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 DVI signal will need to travel is over 10ft. Due to the nature of
DVI 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 DVI extenders
or cables.
Support HDMI v1.3
The DD-250 is fully compatible with HDMI version 1.3
HDCP (High-bandwidth Digital Content Protection) Compliant
PureLink’s DVI 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, DVI Switch, Distribution Amplifier, etc.) is required.
