AIR SURROUND XTREME
This unit employs new technologies and algorithms that
make it possible to achieve 7-channel surround sound with
only front speakers, and without using wall reflections.
Ordinarily, two front speakers, a center speaker, two
surround speakers, two surround back speakers, and a
subwoofer are necessary for enjoying 7.1 channel
surround sound.
Virtual 7.1 channel
The AIR SURROUND XTREME technology, using only
front speakers and subwoofer, enables you to enjoy a
realistic 7.1 channel sound by simulating sound from
virtual speakers at center, surround, and surround backs.
■
Sampling frequency
The number of sampling (process for digitalizing analog
signals) per second. In principle, the higher the sampling
rate, the wider the frequency range that can be played
back, and the higher the quantized bit rate, the finer the
sound that can be reproduced.
■
Dolby Digital
Digital surround sound system which is developed by
Dolby Laboratories provides completely independent
multi-channel audio. With 3 front channels (left, center,
and right) and 2 surround stereo channels, Dolby Digital
provides five full-range audio channels. With an
additional channel especially for bass effects (called LFE,
or low frequency effect), the system has a total of 5.1
channels (LFE is counted as 0.1 channel). By using 2
channel stereo for the surround speakers, more accurate
moving sound effects and surround sound environment
are possible than with Dolby Surround.
■
Dolby Digital Plus
Dolby Digital Plus is an advanced audio technology
developed for high-definition programming and media
including HD broadcasts, and Blu-ray Disc. Selected as an
optional audio standard for Blu-ray Disc, this technology
delivers multichannel sound with discrete channel output.
Supporting bitrates up to 6.0 Mbps, Dolby Digital Plus
can carry up to 7.1 discreet audio channels
simultaneously. Supported by HDMI and designed for the
optical disc players and AV receivers/amplifiers of the
future, Dolby Digital Plus also remains fully compatible
with the existing multichannel audio systems that
incorporate Dolby Digital.
■
Dolby Pro Logic II
It is an improved matrix decoding technology that
provides better spatiality and directionality on Dolby
Surround programmed material; provides a convincing
three-dimensional sound field on conventional stereo
music recordings; and is ideally suited to bring the
surround experience to automotive sound. While
conventional surround programming is fully compatible
with Dolby Pro Logic II decoders, soundtracks will be
able to be encoded specifically to take full advantage of
Pro Logic II playback, including separate left and right
surround channels.
