DESCRIPTION OF TERMINOLOGY
Dolby Pro Logic Surround:
This refers to the Dolby Surround sound decoder system
which is used for movies. Using 4 channels, the sound ef-
fects, dialogue, sound direction, music, etc. are all repro-
duced more realistically. Dolby Pro Logic Surround makes
the location and movement of sounds much more natural
than the original Dolby Surround system. You can enjoy a
realistic, powerful feeling like being at a live performance or
as if you were at a movie theatre or in a concert hall. In
order to enjoy this effect, you need at least one pair of sur-
round speakers.
Dolby Digital:
This is the new digital surround system that was created to
reproduce theatre quality stereophonic Dolby Surround
sound at home. Films are now recorded using the 5.1 chan-
nel system. Dolby Digital can handle the original sound track
without modification, allowing you to enjoy the sound field
created by the film maker at home.

Dolby Surround:
This is the encoding/decoding system for general-purpose
Dolby Surround. When the sound from films recorded in
Dolby Surround are reproduced, you will have the feeling of
being at a live performance, as if the action is taking place
right in front of you.
LFE (Low Frequency Effect):
This refers to the special low-frequency sound effects used
in Dolby Digital recordings.
When a signal containing LFE encoding is played by this
unit, "LFE" will appear in the display.
PCM (Pulse Code Modulation)
This is a recording/transmission system used for digital audio
signals. This unit can handle sampling frequencies of 32 kHz,
44.1 kHz and 48 kHz.
Sub woofer:
The sub woofer is a special speaker used to emphasise bass
sounds.
In Dolby Digital, this speaker reproduces the LFE signals as
well as the low-frequency signals being sent to the front,
centre and surround speakers.
In Dolby Pro Logic, this speaker reproduces the low-fre-
quency signals sent to the front and centre speakers.
It also reproduces low frequency sounds from ordinary stereo
recordings.
