Dolby Digital - Kenwood KRF-V6070D Mode D'emploi

Ambience effects

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
previous Dolby surround, Dolby Digital provides even better sound
quality, greater spatial accuracy, and improved dynamic range.
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.
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 would 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.
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.
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 characteristics
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 "Panorama" mode extends
the front stereo image to include the surround speakers for an
exciting "wraparound" effect with side wall imaging.
DTS mode
The DTS multi-channel audio format is available on CD, LD and DVD
software. DTS is a strictly digital format and cannot be decoded
inside most CD, LD or DVD players. For this reason, if you attempt
). Compared with
to listen to DTS encoded software through the analog output of your
new 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.
All models are incorporated with the DTS decoder.
DTS has a .1 or LFE channel.
The indication "LFE" appears in the display when a signal is being
input for this channel.
DSP mode
The DSP mode lets you add the atmosphere of a live concert or hall
to almost any type of program source. These modes are particularly
effective when used with stereo program sources, like CD, television,
and FM radio. You might enjoy trying the ARENA, JAZZ CLUB,
THEATER, STADIUM or DISCO mode the next time you watch a
concert or sporting event!
What's DSP?
DSP stands for Digital Signal Processor.
The way a sound is heard in an actual environment depends on a
variety of different factors. One of the most important is reverberation
(the act of decaying elements of sound echoing in various places).
The DSP modes produce the feeling of presence by using the DSP to
create reverberation, without spoiling the sound quality of the original
signal.
¢
DVD 6-channel mode
Using a DVD player or the like equipped with six (5.1) output channels
and the receiver, you can enjoy multi-channel encoded DVD source
material in all its splendor. Since the source signals are digital and
each channel is input independently, the resulting sound quality,
sense of spaciousness, and dynamic range are superb.
The indication "LFE" appears in the display during DVD 6-channel
mode selection.
