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 12V 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.

** What is EDID?
Extended Display Identification Data is a VESA standard data format that contains basic
information about a display and its capabilities, including vendor information, maximum
resolution, color characteristics, factory pre-set timings, frequency range limits, and
character strings for the monitor name and serial number

Troubleshooting
Problem
Solution
Distribution Amplifier does
not operate
Make sure the 12V power is plugged in the back of the unit.
Check to see if the power LED light is on.
No picture(or signal)
Or Poor picture
1. In case your video source is HDCP enabled, make sure
your video display(HDTV) is HDCP compliant.
2. If you are using copper based DVI cable, overall length of
the cables (length of the cable from video source to switch
and length of the cable from switch to display) should not
exceed 20ft. Exceeding 20ft. with copper based cables will
result in no or poor picture quality. To extend beyond 20ft,
please use fiber optical DVI extension cables such as
Purelink OC series.
3. Use high quality DVI cables.
4. If you are using computers, try other refresh rate settings.
Most HDTV’s have refresh rate of 48Hz and computer’s video
cards are usually set at higher refresh rate. Try lower refresh
rates.
5. Make sure all DVI connectors are tightly secured to all DVI
ports. Loosened screws on the DVI connectors will result in
no or poor picture.
6. Turn off all equipments (video source, switch and HDTV)
and restart all equipments.
Incorrectly sized picture
/resolution or No picture
Please remember that your video source will only transmit
one resolution setting. To connect varying resolution displays
(1600x1200 resolution display and 800x600 resolution
display) the resolution setting of your video source must be
set to the lowest resolution setting (800x600).
