Yamaha HTR-5835 Dolby Pro Logic, Dolby Surround, DTS Digital Theater Systems Digital Surround

•Dolby Digital

Dolby Digital is a digital sun'ound sound system that gives

you completely independent multi-channel audio. With 3 front channels (left, center, and right), and 2 sun'ound stereo channels, Dolby Digital provides 5 full-range audio

channels. With an additional channel especially for bass

effects, called LFE (low frequency effect), the system has

a total of 5.1-channels (LFE is counted as 0.1 channel). By

using 2-channelstereo for the sun'ound speakers, more

accurate moving sound effects and surround sound

environment are possible than with Dolby Surround. The

wide dynamic range (from maximum to mininmm

volume) reproduced by the 5 full-range channels and the

precise sound orientation generated using digital sound

processing provide listeners with previously unheard of

excitement and realism.

With this unit, any sound environment from monaural up

to a 5.1-channel configuration can be fi'eely selected for your el_ioyment.

•Dolby Pro Logic II

Dolby Pro Logic II is an improved technique used to decode vast numbers of existing Dolby Sun'ound

software. This new technology enables a discrete 5- channel playback with 2 front left and right channels, 1 center channel, and 2 sun'ound left and right channels

(instead of only 1 sun'ound channel for conventional Pro

Logic technology). Music and Game modes are also available for 2-channelsources in addition to the Movie mode.

•Dolby Surround

Dolby Surround uses a 4 channel analog recording system

to reproduce realistic and dynamic sound effects: 2 front left and right channels (stereo), a center channel for dialog

(monanral), and a surround channel for special sound

effects (monaural). The sun'ound channel reproduces sound within a narrow fi'equency range.

Dolby Sun'ound is widely used with nearly all video tapes

and laser discs, and in many TV and cable broadcasts as well. The Dolby Pro Logic decoder built into this unit

employs a digital signal processing system that

automatically stabilizes the volume on each channel to enhance moving sound effects and directionality.

•DTS 96/24

DTS 9624 offers an unprecedented level of audio quality

for multi-channel sound on DVD-Video, and is fully

backward-compatible with all DTS decoders. "96" refers

to a 96 kHz sampling rate (compared to the typical 48 kHz sampling rate). "24" refers to 24-bitword length. DTS 96/

24 offers sound quality transparent to the original 96/24

master, and 96/24 5.1-channel sound with full-quality full- motion video for nmsic programs and motion picture

soundtracks on DVD-video.

•DTS (Digital Theater Systems) Digital Surround

DTS digital sun'ound was developed to replace the analog

soundtracks of movies with a 6-channel digital sound

track, and is now rapidly gaining popularity in movie theaters around the world. Digital Theater Systems Inc.

has developed a home theater system so that you can enjoy the depth of sound and natural spatial representation of DTS digital surround in your home. This system

produces practically distortion-free 6-channel sound

(technically, a left, right and center channels, 2 sun'ound

channels, plus an LFE 0.1 channel as a subwoofer, for a

total of 5. i-channels). The unit incorporates a DTS-ES

decoder that enables 6.1- channel reproduction by adding the sun'ound back channel to existing 5.1 -channel format.

•Neo:6

Neo:6 decodes the conventional 2-chmmelsources for 6

channel playback by the specific decoder. It enables

playback with the full-range channels with higher

separation just like digital discrete signal playback. Two

modes are available; "Music mode" for playing music sources and "Cinema mode" for movies.
