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 HD

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” 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.
