Glossary
Analogue
Audio signals produced from L/R audio output terminals of
general equipment is called analogue audio.
CPPM (Content Protection for Prerecorded
Media)
This is the copyright protection technology which prevents fi le
copy of DVD audio.
Decoder, Decode
Decoder is the device to enable us to hear audio data that is
encoded on DVD, etc., as a normal audio signal. This process
is called Decode.
Digital
Blu-ray Disc players, DVD recorders, DVD players, and CD
players are usually equipped with digital output terminals.
Connect through the digital terminal to enjoy digital surround
systems such as Dolby Digital and DTS.
Dolby Digital (DVD etc.)
Digital surround system developed by Dolby Laboratories.
Dolby Pro Logic
This system can process not only Dolby Surround, but also
other 2-channel sources to produce a 5.1-channel sound for
a more realistic sound fi eld. It is also possible to enhance old
movies recorded in stereo with this dynamic 5.1-channel sound.
This system uses Dolby Pro Logic
stereo sources such as video cassettes and CDs.
D olby Virtual Speaker
This system allows you to enjoy a surround effect with two front
speakers, a center speaker, and a subwoofer. This is not merely
a "virtual surround" effect, but rather uses the optimal speaker
arrangements and listening positions for 5.1-channel sound.
DTS (Digital Theater Systems)
Digital surround system developed by DTS, Inc.
Dynamic range
Dynamic range is the difference between the lowest level of
sound that can be heard above the noise of the equipment and
the highest level of sound before distortion occurs.
HDMI (High Defi nition Multimedia Interface)
HDMI enables you to transmit digital audio and video signals
using a single cable.
You can also transmit control signals using HDMI connections.
LPCM (Linear PCM)
This is one of the PCM methods and the uncompressed audio
signal encoded digitally. This method is used for music CD, etc.
Multi-channel LPCM signals used for Blu-ray Disc, DVD audio,
etc. enable playback with higher-sound quality.
Up to 7.1 channel LPCM signals can be entered to this system.
Maintenance
Unplug the AC mains lead from the household mains socket and wipe the system using a soft and dry cloth.
•
When the system is very dirty, wring the cloth soaked in water thoroughly, wipe the dirt and wipe moisture off with a
dry cloth.
•
Do not use solvents such as benzine, thinner, alcohol, etc. because they may cause casing to deform and coating to
go off.
•
Before using chemically treated cloth, read the instructions that come with the cloth carefully.

Optical
Using optical fi bre cable for digital signal input/output from DVD,
CD, etc., provides better sound quality for playback or recording
compared to analogue. Only possible with equipment that has
an optical terminal.
PCM (Pulse Code Modulation)
This is one of the methods that enables analogue sounds to be
converted to digital sounds.
Sampling frequency
Sampling is the process of converting the heights of sound
wave (analogue signal) samples taken at set periods into digits
(digital encoding).
Sampling frequency is the number of samples taken per
second, so larger numbers mean faithful reproduction of the
original sound.
Standby through function
When this system and TV and DVD recorder are connected
with HDMI cables, image/audio from DVD recorder can still be
transmitted to TV even though the system is turned off.
This is useful when you want to enjoy late night viewing only
with the television's speakers.
Images recorded with x.v.Colour are also supported.
Surround signal
Audio signal made up with front speakers, center speaker
and surround speakers. For this system, surround signal is
automatically played by Dolby Virtual Speaker.
x.v.Colour
This is a name of products compliant with ISO Standard for
wider colour space: "xvYCC". This system supports x.v.Colour.
1080p
This is one of the digital hi-vision images.
1080 is the number of effective scanning lines that constitute
the actual screen. This enables every detail to be beautifully
expressed. Images are less fl ickered with progressive method
that scans in order from the top. This system supports 1080p.
5.1 channel surround
Monaural and stereo use one channel and two channels
respectively to reproduce sound, but 5.1-channel surround
uses 5 speakers and a low frequency effect channel. The
5 channels are: 1 center speaker, 2 front speakers, and 2
surround speakers at the side of or to the rear of the sitting
position. Sound output of the subwoofer is much narrower than
the other speakers, and so is considered as 0.1. This is called
5.1-channel surround when played through all 5.1 channels,
and with this system you can achieve a similar effect with Dolby
Virtual Speaker.
