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
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-V2500 and RX-V1500)
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.
Audio Delay for Adjusting Lip-Sync
A Yamaha LSI provides synchronization of images
and sound, which is called lip-sync. The video
signal goes through the video processor circuit
before it is displayed, which takes time, so it lags
behind the audio. The LSI accurately aligns them
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 you in an
unmatched surround sound experience. You hear
movies and music with accurate sound

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.
