Contents Connections Playback 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. Settings Tips Appendix 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.
