Setting up a digital audio connection
You can connect the TV to an external amplifier, receiver, or sound bar by using either of these
two connections:
HDMI ARC – The HDMI
®
Audio Return Channel enables the TV to output digital
audio on one of its HDMI
®
connectors. The connected amplifier can also
function simultaneously as an input source to the TV, if needed. To use the
ARC capability, you must connect an HDMI
®
cable from your amplifier’s HDMI
®
ARC
connector to the HDMI ARC connector on the TV. You also must:
o Be sure your HDMI
®
cable is certified by HDMI
®
.
o Enable HDMI ARC under Settings > System > Control other devices (CEC), as
explained in Enable HDMI
®
ARC.
SPDIF optical – The TV has an SPDIF optical connector that outputs a digital
audio signal. To use the optical output, connect a TOSLINK optical cable
from the amplifier to the Optical or SPDIF connector on the TV.
Note: Dolby Audio™ supporting Dolby Digital Plus™ format is not available through the
SPDIF optical output. This format is only available through the HDMI
®
ARC connection.
After making the required HDMI
®
ARC or SPDIF optical connection, go to Settings > Audio >
S/PDIF and ARC option and select the audio format to use.
Note: In most cases, Auto detect is the best option. Other settings can result in no sound when
the content you are viewing does not contain the audio stream type you selected.
Controlling other devices through CEC
Consumer Electronics Control (CEC) enables your TV and other CEC-compatible home
entertainment devices to control one another in various ways. First, the CEC-compatible
devices must “discover” one another and report their capabilities. After this, one device can
control another according to the features you enable. For example, playing a disc on a Blu-ray™
player could switch the TV to the Blu-ray™ player’s input. Or, powering off the TV could also
power off the Blu-ray™ player and the home theater receiver.
