Sound Settings

AC3

The receiver has an audio output for the AC3 format (Dolby Digital) providing you with the opportunity of listening to cinema sound quality in your living room. Only connect the digital output with a correspond- ing system.

Please refer to the instruction manual of your Dolby Digital sys- tem.

Only a few programme providers broadcast the AC3 format. As long as no AC3 signal is received, you can only carry out the usual stereo and mono settings or select the transmitted language.

Switching off sound

Press the button on the remote control to mute the sound. This symbol appears on the screen.

Press the button again to restore the sound. The standard vol- ume display bar is then shown for several seconds.

You can change the programme while in mute mode, but the pro- gramme will remain muted until this mode is cancelled or you correct the volume.
