Advanced Sound Control
Sound Enhancement Systems
This receiver is equipped with several built-in sound
enhancement systems.
Dolby Pro Logic II
The Pro Logic II mode uses the built-in circuit to steer the
Left, Center, Right and Surround left and right channel
audio signals and uses all five speakers to play both stereo
and Dolby Pro Logic program source, such as TV and VCR.
Dolby Pro Logic II includes Dolby Pro Logic II Movie, Dolby
Pro Logic II Music and Dolby Pro Logic Emulation.
You can use this mode to suit any stereo program source
(such as VCR / SAT) to enjoy multi-channel sound experi-
ence).
Dolby 3 Stereo
The 3 Stereo mode will redirect the Surround signals to the
front left and right speakers when only the front and
center speakers are used.
Dolby Digital
The Dolby Digital mode lets you enjoy full digital
surround from software processed in the Dolby Digital for-
mat. Dolby Digital provides better sound quality and a
more powerful presence than conventional Dolby
Surround.
This unit is equipped with Dolby Digital 5.1-channel so
that you can enjoy enhanced full digital surround sound.
Different from Dolby Pro Logic in that only four channels (
Front Left, Front Right, Centre and Rear ) are used, the new
system provides stereo separation of the rear speakers
(Rear-Right, Rear-Left ). Adding the to the 5 channels the
subwoofer channel for bass sounds (counted as 0.1 channel)
results in 5.1 channels (or 6 Channels) that bring you the
most sophisticated Dolby Digital sound enjoyment.
Digital Theater Systems (DTS) )
DTS is a digital surround system which delivers six channels
of master-quality, 20-bit audio. It offers five full-range
channels plus a special low frequency effect (LFE) channel
for subwoofer, resulting in what is commonly known as 5.1
channels. It can be applied with existing 5.1 speaker config-
urations.
DTS is available in DVD and CD mode.
