Once this connection is made, the AVR80 will accept the digital output directly from your LD or CD player, no matter if any Surround mode is selected or pure Stereo mode. To select the direct digital input, press the LD button 7cand hold it for three seconds. This means that audio signals will remain in their pure digital state until after all surround processing or after the (only) D/A conversion in Stereo mode has taken place.

NOTE: This connection is for standard two channel 44.1 kHz PCM digital audio, as provided by LD or CD machines. It is NOT an input for multichannel digital audio signals such AC-3 or DTS. Improper connection to the wrong type of digital output may cause damage to the AVR80 or other components in your audio system and are not covered by the AVR80 warranty. Consult your dealer or installer if you have any questions about this input.

6 Channel Direct Operation Since 1993, an increasing number of theatrical motion pictures have been recorded with digital sound tracks. With these new processes such as Dolby Surround Digital™(AC-3), DTS® and Sony’s SDDS®, five or more discrete sound channels are available along with a dedicated subwoofer channel for low frequency sounds. The replacement of analog matrix theatrical audio, such as Dolby Stereo with these new systems has greatly increased the enjoyment of movie sound.

Advances in electronics technology now make it possible to bring these discrete digital audio soundtracks into your home. Many of today’s new LD players and an increasing number of LD movie releases provide for Dolby AC-3 Digital soundtracks. In the future, high definition television (HDTV) broadcasts will also carry multichannel digital audio information.

To prevent your AVR80 from obsolescence, special jacks are provided for use with external multichannel audio adapters.

If an adapter is installed in your system, connect its six analog audio outputs to the 6-CH DIRECT INPUT jacks ¿on the AVR80’s rear panel.

When listening to programs using an external adapter, press the 6-CH DIRECT button ï on the front panel. All surround processing will be disabled when 6 Channel Direct is in use, as none is required with discrete audio signals. Volume is controlled in the normal fashion.

NOTE: Audio reproduced from the 6 Channel Direct inputs may not be recorded via the AVR80.
