ohm cable with RCA plugs). The connec-
tion should be made to the LD DIGITAL
IN jack KY on the rear panel.
Once this connection is made, the AVI250
will accept a PCM digital audio output
directly from your LD player. This means
that audio signals will remain in their
pure digital state until after all surround
processing has taken place. To select the
direct digital input, press the LD button
E4@> and hold it for three seconds.
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 AVI250
or other components in your audio sys-
tem and are not covered by the product
warranty. Consult your dealer or installer
ifyou 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’ DTS°® and Sony's
SDDS® five or more discrete sound
channels are available along with a dedi-
cated subwoofer channel for low frequen-
cy sounds. The replacement of analog
matrix theatrical audio, such as Dolby
Stereo, with these new systems has great-
ly 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 defini-
tion television (HDTV) broadcasts will
also carry multichannel digital audio
information.
To prevent your AVI250 from obsoles-
cence, 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 AVI250’s rear panel.
When listening to programs using an
external adapter, press the 6-CH
DIRECT button ff 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 fash-
ion.
NOTE: Audio reproduced from 6 Channel
Direct inputs may not be recorded.
