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 programs provide the same quality of sound and sound
localization that 6-channel soundtracks do. The built-in Dolby Digital or DTS decoder brings the professional-quality
sound designed for movie theaters into your home. With this unit's MOVIE THEATER programs, you can use Dolby
Digital or DTS technology to recreate a dynamic sound that gives you the feeling of being in a public theater.
• Dolby Digital/DTS + DSP sound field effect
PresenceDSP These programs use YAMAHA's tri-field DSP processing
sound field 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.

Dolby Pro Logic + DSP sound field effect
Most 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.
• Dolby Pro Logic ]I
Dolby Pro Logic 11 decodes Dolby Surround software into 5 discrete full-range channels (3 channels in front and 2
channels in rear). There are 2 modes; MOVIE for movies and MUSIC for 2-channel audio sources.
