Connecting an analog audio system

This connection allows you to use external speakers with an external audio amplifier to adjust the sound level.

To control the audio:

Turn on the TV and the stereo amplifier.

Turn off the TV’s built-in speakers (see “Turning off the built-in speakers” on page 40.)

Note:

To hear sound when using an external audio amplifier, the volume of both the TV and the amplifier must be set to a reasonable listening level.

Connecting a digital audio system with built-in digital surround

The TV’s two digital audio outputs output a Dolby Digital or 2-channel down-mixed PCM (pulse-code

modulation) signal for use with an external Dolby Digital decoder or other external audio system with optical or coaxial audio input.

Note:

Refer to the Owner’s manual of the audio amplifier as well.

The COAXIAL DIGITAL AUDIO OUT jack outputs digital audio only during digital broadcasts with digital audio. To hear analog broadcast audio, you also must connect analog audio cables from the L/R ANALOG AUDIO jacks to the receiver’s inputs.

Consult the owner’s manual for your receiver to determine the best way to switch between the analog and digital signals.
