Audio Out Settings
Audio Out Delay
With a Home Theatre System (HTS) connected to the
TV, the picture on TV and the sound from the HTS
should be synchronised.
Automatic audio to video sync
With recent Philips Home Theatre Systems, the audio
to video sync is done automatically and always
correct.
Audio sync delay
For some Home Theatre Systems you might need to
adjust the audio sync delay to synchronise the audio
to the video. On the HTS, increase the delay value
until there is a match between picture and sound. A
delay value of 180ms may be required. Read the user
manual of the HTS. With a delay value set up on the
HTS, you need to switch off Audio Out Delay on the
TV.
To switch off Audio Out Delay...
1 - Press  , select All Settings and press OK.
2 - Select Sound and press  (right) to enter the
menu.
3 - Select Advanced > Audio Out Delay and
press OK.
4 - Select Off.
5 - Press  (left) repeatedly if necessary, to close
the menu.
Audio Out Offset
If you cannot set a delay on the Home Theatre
System, you can set the TV to sync the sound. You
can set an offset that compensates for the time
necessary for the Home Theatre System to process
the sound of the TV picture. You can set the value in
steps of 5ms. Maximum setting is -60ms.
The Audio Out Delay setting should be switched on.
To synchronise the sound on the TV...

Audio Out Format
If you have a Home Theatre System (HTS)
with multichannel sound processing capabilities like
Dolby Digital, DTS® or similar, set the Audio Out
Format to Multichannel. With Multichannel, the TV
can send the compressed multichannel sound signal
from a TV channel or connected player to the Home
Theatre System. If you have a Home Theatre System
without multichannel sound processing, select Stereo.
To set Audio Out Format...
1 - Press  , select All Settings and press OK.
2 - Select Sound and press  (right) to enter the
menu.

the menu.
Audio Out Levelling
Use the Audio Out Levelling setting to level the
volume (loudness) of the TV and the Home Theatre
System when you switch over from one to another.
Volume differences can be caused by differences in
sound processing.
To level the difference in volume...
1 - Press  , select All Settings and press OK.
2 - Select Sound and press  (right) to enter the
menu.
3 - Select Advanced > Audio Out Levelling and
press OK.

5 - If the volume difference is large, select More. If
the volume difference is small, select Less.
6 - Press  (left) repeatedly if necessary, to close
the menu.
Audio Out Levelling affects both the Audio Out -
Optical and HDMI ARC sound signals.
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 Audio Out Format of
the TV to Stereo (uncompressed).
