Choosing An Audio Format - Philips 24PFL4764/F7 User Manual

• 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
eARC port and the receiver's ARC or eARC port.

Choosing an audio format

After making the required HDMI
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.
