PROFILE OF THIS UNIT
You are the proud owner of a Yamaha stereo receiver –an extremely sophisticated audio component. The Digital Sound Field
Processor (DSP) built into this unit takes advantage of Yamaha’s undisputed leadership in the field of digital audio processing to
bring you a whole new world of listening experiences. Follow the instructions in this manual carefully when setting up your system,
and this unit will sonically transform your room into a wide range of listening environments –movie theater, concert hall, and so on.
In addition, you get incredible realism from sources encoded with Dolby Surround using the built-in Dolby Pro Logic Surround
Decoder.
Please read this operation manual carefully and store it in a safe place for later reference.
Digital Sound Field Processing
Technological advances in sound reproduction over the last 30
years have enhanced the listening experience with improved
clarity, precision and power. However, something has still been
missing: The atmosphere and acoustic ambiance of the public
venue. Our Yamaha engineers have extensively researched
the nature of sound acoustics and the way sound reflects
inside a room. We sent these engineers to famous theaters
and concert halls around the world to measure the acoustics of
those venues with sophisticated microphones. The data they
collected is used to recreate these environments in digital
sound fields. Some of these digital sound fields are created
using data measured directly at the original venue; others are
created from combinations of data to form unique
environments for specific purposes.
You can use these sound fields to enhance any source and in
combination with the Dolby Pro Logic Surround technology.
Some are designed especially for music, and some especially
for movies.
Dolby Pro Logic Surround
Dolby Pro Logic Surround has been used in movie theaters
since the mid-seventies. It has also been available in home
entertainment systems since the late eighties and continues to
be a popular format for home theater systems. It uses four
discrete channels and five speakers to reproduce realistic and
dynamic sound effects: two main channels (left and right), a
center channel for dialog, and a rear channel for special sound
effects. The rear channel reproduces sound within a narrow
frequency range.
Most video tapes and laser discs include Dolby Pro Logic
Surround encoding as do many TV and cable broadcasts. The
Dolby Pro Logic Surround decoder built into this unit employs a
digital signal processing system that stabilizes each channel
for even more accurate sound positioning than is available with
standard analog processors.

Dolby Pro Logic Su DSP
The Dolby Surround sound system shows its full ability in a
large movie theater, because movie sounds are originally
designed to be reproduced in a large movie theater that uses a
multitude of speakers. Trying to create a sound environment
similar to that of a movie theater in your home is difficult
because of the room size, material inside the walls, number of
speakers, and so on. In other words, your listening room is
very different from a movie theater.
However, Yamaha DSP technology allows you to create nearly
the same sound experience as that of a large movie theater in
your home by compensating for the lack of presence and
dynamics in the listening room with its original digital sound
fields combined with Dolby Surround sound field.
The combination of Dolby Pro Logic Surround and DSP is used
on the sound field program “
PRO LOGIC ENHANCED”.
The YAMAHA “CINEMA DSP” logo indicates these programs that
are created by the combination of Dolby Pro Logic and YAMAHA
DSP technology.
