Setting up LISTEN mode
What are LISTEN modes?
You can experience true home-theater sound with your new system. This system incorporates several listen modes to let you
enjoy surround sound with a wide variety of program sources. Each produces multiple channels of surround-sound, but each
does it differently.
● Dolby Digital: Dolby Digital uses an encode/decode process based on its theatrical digital surround sound technology. The five
main channels are full-frequency and independent, so sound can completely envelop you or soar anywhere in the room, just
like at the movies.
Compared with Dolby Pro Logic, Dolby Digital has more clarity, greater surround envelopment, and more realistic sound
movement between channels.
● Dolby Pro Logic/Dolby Pro Logic II: Dolby Pro Logic reproduces a surround sound like in a movie theater from Dolby Surround-
encoded program source (videotape or LaserDisc software carrying the Dolby Surround logo), and features excellent sound
movement on the front and a surrounding atmosphere of movie theaters. Meanwhile, Dolby Pro Logic II decodes a signal
encoded in 2 channels into 5-channel signals composed of the left/right front signals, center signal and surround left/right signals.
Dolby Pro Logic II is an advanced version of the decoding technology used with Dolby Pro Logic. It inputs 2-channel signals from
a Dolby Surround-encoded source and reproduces 5-channel signals in which the surround channel is divided into independent
channels for the left and right. Dolby Pro Logic II has the MOVIE mode and MUSIC mode, and the MUSIC mode enables
independent adjustment of three parameters including Panorama mode, Dimension and Center Width.
● DTS : DTS has five full-frequency channels that create effects nearly identical to those in a theater. Sounds seem to zoom from
one place to another or entirely surround you. Like Dolby Digital, DTS has much-improved clarity, surround and sound movement
capability compared with Dolby Pro Logic. This listen mode is available on CD, LD, and DVD media. DTS is a strictly digital format
that can be supplied only by a CD, LD, or DVD player that supports DTS sound.
● DSP (Digital Signal Processing): DSP allows you to create your own custom surround sound environments and use them with
any source (except Dolby Digital and DTS). You can select the ambience of an ARENA, JAZZ CLUB, THEATER, STADIUM or
DISCO to your taste.
● CS5.1 ch: 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, multichannel broadcast, video tape and any other type of audio delivery can take advantage of the
superior performance of Circle Surround.
● Stereo: Stereo listen mode provides standard stereo sound to the front left and right speakers.
Description of Dolby Pro Logic II: Music mode
Panorama mode : Expands the image of front-channel stereo to the surround speakers to create a sound environment that fills
your surroundings. (To change the Panorama mode, press SOUND key at the time of Dolby Pro Logic II Music
mode. Display the PANO R OFF or ON, then press the TRIM (5/∞) keys to select ON or OFF.)
Dimension : This controls the balance between the Front and Rear in 2 steps on the front and 2 steps on the rear. Set this
parameter to one of the Front steps if the surround effect is too strong, or to one of the Back steps if it is too
weak. (To change the Dimension, press SOUND key twice at the time of Dolby Pro Logic II Music mode.
Display the DIMEN 0 (or other value), then press the TRIM (5/∞) keys to select F-2, F-3, R-2 or R-3.)
Center Width : The center channel signal can be divided and distributed to the Front L/R channels.
The adjustment for distributing the center channel signal to the front channels can be applied in eight steps
from 0 to 7. Use this adjustment when the center image seems to be too strong. (To change the Center Width,
press SOUND key 3 times at the time of Dolby Pro Logic II Music mode. Display the C WIDTH 3 (or other
value), then press the TRIM (5/∞) keys to select 0 ~7.)
The INPUT/OUTPUT status indicator becomes an input indicator at the time of DOLBY
DIGITAL and DTS source and an output indicator at all other times.
