Explanation of terms
o Audyssey
Audyssey Dynamic EQ ®
Dynamic EQ solves the problem of deteriorating sound quality as volume
is decreased by taking into account human perception and room
acoustics.
Audyssey Dynamic EQ
® works in tandem with Audyssey MultEQ ® XT32
to provide well-balanced sound for every listener at any volume level.
Audyssey Dynamic Surround Expansion (A-DSX)
Audyssey DSX
® is a new surround enhancement technology that raises
the surround effect and impression to realize a larger surround space by
adding a new channel to the existing 5.1 channel system.
In research on human hearing characteristics, two points can be broadly
cited as elements that enhance the surround effect. The most important
point is the creation of horizontal spread (wide channel) at the front
(forward) area in composing a realistic surround space. The next
important point is the creation of vertical spread (height channel) in the
front (forward) area using recognizable (audible) acoustic signals so as to
create a surround space with depth.
Audyssey DSX
® then creates a pair of Height channels to reproduce the
next most important acoustical and perceptual cues. In addition, Audyssey
DSX
® does not simply add a channel but combines the existing front,
surround and rear surround sound to develop a technology known as
“Surround Envelopment Processing” which has been incorporated into
Audyssey DSX
® to further enhance the effect.
