The excitement of a concert hall and the powerful sense of being inside a movie - we all want to enjoy these 
experiences in our own living room. Yamaha has pursued the fulfillment of these desires for more than 20 years, and 
this fulfillment has now taken shape as the Yamaha AV receivers.
What is a sound field?
We perceive sound from a voice or an instrument not 
only as the sounds that are heard directly but also as 
the “reflected” or “reverberant” sound that has been 
reflected by the walls or ceiling of the building. The 
character of the reflected and reverberant sound is 
affected by the shape, size, and material of the building, 
and all of these sounds taken together are what give us 
the auditory sensation of being in that specific place.
This unique acoustical character of a specific space is 
what we call the “sound field”.

CINEMA DSP/CINEMA DSP 3D
Yamaha has accumulated a massive amount of 
acoustical data by analyzing the actual sound fields of 
concert halls and performance spaces around the 
world. “CINEMA DSP” allows this data to be applied to 
create sound fields. This unit contains a wide variety of 
sound programs using CINEMA DSP.
By selecting a sound program that is appropriate to the 
content of the playback source such as movies, music, 
or games, you can maximize the acoustical 
effectiveness of that specific content. (For example, a 
sound program designed for movies can give you the 
sensation of actually being in that scene.)
In addition, the “CINEMA DSP 3D” function uses 
3-dimensional sound field data that includes the axis of 
height, generating an even more realistic sound field 
with a spatial sense.
CINEMA DSP HD3 
“CINEMA DSP HD³” is Yamaha's flagship 3D sound field 
playback technology that takes full advantage of the 
massive amount of acoustic reflection data included in the 
sound field data. With support for rear presence speaker 
output, it delivers more than twice as much capability for 
generating acoustic reflections as conventional CINEMA 
DSP 3D, in addition to high-frequency playback capability, 
delivering an utterly natural and powerful spatial sound field.

The included YPAO microphone can be used to analyze 
the environment so that this information can be used to 
automatically adjust various settings for the speakers and 
the sound field. This allows the distinctive character of the 
content you are hearing to be maximized, and optimizes 
the effectiveness of Yamaha's sound field generating 
technology for your specific listening environment.
YPAO-R.S.C.
In rooms that have not been designed or constructed 
with acoustics in mind, reflections from the walls or 
ceiling can cause problems such as a blurred 
low-frequency range or a smearing of the acoustical 
image. “YPAO-R.S.C.” is technology that reduces only 
the unwanted reflections that can be difficult to avoid in 
a typical home. This corrects the tonal changes and 
inconsistencies in the sound field that can occur due to 
speaker placement, thus creating a listening 
environment comparable to that of a room specifically 
designed for acoustic perfection.
Angle measurement 
The direction (angle) of the front 
speakers, surround speakers, 
and presence speakers as seen 
from the listening position is 
measured, and compensation 
is applied to the sound field in 
order to maximize the 
effectiveness of the CINEMA DSP sound field.
