Selecting the surround mode
IMPORTANT!
–For proper surround sound, make sure you have
followed the “Connections” and “Preparations”
procedures fully.
–The center 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, Dolby Pro Logic or
Pro Logic II surround sound.
–Stereo broadcasts or recordings will produce some
surround channel effects when played in a surround
mode. However, monaural sources will not produce
any sound from the surround speaker.
●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.
Notes
Surround sound is not available in DISC 6CH mode.
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
theater and cinema.  It requires connection of all five
speakers (front left/right, center, 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, center and front 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 recorded in Dolby Digital Surround.)
DTS Surround
The DTS Surround is a cinema surround sound format that
offer s 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 channels analog format that will produce sound through
four speaker channels (front left, center, front right, monaural
surround) when a Dolby Pro Logic Decoder is used. It is also
compatible with stereo systems but the user will only have
two channels (Front left & Right) of sound.
Dolby Pro Logic II Surround
Dolby Pro Logic II Surround creates five full bandwidth
output channels from two-channel sources. This is done using
an advanced, high purity matrix surround decoder that
extracts the spatial proper ties of the original recording
without adding any new sounds or tonal colorations.
Movie mode
The movie mode is for use with stereo television shows and
all programs encoded in Dolby Surround. The result is
enhanced soundfield directionality that approaches the
quality of discrete 5.1-channel sound.
Music mode
The Music mode is for use with any stereo music recordings,
and provides a wide and deep sound space.
VSS (Virtual Surround Sound)
The Pro Logic MPEG or Dolby Digital surround channel is
processed by a ‘vir tualizer’ 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 allows you to select from various
preset modes that control the frequency bands of sound to
optimize cer tain musical styles. It greatly enhances the
excitement and enjoyment of your favorite music.
●Press SOUND repeatedly to select the available
sound effect.
In Dolby Digital, DTS, Dolby Pro Logic, Pro Logic II
(movie) mode, select :
–CONCERT, DRAMA, ACTION or SCI-FI
In Stereo, VSS, Pro Logic II (music) mode, select :
–JAZZ, ROCK, DIGITAL or CLASSIC
