in table below.
VR800: Asynchronous mode
Other recorder: Internal mode
VR800: Synchronous mode
Other recorder: External mode
The most recommended setting. Furthermore, if the
WORD clock can be input, then WORD must be input.

When connecting a 4 BUS OUT mixer
Connect the mixer BUS OUT to INPUT 1~4 of the VC-8 and select [1-4] of the VC-8 ANALOG INPUT MODE
switch. Signals input to ANALOG IN 1~4 will be assigned, respectively, to ADAT outputs 1~4 and 5~8.
In other words, the ANALOG IN 1~4 signals will be simultaneously sent to tracks 1~4 and 5~8, thus 4
tracks each can be recorded without re-connecting the cables.

Example at operating it as the S/P DIF-ANALOG converter
The following is a connecting example of using the VC-8 as a S/P DIF-ANALOG converter which
makes it possible to extract sound from CD and DVD with the sound card contained in the computer
with S/P DIF digital output. By separating the analog circuit from the computer, this system can
playback (or record) a clear sound free of noise created in the computer.
