If your player has this type of output,
connect the LD player to the AVI250 with
a high quality digital interconnect (110
ohm cable with RCA plugs). The
connection should be made to the 

jack 

S

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

7c

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 system
and are not covered by the product
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

™

, 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 AVI250 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 

jacks 

∆

on

the AVI250’s rear panel.

When listening to programs using an
external adapter, press the 

button 

*

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 6 Channel
Direct inputs may not be recorded.
