5. System Connection
The following diagram illustrates the typical input and output connections of the
extender:
1) The ARC mode of receiver is ON, and the display device (e.g. HDTV) supports
ARC. The TV audio is transmitted from the TV back to the receiver via HDMI
cable, and then it will be output by the ARC Audio Out port of transmitter.
Note: The STP cable is recommended to be used to ensure optimal machine
performance in ARC mode.
