Choosing the digital audio output mode

You must be watching a digital TV channel to access the Audio menu Digital Audio option. This option sets the format for the signal provided on the Digital (Optical) Audio Output connector on the rear of the TV: Dolby Digital or PCM. Select PCM if your external digital audio system does not support surround sound. See “Understanding audio output” on page 32.

Selecting virtual surround sound

You can enjoy emulated surround sound from the TV speakers. To do so, in the Audio menu Virtual Surround option select the mode that you want to hear: Theater or Music Hall.

Understanding audio output

The input source signal and the Audio menu settings for Digital Audio and Speaker determine the type of audio output that you hear at the speakers, or at the external sound system connected to the TV.

For example, if you connect an external sound system by using the Digital (Optical) connector, you hear digital sound from the connected external audio system when you watch a digital TV program. The format of digital signal that the TV provides depends on the Digital Audio setting (Dolby Digital or PCM).

This TV does not support Dolby Digital audio input over HDMI. When connecting a set-top box, DVD player, or other device by means of HDMI, set the device audio output to PCM format.
