cables.
To use the ARC or eARC capability, you must connect an HDMI
®
cable from your amplifier’s
HDMI
®
ARC or eARC connector to the HDMI ARC or HDMI eARC connector on the TV. You
also must do the following:
Be sure your HDMI
®
cable is HDMI
®
certified.
Enable HDMI ARC under Settings > System > Control other devices (CEC), as
explained in Enable HDMI
®
ARC.
S/PDIF opticalThe S/PDIF optical connector outputs a digital audio signal. To use
the optical output, connect a TOSLINK optical cable from the amplifier to the
Optical or S/PDIF connector on the TV.
Important: To make sure the S/PDIF outputs audio reliably, you must turn off the TV’s speakers.
To do so, from the Home screen menu, navigate to Settings > Audio > Speakers and change
the setting to Off.
Note: Dolby Audio™ support for Dolby Digital Plus™ format is not available through the S/ PDIF
optical output. This format is only available through the HDMI ARC connection.
Tip: Even when you use S/PDIF for audio, the TV can correctly detect more audio formats if you
connect an HDMI
®
cable between the TV’s HDMI ARC or HDMI eARC port and the receiver’s
ARC or eARC port.
Choosing an audio format
After making the required HDMI
®
ARC, eARC, or S/PDIF optical connection, go to Settings > Audio >
S/PDIF and ARC option and select the audio format to use.
Choosing Auto detect is the easy solution, and generally provides good results. However, if you have a
high-end sound system and want to make sure you are getting the best sound quality available in the
programs you are watching, you can choose another setting.
