Dolby Surround Setup - Sony Model STR-DE435 Operating Instructions Manual

Getting Started

Dolby Surround Setup

Dolby Pro Logic Surround is a system for decoding
Dolby Surround sound that is standardized for TV
programmes and movies. By selecting the proper
centre mode and adjusting the speaker volume, you
can reproduce highly precise localization and dynamic
panning of sounds of Dolby Surround encoded
software.
To obtain the best possible surround effect, you will
require at least one additional pair of speakers and/or
a centre speaker.
Locating the speakers
For optimum Dolby Pro Logic Surround sound, locate
your speakers as shown below.

Selecting the centre mode
The receiver offers you four centre modes:
PHANTOM, 3 STEREO, NORMAL, and WIDE. Each

Adjusting the speaker volume
The test tone feature lets you set the volume of your
rear speakers and/or centre speaker to the same level
as that of the front speakers to maximize the Dolby Pro
Logic Surround effect. (If all of your speakers are equal
in performance, you don't have to adjust the speaker
volume.)
Using the controls on the remote, you can adjust the
volume level from wherever you're listening.

the front speakers
The sound of the rear

the front speakers
The bass sound of the
