Audio Return Channel (ARC)
In some setups, it is desirable to use the TV as the source of audio. This is most common when watching
live terrestrial TV from an HD antenna. In this case, the TV is receiving a live ATSC signal over-the-air. The
video is shown on screen, but the user would like the audio to be played from the AVR (red path).
In most cases, the preference is for audio to be routed from the Quick
6
HDMI or MHL inputs to the Aux
HDMI output or to the S/PDIF output, and ARC is only used when viewing over-the-air broadcasts.
Most TVs can be put into Automatic ARC mode so that when they sense that an audio receiver capable of
receiving ARC is connected they automatically negotiate with the receiver to establish an ARC channel.
Audio Return Channel
Quick
6
has a special control mechanism to allow the user to easily switch ARC on and off; to use ARC with a
Quick
6
system:
1. Insure that your TV is capable of ARC and that the correct TV HDMI input (usually marked ARC) is
connected to the Quick
6
MAIN HDMI output.
2. Put the TV into ARC-on mode and turn on CEC (note that these two menu items will be labeled
differently by manufacturer – refer to the TV user’s manual for more information)
3. Connect an audio receiver from Quick
6
S/PDIF output (either coax or optical) to the receiver S/PDIF input
4. Switch the receiver to the S/PDIF input source
5. Either – press the ARC button on the Quick
6
remote control – OR on the Quick
6
On screen menu, under
advanced settings, select Enable ARC
Note that you can enable or disable ARC with the On-screen display. The ARC button on the remote control
toggles between enabling and disabling ARC mode.
Normally, the TV is left in ARC-on and CEC enabled mode and when the user wants to use ARC, simply
switch the audio receiver to S/PDIF input and press the ARC button on the Quick
6
remote.
