Selecting the surround sound
mode
IMPORTANT!
– For proper surround sound, make sure you have
followed the “Connections” and “Preparations”
procedures fully.
– The centre and surround speakers only operate
when the system is set to surround sound mode
and the source material being played is recorded
or broadcast in Dolby Digital, DTS or Dolby Pro
Logic surround sound.
– Stereo broadcasts or recordings will produce
some surround channel effects when played in a
surround mode. However, mono sources will not
produce any sound from the surround speakers.
● Press SURROUND to select surround or stereo mode.
➜ The availability of the various surround sound modes
depend on the number of speakers used and the incoming
sound information available on the disc. The available output
modes are shown below.
Dolby Digital Surround
Dolby Digital (also known as AC-3 or Dolby 5.1) and
MPEG Multichannel delivers a realistic and dynamic sound
similar to theatre and cinema. It requires connection of all
five speakers (front left/right, centre, surround left/right) and
subwoofer for correct Dolby Digital Surround sound
reproduction. Each channel plays its own unique role in
providing the right sound. Front left, centre and right join
two surround speakers to reproduce high, mid and bass
frequencies in five full-range channels of surround. Bass
rumble, explosions and low frequency effects you feel are
delivered through the subwoofer. A large number of DVD
discs have been recorded in Dolby Digital Surround.
DTS Surround
The DTS Surround is a cinema surround sound format that
offers superior digital audio performance. DTS offers more
clarity and definition especially for higher tones. The better
sound quality is a result of the limited sound compression
(3:1 instead of 11:1 for Dolby Digital) and the 20-bit
resolution.
Dolby Pro Logic Surround
The Dolby Pro Logic Surround system is a specially
encoded two-channel analogue format that will produce
sound through four speaker channels (front left, centre,
front right, mono surround) when a Dolby Pro Logic
Decoder is used. It is also compatible with stereo systems
but the user will only have two-channel (front left & right)
of sound.
Matrix
A new surround playback system that delivers amazingly
rich and convincing five-channel surround outputs (front
left/right, centre, surround left/right).
VSS (Virtual Surround Sound)
The ProLogic MPEG or Dolby Digital surround channel is
processed by a ‘virtualiser’ DSP to add surround effect from
just the two front speakers.
Stereo
All sound is reproduced and played through the front left
and right speakers. This enables standard stereo
reproduction.
Selecting the digital sound
effect
The digital sound effects allow you to select from various
pre-set modes that control the frequency bands of sound
to optimise certain musical styles. It greatly enhances the
excitement and enjoyment of your favourite music.
● Press SOUND repeatedly to select the available sound
effect.
