DL-UHDRC70 Quick Guide

The DigitaLinx DL-UHDRC70 is an HDBaseT extender that can extend uncompressed 

4K  video  at  a  maximum  of  3840x2160@60Hz/4:2:0,  multichannel  audio,  bi-

directional POC power, RS232 and bi-directional IR up to 40 meters (~130’) using a 

single Category 6 twisted pair cable. At 1080p@60Hz/4:4:4 the unit can extend up 

to 70 meters (~230’). 

Some select standard cable boxes that have sub versions of HDMI 1.2/1.3 chipsets 

that do not support clock stretching which is an integral part of the HDCP handshake. 

This  can  cause  transmission  issues  when  using  traditional  HDBaseT  extenders.                                                    

The  DL-UHDRC70  features  an  embedded  circuit  that  addresses  and  solves  HDMI 

clock  stretching  issues  that  are  common  in  older  cable  set  top  boxes  with  older 

HDMI chipsets. 

The DL-UHDRC70 is sold only as a set. The individual transmitter and receiver are not

compatible with other HDBaseT devices due to proprietary PoE circuitry.
