Advanced Sound Control
Sound Enhancement Systems
This receiver is equipped with several built-in sound enhancement
systems.
Dolby Digital
The Dolby Digital mode lets you enjoy full digital surround from
software processed in the Dolby Digital format. 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
EN from Dolby Pro Logic in that only four channels (Front Left, Front Right,
Center and Rear) are used, the new system provides stereo separation of
the rear speakers (Rear-Right, Rear-Left). Adding the subwoofer channel
to the 5 channels for bass sounds (counted as 0.1 channel) results in 5.1
channels (or 6 Channels) input Dolby Digital for that bring you the most
sophisticated sound enjoyment.
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 with any
stereo program
source (such as VCR/
TV) to enjoy multi-
channel sound
experience.

Stereo
The Stereo mode uses the two main channel outputs from the front
speakers and subwoofer speaker. Use this mode if you have connected
the front speakers only.
DSP (Digital Sound Processor)
These digital sound effects resemble sounds in a real environment such
as (HALL, CHURCH, STEREO, DOLBY PL EMULATION, DOLBY PL II MUSIC,
DOLBY PL II MOVIE). DSP automatically converts analog audio signals to
digital ones which enables you to adjust the sound without degrading
the sound quality. Different modes will give you different feels of size
and types of listening environment.

according to you needs. Four settings are available: BALANCE, STRONG,
POWERFUL and SOFT.
