Main Features
High Quality Picture - No Signal Loss / Digital Noise Free
PureLink’s 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 noise
that may affect the picture quality will also be eliminated. Due to the nature of the digital signals
and passage through multiple stages of connection when using distribution amplifiers, it is
important to eliminate the digital noise and boost the signal strength to preserve and enhance the
video signal quality.
Signal Amplification for reliability and long-length signal transmission
PureLink’s 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 HDMI signal will need to travel is over 10ft. Due to the nature of HDMI signals,
amplification is necessary to ensure 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 optic HDMI extenders or cables.
HDMI (High-Definition Multimedia Interface) v1.3
The HD-250 is fully compatible with HDMI version 1.3 and it can also be used for DVI
applications by using additional DVI to HDMI coupler or cable.
HDCP (High-bandwidth Digital Content Protection) Compliant
PureLink’s HDMI distribution amplifiers are fully HDCP compliant. Many video sources such as
Blu-ray DVD players and Satellite/Cable Receivers are HDCP encrypted to protect the copyrights
of those who created it. For these video sources to be displayed correctly, an HDCP compliant
device (e.g., TV, HDMI Switch, Distribution Amplifier, etc.) is required.

occurs:
Internal EDID Programming:
1. Press MENU button twice or more to find the appropriate EDID data for your application,
and then press the ENTER button to confirm the change.

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 a copper based HDMI 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 optic HDMI
extension cables such as the Purelink HDX II series
3. Use high quality HDMI 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 HDMI connectors are tightly secured to all HDMI
ports. Loosened screws on the HDMI connectors will result in no or
poor picture.
6. Turn off all equipment (video source, switch and HDTV) and
restart all equipment.
Incorrectly sized picture
/resolution or No picture
Please remember that your video source will only transmit one
resolution setting. To connect varying resolution displays
(1920x1200 resolution display and 1024 x 768 resolution display)
the resolution setting of your video source must be set to the lowest
resolution setting (1024 x 768).
