How Sound Propagates

Expanding Frequency Response
Yamaha was able to fit all the High Definition
CINEMA DSP circuitry (that’s a lot of
processing power!) on a single board in its own
chamber, for greater efficiency and isolation
from possible interference.
Best Surround Realism
you in an unmatched surround
sound experience. You hear movies
and music with accurate sound
localization, smooth movement
across the sound space, exceptional
clarity and remarkably realistic
presence. It will seem as if the walls
of your room have disappeared and
you are in the middle of your own
immense theater!
Yamaha Uses Actual Sound
Field Data
Yamaha developed a technique called
Single Point Quad Miking to
precisely capture the acoustic patterns
of sound spaces. This complex data is
stored and processed on extremely
sophisticated LSIs designed and
manufactured by Yamaha.
4-Layer DSP Processing Board
All of the DSP IC chips and related
circuitry are located together on a 4-
layer board, which provides a number
of advantages. The dimensions are
smaller (2/3 previous types), so signal
paths are shorter and there is more
space for the large power supply
components. Digital interference is
reduced and impedance is lower as well.
Yamaha’s Exclusive YSS-930 32-Bit
Floating Point Quantization LSI
(RX-Z9, RX-V2400 and RX-V1400)
This powerful LSI performs all Dolby
Digital and DTS decoding with
extreme accuracy, as well as all digital
sound field processing, capabilities that
previously
required two or
more chips. It
also outperforms
other chips in
the precise
synchronization
of images and
sound.
Conventional multi-channel systems
base their sound on Dolby Digital and
DTS decoding, using relatively simple
matrix and steering techniques to
create surround sound effects.
Yamaha’s CINEMA DSP Digital
technology is much more sophisticated.
It naturally decodes the Dolby Digital
and DTS movie sound formats, but it
also draws on a huge memory of real-
world data from actual venues
(especially for the music programs) and
input from movie sound technicians.
This data is stored and processed on
Yamaha-developed LSIs, the most
powerful audio chips in the world.
Way Beyond Ordinary Surround
Sound
Our latest technology, Quad-Field
CINEMA DSP actually creates four
independent sound fields (front,
surround left, surround right and
surround back) that merge to envelop

High Definition CINEMA DSP Technology (RX-Z9)
The RX-Z9 has six times greater DSP capacity than previous models, thanks to an increase from 48kHz to 96kHz/24-bit A/D converters that can accept 96kHz
signals for direct digital conversion and processing. Higher density processing enables approximately triple the amount of early reflection data to be handled, for
significantly richer surround sound performance. The RX-Z9 also employs 192kHz/24-bit D/A conversion and DSP processing and Yamaha’s 32-Bit Floating-Point
Quantization System LSIs (four YSS-930s) for high precision decoding of Dolby Digital, DTS Digital Surround, DTS 96/24, DTS-ES Discrete 6.1, DTS-ES Matrix
6.1, DTS Neo:6 and Dolby Pro Logic IIx formats.
