Sound and Volume Controls

Selecting the surround sound
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 Surround, DTS, Dolby Pro
Logic or ProLogic 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
surround modes are shown below.
Dolby Digital Surround
Dolby Digital (also known as AC-3 or Dolby 5.1) and MPEG
Multichannel delivered a realistic and dynamic sound similar
to theater 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, 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 are
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 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 properties of the original recording without adding
any new sounds or tonal colorations.

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 Prologic MPEG or Dolby Digital surround channel is
processed by a 'virtualizer' 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
pre-set modes that control the frequency bands of sound
to optimize certain musical styles. It greatly enhances the
excitement and enjoyment of your favorite music.
Press SOUND repeatedly to select the available sound
effect.
