A channel is an audio type that has been divided based on the
range and other characteristics.
Ex. 7.1 channel
• For front speakers, Left (1ch), Right (1ch)
• For center speaker (1ch)
• For surround speakers, Left (1ch), Right (1ch)
• For surround back speakers, Left (1ch), Right (1ch)
• For the 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.
Deep Color is a type of video signal that can be transmitted by the
HDMI jacks of this unit. 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.
This front surround speaker system is a revolutionary system
capable of true surround sound. The Digital Sound Projector
synthesizes up to five channels of sound beams and outputs front,
center, and surround channel signals from the center unit. By
reflecting front and rear beams off of walls, this system enables
true surround sound. 7-channel playback can also be achieved by
combining front and surround signals.
This unit uses the subwoofer for an additional 0.1 channel. A
typical speaker system requires seven speakers (two front
speakers, a center speaker, two surround speakers, two surround
back speakers, and a subwoofer) in addition to an amplifier to
achieve 7.1-channel playback.
This unit creates surround sound by reflecting projected sound
beams off the walls of your listening room.
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 is an advanced audio technology developed
for high-definition programming and media including HD
broadcasts, and Blu-ray Disc. Selected as an 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 recorders 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 IIx is a new technology enabling discrete
multichannel playback from 2-channel or multi-channel sources.
There are three modes available: “Music mode” for music
sources, “Movie mode” for movie sources (for 2-channel sources
only) and “Game mode” for game sources.
Dolby TrueHD is an advanced lossless audio technology
developed for high-definition disc-based media including Blu-ray
Disc. Selected as an audio standard for Blu-ray Disc, this
technology delivers sound that is bit-for-bit identical to the studio
master, offering a high-definition home theater experience.
Supporting bitrates up to 18.0 Mbps, Dolby TrueHD can carry up
to 8 discr
e
te channels of 24-bit/96 kHz audio simultaneously.
Dolby TrueHD also remains fully compatible with the existing
multichannel audio systems and retains the metadata capability of
Dolby Digital, allowing dialog normalization and dynamic range
control.
