■ MOVIE THEATER 1 and 2
Most commercially available movie software has 4-channel (left, center, right and surround) sound information encoded
by Dolby Surround matrix processing and stored on the left and right tracks. These signals are processed by the Dolby
Pro Logic decoder. The MOVIE THEATER programs are designed to recreate the spaciousness and delicate nuances of
sound that tend to be lost in the encoding and decoding processes.
The 6-channel soundtracks found on 70-mm film produce precise sound field localization and rich, deep sound without
using matrix processing. This unit’s MOVIE THEATER 70 mm programs provide the same quality of sound and sound
localization that 6-channel soundtracks do.
When the input source is analog, PCM or encoded with Dolby Digital in 2-channel
These programs express an immense sound field and a
large surround effect. They also give depth to the sound
from the main speakers to recreate the realistic sound of a
Dolby Stereo theater.

70 mm GENERAL
The built-in Dolby Digital or DTS decoder brings the professional-quality sound designed for movie theaters into your
home. With the unit’s MOVIE THEATER programs, you can recreate a dynamic sound that gives you the feeling of
being at a public theater in your listening room by using Dolby Digital or DTS technology.
When the input source is encoded with Dolby Digital (5.1-channel) or DTS (Tri-Field CINEMA DSP)
These programs use YAMAHA’s tri-field DSP processing
on each of the Dolby Digital or DTS signals for the front,
left surround and right surround channels. This
processing enables this unit to reproduce the immense
sound field and surround expression of a Dolby Digital-
or DTS-equipped movie theater without sacrificing the
clear separation of all channels.
