Alternatively, you can use a SCART cable if the device has no HDMI connection.

HDMI ARC

If your Home Theatre System has an HDMI ARC connection, you can use any HDMI connection on the TV to connect. All HDMI connections on the TV can offer the Audio Return Channel (ARC) signal. But once you connected the Home Theatre System, the TV can only send the ARC signal to this HDMI connection.

With HDMI ARC, you do not need to connect the extra audio cable. The HDMI ARC connection combines both signals.

If the Home Theatre System has no HDMI ARC connection, add an optical audio cable to send the sound of the TV picture to the Home Theatre System.

Audio to video synchronisation (sync)

If the sound does not match the video on screen, you can set a delay on most DVD Home Theatre Systems to match the sound and video. A mismatch can be visible in scenes with people talking. When they finish sentences before their lips stop moving.

In Help, press *List and look up Audio to video sync for more information.

Audio to video sync

With a Home Theatre System (HTS) connected to the TV, the picture on TV and the sound from the HTS should be synchronised. A mismatch can be visible in scenes with people talking - when they finish sentences before their lips stop moving or just the opposite.

Automatic audio to video sync

With recent Philips Home Theatre Systems, the audio to video sync is automatically synchronised and always correct.

Setting up / Connect devices

For some Home Theatre Systems you might need to adjust the audio sync delay to synchronise the audio to 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, press hand select S Setup and press OK.

Select TV settings > Sound > Audio Out delay. Select Off and press OK.

Audio Out Offset

If you cannot set a delay on the Home Theatre System, you can set the TV to sync the sound.

To synchronize the sound on the TV, press hand select S Setup and press OK.

Select TV settings > Sound > Audio Out offset. Use the slider bar to set the sound offset and press OK. The value set compensates the time necessary for the Home Theatre System to process the sound of the TV picture. You can set the offset in steps of 5ms. Maximum setting is -60ms. The Audio Out delay setting should be switched on.

Audio Out Settings

Audio Out format

The standard setting for Audio Out format is Multichannel. Home Theatre Systems with multichannel sound capabilities (Dolby Digital, DTS® or similar) can receive a compressed multichannel sound signal from a TV channel or a connected disc player.

To set the Audio Out format, press hand select S Setup and press OK.

Select TV settings > Sound > Audio Out format.

If you have a Home Theatre System without any multichannel sound processing capabilities, select Stereo.

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, press hand select S Setup and press OK.

Select TV settings > Sound > Audio Out levelling.

If the volume difference is large, select More. If the volume difference is small, select Less.

Audio Out levelling affects both the Audio Out - Optical and HDMI-ARC sound signals.
