Using the Digital Surround System
Understanding the Digital Surround System |
The sound heard in a place such as a concert hall or a
movie theater consists of direct sound, an 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 differentiate these three
kinds of sound.
Types of the sound
Reverberation
LPOG
_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.
The TA-E1000ESD reproduces the early reflections and the
reverberation using its digital signal processor and allows
you to design a variety of soundfields in your own room.
The unit incorporates 10 types of surround modes, and
within each mode, you can adjust several parameters to
maximize the effect in your listening room.
