FEATURES ➤ What you can do with the unit En 8
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 HD
“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.
