SAFETY INSTRUCTIONS
Every person involved with the installation, operation and maintenance of this system has to:
-be qualified
-follow the instructions of this manual
Before you initial start-up, please make sure that there is no damage caused by transportation. Should
there be any, consult your dealer and do not use the system.
To maintain perfect condition and to ensure a safe operation, it is absolutely necessary for the user to
follow the safety instructions and warning notes written in this manual.
Please consider that damages caused by manual modifications to the system are not subject to
warranty.
This system contains no user-serviceable parts. Refer servicing to qualified technicians only.
IMPORTANT:
The manufacturer will not accept liability for any resulting damages caused by the non-
observance of this manual or any unauthorized modification to the system.
Never let the power-cord come into contact with other cables! Handle the power-cord and all
connections with the mains with particular caution!
Never remove warning or informative labels from the unit.
Never use anything to cover the ground contact.
Do not connect this system to a dimmerpack.
CAUTION!

Do not switch the system on and off in short intervals, as this would reduce the system’s life.
Do not open the device and do not modify the device.
Only use system indoor, avoid contact with water or other liquids.
Avoid flames and do not put close to flammable liquids or gases.
Always disconnect power from the mains, when system is not used. Only handle the power-cord
by the plug. Never pull out the plug by tugging the power-cord.
Make sure you don’t use the wrong kind of cables or defective cables.
Make sure that the available voltage is not higher than stated on the rear panel.
Make sure that the power-cord is never crimped or damaged. Check the system and the power-
cord from time to time.
If you connect other parts of the system, be careful of ground loops.
Please read this manual carefully and keep it for future reference. Remember that the amplifier
has a better value on the market, if you save the carton and all packing materials.
Always operate the unit with the AC ground wire connected to the electrical system ground.
Do not drive the inputs with a signal level bigger, than required to drive the equipment to full
output.
Please turn off the power switch, when changing the power cord or signal cable.
If your Dap Audio device fails to work properly, discontinue use immediately. Pack the unit
securely (preferably in the original packing material), and return it to your Dap Audio dealer for
service.
Allow time to cool down, before cleaning or servicing.
For replacement use fuses of same type and rating only.
Prevent distortion! Make sure that all components connected to the device have sufficient power
ratings. Otherwise distortion will be generated because the components are operated at their
limits.
Avoid ground loops! Always be sure to connect the power amps and the mixing console to the
same electrical circuit to ensure the same phase!
If system is dropped or struck, disconnect mains power supply immediately. Have a qualified
engineer inspect for safety before operating.
If the system has been exposed to drastic temperature fluctuation (e.g. after transportation), do
not switch it on immediately. The arising condensation water might damage your system. Leave
the system switched off until it has reached room temperature.
This device falls under protection class I. Therefore it is essential to connect the yellow/green
conductor to earth.
Repairs, servicing and electric connection must be carried out by a qualified technician.

Description of the device
Features
The VDA-15 is a 1:5 Video/Audio Distributor. The VDA-15 is designed for the AV-studio or multimedia use
where high quality is required for distributing signals over longer distances. Outputs are independent from
each other. This way, overloading or even shorting one output will have no influence on the other outputs
performance.
When combining 3 units, audio can be distributed in 5.1 surround while video can be distributed in RGV
of YUV thus enabling the highest AV-quality available.
• Video and audio distribution amplifier
• 1 input, 1 loop output - 5 outputs

1. Power on switch.
This is the main Power switch. Press to turn the amplifier on.

2. DC/AC switch.
The DC/AC button controls the video input coupling. Pressing the DC button causes the video signal
input (as well as output) to be fully DC coupled. For example, the output signal follows the DC offset, if
it exists, and the button is released, the video input becomes AC coupled, removing the DC offset
from the input signal. To achieve the best linearity and signal fidelity, the signals should be DC
coupled. If input signals ride on a large DC offset (sometimes caused by the video source), release
the DC button to remove the DC offset.
3. Video EQ trimmer.
Use this trimmer to adjust the video EQ.
4. Audio L gain trimmer.
Use this trimmer to adjust the Left audio level if necessary.
5. Video in BNC connector.
Connect to the output of your video source.
6. Lo/Hi Impedance switch.
When using a VDA-15 standalone, select “Lo” (75Ω). If you want to loop several units using the Video
Loop (7) connector, select “Hi” for each unit connected to a video loop output.
7. Video Loop BNC connector.
Connect this output to the input of another VDA-15 if you need more than five video outputs. Make
sure that the Impedance switch (6) of the VDA-15 connected to the video Loop connector is set to
“Hi”.
8. Video gain trimmer.
Use this trimmer to adjust the video gain.
9. Video out 1 BNC connector.
Connect to the input of a video device.
10. Video out 2 BNC connector.

22. IEC Power Inlet and Fuse.
This connector is meant for the connection of the supplied main cord. Connect one end of the
power cord to the connector, the other end to the mains, then turn on the power switch (2) to
operate the unit.
Note: Please make sure that the supply voltage matches the operation voltage before connecting
the unit to mains. Replace the fuse only with a fuse of same specification (T500mA).
Installation
Remove all packing materials from the Antenna Distributer. Check that all foam and plastic padding is
removed.
Always disconnect from electric mains power supply before cleaning or servicing.
Damages caused by non-observance are not subject to warranty.
Set Up and Operation
Before plugging the unit in, always make sure that the power supply matches the product specification
voltage. Do not attempt to operate a 120V specification product on 230V power, or vice versa.

Maintenance
The DMT VDA-15 requires almost no maintenance. However, you should keep the unit clean.
Disconnect the mains power supply, and then wipe the cover with a damp cloth. Do not immerse in
liquid. Do not use alcohol or solvents.
Keep connections clean. Disconnect electric power, and then wipe the connections with a damp cloth.
Make sure connections are thoroughly dry before linking equipment or supplying electric power.
Replacing a Fuse
Power surges, short-circuit or inappropriate electrical power supply may cause a fuse to burn out. If the
fuse burns out, the product will not function whatsoever. If this happens, follow the directions below to do
so.
1. Unplug the unit from the electric power source.
2. Insert a flat-head screwdriver into a slot in the fuse cover. Gently pry up the fuse cover. The fuse will
come out.
3. Remove the broken fuse. If brown or unclear, it is burned out.
4. Insert the replacement fuse into the holder where the old fuse was. Reinsert the fuse cover.
Be sure to use a fuse of the same type and specification. See the product specification label for
details.
