PRODUCT OVERVIEW 

DVI Link DD-D12 and DD-D15, DVI Distribution Amplifiers, allow one digital video sources to be spilt 

into multiple digital displays. The built-in amplification function enables DVI signal distribution without 

signal loss. 

 

MAIN FEATURES 

1. 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.   

 

2. 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 amp 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.   

 

3 . 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.
