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 7c and
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.

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 ø on
the AVR80’s rear panel.
When listening to programs using
an external adapter, press the 6-CH
DIRECT button Ô 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.
