Audio Return Channel
Audio Return Channel features rely on CEC to work effectively. CEC is enabled through the
KD-Pro6x6/8x8CC matrix switcher.
ARC is supported by the HDMI Output ports only, NOT on the HDBaseT Output ports. The audio
return channel is not output via HDMI, but instead it is sent to the corresponding 3.5mm expansion
port of the output to which the ARC audio is connected to. A common 3.5mm stereo to L/R RCA
Y-cable may be used to connect to your AVR, however, the audio output signal will be PCM digital
and will only be carried on one of the RCA leads.
Example:
An ARC compatible display is connected to output 8. The audio will be sent to 3.5mm
expansion port number 8.

Using the KD-Pro6x6/8x8CC in a Compass Control project
›
Create a new Compass Control project
(Note: The below images depict KD-HD8x8Lite. Simply
select the desired KD-Pro6x6/8x8CC modules in the below steps as they become available in
Compass Navigator software.):
»
a. Select Custom or Modular.
»
b. Name the project.
»
c. Save the file in a different folder; rather than the default as displayed below.
›
Add the KD-ProCC unit as a Master controller
»
Assign the appropriate IP address and IP Port (corresponding with section)
