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 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® XT32
MultEQ® XT32 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®
XT32 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.
