Yamaha YSP-4300 User Manual

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 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.
