VPI MTX-4X4-CVA User manual

SAFETY INFORMATION
1. To ensure the best results from this product, please read this manual and all other documentation before operating your equipment.
Retain all documentation for future reference.
2. Follow all instructions printed on unit chassis for proper operation.
3. To reduce the risk of fire, do not spill water or other liquids into or on the unit, or operate the unit while standing in liquid.
4. Make sure power outlets conform to the power requirements listed on the back of the unit. Keep unit protected from rain, water and
excessive moisture.
5. Do not attempt to clean the unit with chemical solvents or aerosol cleaners, as this may damage the unit. Dust with a clean dry cloth.
6. Do not use the unit if the electrical power cord is frayed or broken. The power supply cords should be routed so that they are not
likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords and plugs, convenience
receptacles, and the point where they exit from the appliance.
7. Do not force switched or external connections in any way. They should all connect easily, without needing to be forced.
8. Always operate the unit with the AC ground wire connected to the electrical system ground. Precautions should be taken so that the
means of grounding of a piece of equipment is not defeated.
9. AC voltage must be correct and the same as that printed on the rear of the unit. Damage caused by connection to improper AC
voltage is not covered by any warranty.
10. Turn power off and disconnect unit fromAC current before making connections.
11. Never hold a power switch in the “ON” position.
12. This unit should be installed in a cool dry place, away from sources of excessive heat, vibration, dust, moisture and cold. Do not use
the unit near stoves, heat registers, radiators, or other heat producing devices.
13. Do not block fan intake or exhaust ports. Do not operate equipment on a surface or in an environment which may impede the normal
flow of air around the unit, such as a bed, rug, carpet, or completely enclosed rack. If the unit is used in an extremely dusty or smoky
environment, the unit should be periodically “blown free” of foreign dust and matter.
14. To reduce the risk of electric shock, do not remove the cover. There are no user serviceable parts inside. Refer all servicing to
qualified service personnel. There are no user serviceable parts inside.
15. When moving the unit, disconnect input ports first, then remove the power cable; finally, disconnect the interconnecting cables to
other devices.
16. Do not drive the inputs with a signal level greater than that required to drive equipment to full output.
17. The equipment power cord should be unplugged from the outlet when left unused for a long period of time.
18. Save the carton and packing material even if the equipment has arrived in good condition. Should you ever need to ship the unit,
use only the original factory packing.
19. Service Information Equipment should be serviced by qualifier service personnel when:
A. The power supply cord or the plug has been damaged.
B. Objects have fallen, or liquid has been spilled into the equipment.
C. The equipment has been exposed to rain
D. The equipment does not appear to operate normally, or exhibits a marked change in performance
E. The equipment has been dropped, or the enclosure damaged.

INTRODUCTION
INTRODUCTION
Congratulations on your purchase of one of the most innovative Video/Audio switching products on the market today. The Switcher is
a true Matrix Routing Switcher for Composite Video and Stereo Audio signals. It has 4 individual AV inputs with 4 individual AV outputs.
Because it is a matrix router, any input may be routed to any output; or the same input may be routed to all outputs or any combination.
It completely eliminates the need to constantly move around audio and video input and output cables. The Switcheris useful for routing
signals from AV source devices (such as: VCRs, Camcorders, Video Game Consoles, Video CDs, DVDs, Satellite Receivers, CAT5 Set
Top Boxes, etc .) toAV destination devices (such as: VCRs, DVD-Rs, TV Sets, Video Projectors, etc.). Selection of inputs is made via the
Front Panel push buttons or an Infrared Remote Control unit.
Before you make any connections
Make sure all AV devices to be connected to the Matrix Routing Switcher are functioning according to their respective operation
manuals before connecting them . Always connect the AV devices to the Switcher one at a time and make sure each works just as it did
before it was connected.
Supplied Accessories
Check that you have the following components in your converter pack;
(1) 1 Instruction Manual
(2) 1 MTX-4X4-CVA Switcher
(3) IR Remote control
(4) 3-RCA to 3-RCA cable
(5) 1 AC Adaptor: 12VDC, 500ma
Safety Notice!
To prevent damage to your television equipment use only the supplied
AC Adaptor and make the power connections to your television
CAUTION
RISK OF ELECTRIC SHOCK
DO NOT OPEN
CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK,
DO NOT REMOVE COVER (OR BACK),
NO USER SERVICEABLE PARTS INSIDE,
REFER SERVICING TO QUALIFIED SERVICE PERSONAL.
WARNING!
TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK
DO NOT EXPOSE THIS EQUIPMENT TO RAIN OR MOISTURE.
This symbol is intended to alert the user to the presence of non-insulated
“dangerous voltage” within the products enclosure that may be of sufficient
magnitude to constitute a risk of electric shock to persons.
This symbol is intended to alert the user to the presence of important operational
and maintenance (serving) instructions in the literature accompanying the
appliance.
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
exposure. To prevent electric shock, match wide blade of plug to wide slot, fully
insert.
