VAMS-0808
VIDEO AUDIO MATRIX SWITCHER
Unpacking
It is neither complicated to install nor difficult to operate your Video Audio Matrix Switcher. However, a few
minutes of your time are required to read this manual for a properly wired installation and to become
familiar with its many features. Please take great care in unpacking your set and do not discard the carton
and other packing. They may be needed if it ever becomes necessary to return your set for servicing. Never
place the unit near radiators, in front of heating vents, in direct sun light, in excessive humidity or dusty
locations so as to avoid early damage and to provide years of quality use. Connect your complimentary
components as illustrated in the following pages.

Definition
VAMS-0808 is a full matrix switcher which can represent 8 A/V inputs to any 8 A/V outputs simultaneous-
ly without any A/V thermal noise.
This machine includes microprocessor controller, so it’s easy to control and it allows to be displayed the
present setting at STATUS WINDOW DISPLAY.
Besides PC can control the matrix system by RS-232 communication interface.
In addition two VAMS-0808 may be cascaded for control via a signal port by configuring one VAMS-0808
as a MASTER.
RISK OF ELECTRIC SHOCK
DO NOT OPEN
CAUTION
CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK.
DO NOT REMOVE COVER (OR BACK).
NO USER-SERVICEABLE PARTS INSIDE.
REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.
WARNING
To prevent fire or shock hazard, do not
expose the unit to rain or moisture.
This symbol is intended to alert the user to the
presence of uninsulated “dangerous voltage”
within the product’s enclosure that may be of suf-
ficient magnitude to constitute a risk of electric
shock to persons.
This symbol is intended to alert the user to the
presence of important operation and mainte-
nance (servicing) instructions in the literature
accompanying the appliance.
Caution: To prevent electric shock do not use this (polarized) plug
with an extension cord, receptacle or other outlet unless
the blades can be fully inserted to prevent blade expo-
sure.
Attentions: Pour prévenir les chocs électriques ne pas utiliser cette
fiche polarisée avec un prolongateur, une prise de
courant on une autre sortie de courant, sauf si les
lames peuvent étre insérées à fond sans en laisser
aucune partie à découvert.

Using the Matrix
Using the Matrix
- POWERING THE MACHINE
Connect the AC CORD which is involved in the carton box with the “~AC INPUT” located on the rear of the
machine.
Plug the AC CORD to the power source (220V/60Hz or 230V/50Hz), then turn on the power switch
located on the front panel of VAMS-0808.
If the connection is correct, the green light of power switch will be turned on.
- USING THE CONTROL SWITCH OF THE FRONT PANEL
1. SELECTING AN OUTPUT
To select an output, press one of the number of OUTPUT switch button.
For example, to select output NO1, press output switch button NO1 of the front panel.
At this time, status display NO1 located on left of the front panel is blinked for 10 seconds approximate-
ly.
Like this, any outputs can be selected.
These buttons correspond to output connectors as marked on the rear panel of VAMS-0808.
2. SELECTING AN INPUT
To select an input, press one of the number of INPUT switch button.
For example, to indicate input NO1 to output NO1, press output switch button NO1 and select input
switch button NO1 when status display NO1 is blinked. Then the blinking of the status display is
stopped and input NO1 is selected.
These buttons correspond to input connectors as marked on the rear panel of the machine.
3. SELECTING A VIDEO
Only to control a video, press VIDEO switch button. Confirm that the green light of the video switch
button is turned on.
4. SELECTING A AUDIO
Only to control a audio, press AUDIO switch button. Confirm that the green light of the audio switch

6. USING THE ALL FUNCTION
To control all outputs simultaneously, press the ALL switch button.
For example, to display all output to input NO1, press the ALL switch button. Confirm that all status
display are blinked. After that, press input NO1. Then the blinking is stopped and all status display
indicate NO1.
7. USING THE OFF FUNCTION
VAMS-0808 has a function that disconnects each output or all outputs.
For example, To disconnect output NO1, Press the OUTPUT switch button NO1 and press the OFF
switch button when the status display NO1 is blinked.
Like this, to disconnect all outputs, press the ALL switch button. Then press the OFF switch button when all
status displays are blinked.
8. USING THE LOCK FUNCTION
VAMS-0808 has a LOCK function to preserve a configuration from user’s mishanding. To lock this
machine, press the LOCK switch button 5 times repeatedly, confirm that the green light of the LOCK
switch button is turned on. To recall the unit, press the LOCK switch button 5 times, confirm that the
green light of the LOCK switch button is turned off.
- USING THE CONTROL TERMINAL OF THE REAR PANEL
1. CONNECTING PARALLELLY WITH OTHER VAMS-0808 (MASTER AND SLAVE)
It allows to be controlled slave VAMS-0808 which is connected parallelly with master by external con-
nection jack. The operations of master affects them of slave equally.
First of all, Make the cable which can connect IN/OUT SELECT of the rear panel using 15P D-SUB jack
(figure 1).
After connecting two matrix systems with cable, confirm that the operation of MASTER and the operation
of SLAVE is the same when master is controlled.

2. PARALLEL CONNECTION
Two VAMS-0808 can be connected as two masters by connecting external jack each other. First of all,
Make the cable which can connect IN/OUT SELECT of the rear panel using 15P D-SUB jack (figure 2)
After connecting two matrix systems with cable, confirm that two VAMS-0808 operate as MASTER
which can control other machine.
3. CONNECTING WITH PC
It’s possible to control VAMS-0808 by PC with control program (RS-232C communication interface)
First of all, make the cable which can connect PC using 9P D-SUB jack. Then connect VAMS-0808 with
PC using the cable. And execute the control program in PC.
Confirm that the operation of PC and the operation of VAMS-0808 is the same when PC is controlled
