■ Dolby Digital
Dolby Digital is a digital surround sound system that gives 
you completely independent multi-channel audio. With 3 
front channels (front L/R and center), and 2 surround 
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-channel stereo for the surround 
speakers, more accurate moving sound effects and 
surround sound environment are possible than with Dolby 
Surround. The wide dynamic range from maximum to 
minimum volume reproduced by the 5 full-range channels 
and the precise sound orientation generated using digital 
sound processing provide listeners with unprecedented 
excitement and realism. With this unit, any sound 
environment from monaural up to a 5.1-channel 
configuration can be freely selected for your enjoyment.
■ Dolby Digital EX
Dolby Digital EX creates 6 full-bandwidth output 
channels from 5.1-channel sources. This is done using a 
matrix decoder that derives 3 surround channels from the 
2 in the original recording. For the best results, Dolby 
Digital EX should be used with movie sound tracks 
recorded with Dolby Digital Surround EX. With this 
additional channel, you can experience more dynamic and 
realistic moving sound especially with scenes with “fly-
over” and “fly-around” effects.
■ Dolby Pro Logic II
Dolby Pro Logic II is an improved technique used to 
decode vast numbers of existing Dolby Surround sources. 
This new technology enables a discrete 5-channel 
playback with 2 front left and right channels, 1 center 
channel, and 2 surround left and right channels instead of 
only 1 surround channel for conventional Pro Logic 
technology. There are three modes available: “Music 
mode” for music sources, “Movie mode” for movie 
sources and “Game mode” for game sources.
■ Dolby Pro Logic IIx
Dolby Pro Logic IIx is a new technology enabling discrete 
multi-channel 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 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 
(monaural), and a surround channel for special sound 
effects (monaural). The surround channel reproduces 
sound within a narrow frequency range. Dolby Surround 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 96/24 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-bit word 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 music programs and motion picture 
soundtracks on DVD video.
■ DTS (Digital Theater Systems)
Digital Surround
DTS digital surround was developed to replace the analog 
soundtracks of movies with a 6.1-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 6.1-channel sound (technically, 
front left and right, center, surround left and right and LFE 
0.1 (subwoofer) channels for a total of 5.1 channels). This 
unit incorporates a DTS-ES decoder that enables 6.1-
channel reproduction by adding the surround back channel 
to the existing 5.1-channel format.
■ ITU-R
ITU-R is the radio communication sector of the ITU 
(International Telecommunication Union). ITU-R 
recommends a standard speaker placement which is used 
in many critical listening rooms, especially for mastering 
purposes.
