• S/PDIF optical – The 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.
• Auto detect – Automatically detects the incoming audio format and transcodes it
to a compatible available format for the audio output (ARC, eARC, or S/PDIF).
• Auto passthrough – Passes through the input audio to the connected receiver
without transcoding, sometimes resulting in better audio quality especially for
high-end audio formats such as those that take advantage of the higher
bandwidth of eARC, including Dolby MAT and Dolby Digital Plus 7.1, among
others.
