Sony STR-D1011 - Manual (Page 32)

Adjusting the SOUND FIELD program
Understanding the Digital Surround Processor Characteristics of the SOUND FIELD program
The sound heard in a place such as a concert hall or a
movie theater consists of direct sound, and early reflected
sound (early reflections) and a reverberative sound
(reverberation). The acoustics of the room affect the way
these three sounds are heard. We can estimate the size or
the type of a hall by listening to and differentiating these
three kinds of sound.
The STR-D1011 reproduces the early reflections and the
reverberation using its digital signal processor and allows
you to design a variety of sound field in your own room.
The unit incorporates 10 types of the SOUND FIELD
program, and you can select the desired SOUND FIELD
mode by pressing the SOUND FIELD button. Also you can
adjust several parameters within each mode to maximize
the effect in your listening room.
The sound transition of the direct sound, early reflections
and reberveration can be illustrated as below:
Note
Each surround mode has several internal (fixed) parameters
in addition to the adjustable parameters explained in this
section. Therefore, surround modes will not become the
same even if you set all adjustable parameters the same.
