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.
