Notes on Dolby Digital, DTS and MPEG Installation of Speaker System
DOLBY DIGITAL 5.1CH
Dolby Digital is the three-dimensional sound effect technology through digital signal processing of the next
generation, developed by Dolby Laboratories, and provides the sound completely split by six channels.
Six channels in Dolby Digital are called as 5.1-channel, of which 5 means the front L/R, center and rear L/R
channels. These five channels provide all audible frequency range of 20 – 20,000 Hz. Meanwhile, 0.1 channel
means the subwoofer, providing the bass range below 120 Hz.
Digital symbol is marked on the DVD.
DTS 5.1CH
DTS is the technology developed by Digital Theater Systems, Inc. Like Dolby Digital, it also provides the six-
channel mode consisting of front L/R, center, rear L/R and subwoofer and the same frequency range.
The difference between DTS and Dolby Digital lies in the data compression. Dolby Digital has a higher compression
ratio than DTS, thus occupying less space in the storage media. On the other hand, DTS occupies larger space
with a lower compression ratio but has gained a reputation that more emphasis is placed on the sound quality.
symbol is marked on the DVD.
MPEG 5.1CH
MPEG is a method of compression techniques for reproducing high quality of video and audio signals for
digital TV or DVD. Like Dolby Digital and DTS, it provides the six-channel mode consisting of front L/R,
center, rear L/R and subwoofer and the same frequency range.
MPEG )l( Multichannel symbol is marked on the DVD.
DOLBY DIGITAL 2CH/DTS 2CH/MPEG 2CH
It is the function of integrating six channels into two channels for output so that the digital strips encoded in
six channels can be made compatible with the conventional 2-channel stereo system.
As this unit basically supports six channels, it may not be necessary to convert the input signals for 2-channel
system, but if the DVD to be played is encoded in 2 channels, it is played in 2CH mode.
To achieve the optimum quality of the sound effect provided by this unit, it is very
important to position the speakers properly. Refer to the following description for a better
sound experience.
• Front L/R Speakers: Install the speakers on the left and right side in front of the listener at the
height of the listener’s ears and arrange the speakers to aim at the listening
position.
• Center Speaker: Install the speaker at the front center at the height of the listener’s ears.
• Surround L/R Speakers: Install the speakers on the left and right side in the rear of the listener at
the height of the listener’s ears and arrange the speakers to aim at the
listening position.
• If the speakers cannot be positioned at the height of the listener’s ears because of the structure of
the room, install the speaker above the listener’s ears. Make sure that the speakers are placed to
aim at the listening position.
• Subwoofer: Install the speaker on the floor in front of the listener.
*
Install the subwoofer on hard floor keeping a distance of at least 10cm to the wall.
*
Since there is a speaker on the left of the main unit, make sure that the left side is clear of any
obstruction.
When installing the subwoofer, keep a
distance of at least 10cm to the wall
and at least 30cm to the TV.
