■ 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.

■ 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
* In contrast to a full 1-channel band, a component
designed to enhance low frequency sound for added
effect.
■ Deep Color
Deep Color refers to the use of various color depths in
displays, up from the 24-bit depths in previous
versions of the HDMI specification. This extra bit
depth allows HDTVs and other displays go from
millions of colors to billions of colors and eliminate
on-screen color banding for smooth tonal transitions
and subtle gradations between colors. The increased
contrast ratio can represent many times more shades of
gray between black and white. Also Deep Color
increases the number of available colors within the
boundaries defined by the RGB or YCbCr color space.
■ 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.
