Dolby Digital (AC-3)
The Dolby Digital (AC-3) surround format lets you enjoy up to 5.1
channels of digital surround sound from Dolby Digital (AC-3) program
sources (such as Laserdisc software marked
DIGITAL
). Compared
with previous Dolby surround, Dolby Digital (AC-3) provides even
better sound quality, greater spatial accuracy, and improved dynamic
range.
Note
Although a full set of speakers (front left, right, and center, Surround
left and right, and a subwoofer) is required for true 5.1 channel Dolby
Digital (AC-3) surround sound, this AV CONTROL CENTER lets you
enjoy Dolby Digital (AC-3) (and Dolby Pro Logic) program sources,
even if you connect only the front speakers.
* LFE = Low Frequency Effects. This channel delivers separate non-
directional bass signals to the subwoofer for more dynamic deep
bass sound effects.
Although only Dolby Digital (AC-3) soundtracks incorporate a sepa-
rate low frequency channel, connecting a subwoofer will also
improve deep bass performance in the other surround modes.
Ambience effects
This AV CONTROL CENTER incorporates 7 different sound modes to let you enjoy surround sound with a wide variety of
program sources. The Dolby Digital (AC-3) and Dolby Pro Logic surround sound let you enjoy theater-like surround effects when
you play Dolby Digital (AC-3) and Dolby Surround program sources (like Laserdiscs and DVDs). Dolby 3 Stereo creates a
panoramic frontal sound field. The Digital Signal Processing (DSP) modes let you create a variety of different sonic
environments from almost any type of program source.
To obtain the best possible surround sound, be sure to complete "Setup for surround play (SET UP)" before using the surround
modes.

DTS
The DTS multi-channel audio format is available on CD, LD and DVD
software. DTS is a strictly digital format and can not be decoded inside
most CD, LD or DVD players. For this reason, if you attempt to listen
to DTS encoded software through the analog output of your CD, LD
or DVD player, you will experience digital noise in most cases. This
noise can be quite loud if the analog output is connected directly to a
high power amplification system. Proper measures for playing the
digital output as described below should be taken to avoid this
situation. To enjoy DTS Digital Surround playback, an external 5.1
channel DTS Digital Surround decoder system or an amplifier with a
built-in DTS Digital Surround decoder must be connected to the digital
output (S/P DIF, AES/EBU or TosLink) of a CD, LD or DVD player.
SRS Circle Surround
The Circle Surround System was developed to provide the highest
level of sonic performance available in a Matrix system. Audio for
music was not the focus for other multichannel formats and, as a
result, there is a serious compromise in the performance of these
systems. That is not to say that the Circle Surround system is only for
music–other applications such as Cinema, Home Theater, multichan-
nel broadcast, video tape and any other type of audio delivery can take
advantage of the superior performance of Circle Surround. Since
Circle Surround provides proper performance for music, the sonic
impact for all other applications is also improved. Circle Surround 5.1
is capable of delivering true five-channel impact.
