This unit is equipped with a variety of precise digital decoders that allow you to enjoy multi-channel playback from
stereo or multi-channel sources. This unit is also equipped with a Yamaha CINEMA DSP (digital sound field processing)
chip containing several sound field programs used to enhance your playback experience. Most of the CINEMA DSP
programs are precise digital recreations of actual acoustic environments found in famous concert halls, music venues, and
movie theaters.
y
The Yamaha CINEMA DSP programs are compatible with all Dolby Digital, DTS, and Dolby Surround sources.
Note
Choose a CINEMA DSP program based on your listening preference and do not purely rely on the name of the CINEMA DSP program
itself.
What is a sound field?
A significant factor that creates the rich, full tones of a live instrument is the multiple reflections from the walls of the
room. In addition to making the sound live, these reflections enable the listener to tell where the player is situated as well
as the size and shape of the room in which the listener is sitting.
Elements of a sound field
In any environment, there are two distinct types of sound reflections combined with the direct sound coming straight to
our ears from the player's instrument to make up the sound field.
Early reflections
Reflected sounds reach our ears extremely rapidly (50 ms to 80 ms after the direct sound) after reflecting from one
surface only (from the ceiling or the wall, for example). Early reflections help add clarity to the direct sound.
Reverberations
These are caused by reflections from more than one surface (i.e., wall, ceiling, the back of the room, etc.) so numerous
that they merge together to form a continuous sonic afterglow. They are non-directional and lessen the clarity of the direct
sound.
Direct sound, early reflections, and subsequent reverberations all together help us determine the subjective size and shape
of the room, and it is this information that the digital sound field processor reproduces in order to create the sound fields.
With the appropriate early reflections and subsequent reverberations in your listening room, you can create your own
listening environment. The acoustics in your room could be changed to those of a concert hall, a dance floor, or a
listening room of virtually any size at all. This ability to create sound fields at will is exactly what Yamaha has done with
the CINEMA DSP technology.
