AIR SURROUND XTREME
This system 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, and a subwoofer are necessary for enjoying 5.1 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.
Channel (ch)
A channel is an audio type that has been divided based on range
and other characteristics.
Ex. 7.1 channel
• Front speakers, Left (1ch), Right (1ch)
• Center speaker (1ch)
• Surround speakers, Left (1ch), Right (1ch)
• Surround back speakers, Left (1ch), Right (1ch)
• Subwoofer (1ch × 0.1* = 0.1ch)
* In contrast to a full 1-channel band, a component designed to
enhance low frequency sound for added effect.
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. 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.
