Yamaha DSP-A2 Owner's Manual

6
Dolby Pro Logic + 2 Digital Sound Fields
Digital sound fields are created on the presence side and
the rear surround side of the Dolby Pro Logic Surround-
decoded sound field respectively. They create a wide
acoustic environment and emphasize surround-effect in the
room, letting you feel much presence as if you were
watching a movie in a popular Dolby Stereo theater.
This combination is available when the digital sound field
program No. 8, 9, 10, 11 or “PRO LOGIC/Enhanced” of No.
12 is selected, and the input signal of the source is analog,
PCM audio or encoded with the Dolby Digital in 2-channels.
Dolby Digital or DTS + 3 Digital Sound Fields
Digital sound fields are created on the presence side and
the independent left and right surround sides of the Dolby
Digital-decoded or the DTS-decoded sound field
respectively. They create a wide acoustic environment and
much surround effect in the room without losing high
channel separation. With wide dynamic range of Dolby
Digital or DTS sound, this sound field combination lets you
feel as if you were watching a movie in the newest Dolby
Stereo Digital theater or DTS installed theater. This is the
most ideal home theater sound at the present time.
This combination is available when the digital sound field
program No. 8, 9, 10, 11 or “DOLBY DIGITAL (or DTS
DIGITAL SUR.)/Enhanced” of No. 12 is selected, and the
input signal of the source is encoded with the Dolby Digital
(except in 2-channels) or encoded with the DTS.
CINEMA DSP: Dolby Surround + DSP / DTS + DSP
The Dolby Surround sound and DTS systems show their full
ability in a large movie theater, because movie sounds are
originally designed to be reproduced in a large movie theater
that uses a multitude of speakers. Trying to create a sound
environment similar to that of a movie theater in your home is
difficult because of the room size, material inside the walls, the
number of speakers, and so on. In other words, your listening
room is very different from a movie theater.
However, Yamaha DSP technology allows you to create nearly
the same sound experience as that of a large movie theater in
your home by compensating for the lack of presence and
dynamics in the listening room with original digital sound fields
combined with Dolby Surround or DTS Digital Surround
sounds.
The YAMAHA “CINEMA DSP” logo indicates those programs
that are created by the combination of YAMAHA DSP
technology and Dolby Surround or DTS.
