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
®
XT to
provide well-balanced sound for every listener at any volume level.
Audyssey Dynamic Surround Expansion (A-DSX)
Audyssey DSX
®
is a scalable system that adds new speakers to improve
surround sound vividness.
Starting with a 5.1 system Audyssey DSX
®
first adds Wide channels for
the biggest impact on envelopment. Research in human hearing has
proven that information from the Wide channels is much more critical in
the presentation of a realistic soundstage than the Back Surround
channels found in traditional 7.1 systems.
Audyssey DSX
®
then creates a pair of Height channels to reproduce the
next most important acoustical and perceptual cues. In addition to these
new Wide and Height channels, Audyssey DSX
®
applies Surround
Envelopment Processing to enhance the blend between the front and
surround channels.
Audyssey Dynamic Volume
®
Dynamic Volume solves the problem of large variations in volume level
between television programs, commercials, and between the soft and loud
passages of movies. Audyssey Dynamic EQ
®
is integrated into Dynamic
Volume so that as the playback volume is adjusted automatically, the
perceived bass response, tonal balance, surround impression, and dialog
clarity remain the same.
Audyssey MultEQ
®
XT
Audyssey MultEQ
®
XT is a room equalization solution that calibrates any
audio system so that it can achieve optimum performance for every
listener in a large listening area. Based on several room measurements,
MultEQ
®
XT calculates an equalization solution that corrects for both time
and frequency response problems in the listening area and also performs
a fully automated surround system setup.
