Main Features
High Quality Picture - No Signal Loss and Digital Noise Free
Our Distribution Amplifiers are built to deliver the highest quality picture preserving the
native resolutions of the video sources without any signal loss. At the same time, the
digital noises that may affect the picture quality will be eliminated. Due to the nature of
the digital signals and passing through multiple stages of connection when using
distribution amplifiers, it is important to eliminate the digital noises and boost the signal
strength to preserve/enhance the video signal quality.
Signal Amplification for signal reliability and long length signal
transmission.
Our 5V power adapter supplies adequate power to amplify the video signals from the
video source. This is necessary as the overall length from the video source to the
displays is longer when using the distribution amplifiers(distance from the video source
to the distribution amplifier + distance from the distribution amplifier to the display). In
most cases, the overall distance that the DVI signal will need to travel is over 10ft. Due
to the nature of DVI signals, amplification is necessary to warrant the video quality and
reliability. (Without amplification, there may be occasional blackouts or blinking effects)
With this amplification feature, your video display can be extended up to 2300ft using
our fiber optical DVI cables.
HDCP(High-bandwidth Digital Content Protection) Compliant
Our DVI distribution amplifiers are fully HDCP compliant. Many video sources such as
DVD players and Satellite/Cable Receivers are HDCP encrypted. For these video
sources to be displayed correctly, HDCP compliant devices(e.g., TV, DVI Switch,
distribution amplifier) are required.
1-4 Main Features

Video Connection
1. Connect your video source’s DVI output port to the DD-D12/D15’s DVI input port
using standard DVI cables(not included). Make sure all your DVI source and the
displays are turned off before connecting the cables.
2. Connect your DVI display’s DVI input port to DD-D12/D15’s DVI output port. Make
sure your DVI display is turned off before connecting the cables.
3. Plug the 5V power supply into the switch’s power input port.
4. Plug the 5V wall mount power supply into the wall outlet.
5. Turn on your displays.
6. Turn on your video source.
DDC On/Off Switch
DD-D12/D15 are equipped with DDC on/off dip switches in the back for each DVI
output port. DDC communication is required for some video sources and
displays(such as PC and LCD monitor) to correctly display the picture. In most cases,
you will not need to change the factory settings.
When the DDC is turned on for both DVI output ports, some video source may not
work correctly as it sees multiple (conflicting) DDC information. Please turn on DDC
for the video display you would like the video source to recognize as the default
display and at the same time, turn off DDC for all other DVI out ports. In such case,
other DVI ports will transmit video according to the default display setting (DVI port
with DDC turned on)
