4 or 8 Channel Splitter PC Video, Audio & RS232 over Twisted-Pair Receivers 3. Configuration & Operation 3.1 Why Cable Compensation? All cables attenuate (reduce) the high-frequency components of the video signal that is being transmitted. The longer the cable, the more signal loss. If not compensated for, this signal loss will result in blurry and smeared images being displayed.
