Channel (ch)

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

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.

The sound image of the system

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.

Digital Sound Projector

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.

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 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

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

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 discrete 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.
