Ambience effects
This receiver is equipped with listening modes that allow
you to enjoy an enhanced sonic ambience with a variety of
video sources.
In order to obtain the optimum effect from the surround
modes, make sure to input the proper speaker settings
beforehand. *

Surround modes

Dolby Digital

The Dolby Digital surround format lets you enjoy up to 5.1 channels
of digital surround sound from Dolby Digital program sources (such as
Laserdisc or DVD software marked ). Compared with previ-
ous Dolby surround, Dolby Digital 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 surround sound, this receiver lets you enjoy Dolby Digital (and
Dolby Surround) 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 soundtracks incorporate a separate low
frequency channel, connecting a subwoofer will also improve deep
bass performance in the other surround modes.
The indication “LFE” appears in the display when a signal is being
input for this channel.

Dolby Digital EX

Dolby Digital EX is an extension of Dolby Digital technology, Dolby
Digital EX creates six full-bandwidth output channels from 6.1-channel
sources. This is done using a matrix decoder that derives three
surround channels from the two in the original recording.
This is achieved by using three different surround signals, surround left,
surround right, and surround back, each driving its own array of
speakers. Think of it as adding a center channel for the rear speakers,
which give more diffuse and natural surround effect, even if you
wanted the ability to completely encircle the audience with sound,
positioning sound effects exactly where they wolud be heard in real life.
For best results, Dolby Digital EX should be used with movie soundtracks
recorded with Dolby Digital Surround EX which contain a digital flag that
will automatically activate this feature. However, for titles released
prior to late 2001, this feature has to be activated manually.
Note
Although a full set of speakers (front left, right, and center, surround
left and right, surround back and a subwoofer) is required for true 6.1
channel Dolby Digital Surround EX sound, this receiver lets you enjoy
Dolby Digital (and Dolby Surround) 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 soundtracks incorporate a separate
low frequency channel, connecting a subwoofer will also improve
deep bass performance in the other surround modes.
The indication “LFE” appears in the display when a signal is
being input for this channel.

Dolby PRO LOGIC

II
Dolby Pro Logic II was designed specifically to provide a new sense
of spatiality, directionality and articulation of sounds from Dolby
Surround encoded sources (such as video and Laserdisc software
marked ). This is achieved with an intelligent, built-in
feedback logic design, a matrix surround decoding and the decoding
of stereo, full bandwidth surround outputs. The PRO LOGIC
II modes
programmed into this receiver are “MOVIE”, “MUSIC” and “PRO
LOGIC”. The “MOVIE” mode of the PRO LOGIC
II has preset
characteristics to produce a calibrated, high-level surround sound
playback while the “MUSIC” mode has user-adjustable characteris-
tics to offer the three optional controls, like “Dimension”, “Center
Width” and “Panorama” modes to allow optimization of the soundfields
as desired. The “Dimension” control allows the user to gradually
adjust the soundfield either towards the front or towards the rear; the
“Center Width” control allows various adjustment of the left-center-
right speakers’ balance; the “Panaroma” extends the front stereo
image to include the surround speakers for an exciting “wraparound”
effect with side wall imaging.
