Home Theatre System - HTS
Connect with HDMI ARC/eARC
Use an HDMI cable to connect a Home Theatre
System (HTS) to the TV. You can connect a Philips
Soundbar or an HTS with a built-in disc player.
HDMI ARC
All HDMI connections on the TV can offer the Audio
Return Channel (ARC) signal. But once you have
connected the Home Theatre System, the TV can
only send the ARC signal to this HDMI connection.
If your Home Theatre System has an HDMI ARC
connection, you can use any HDMI connection on the
TV to connect. With HDMI ARC, you do not need to
connect the extra audio cable. The HDMI ARC
connection combines both signals.
HDMI eARC
HDMI eARC (Enhanced Audio Return Channel) is an
advancement over the previous ARC. It supports the
latest high-bitrate audio formats up to192kHz, 24-bit,
and uncompressed 5.1 and 7.1, and 32-channel
uncompressed audio. HDMI eARC is only available on
HDMI 2.
Audio to video synchronisation (sync)
If the sound does not match the video on screen, you
can set a delay on most Home Theatre Systems with
a disc player to match the sound with the video.
Problems with HTS sound
Sound with loud noise
If you watch a video from a plugged in USB flash drive
or connected computer, the sound from your Home
Theatre System might be distorted. This noise is heard
when the audio or video file has DTS sound but the
Home Theatre System has no DTS sound processing.
You can fix this by setting the Digital Out Format of
the TV to Stereo.
Select Settings > Display & Sound > Audio out
> Digital out format.
No sound
If you cannot hear the sound from the TV on your
Home Theatre System, check if you connected the
HDMI cable to an HDMI ARC/eARC connection on
the Home Theatre System. All HDMI connections on
the TV are HDMI ARC connections. HDMI eARC is
only available on HDMI 2.
9.3
Digital Audio Out - Optical
Audio Out - Optical is a high quality sound
connection.
This optical connection can carry 5.1 audio channels.
If your device, typically a Home Theatre System
(HTS), has no HDMI ARC connection, you can use this
connection with the Audio In - Optical connection on
the HTS. The Audio Out - Optical connection sends
the sound from the TV to the HTS.
