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.
G 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.
G 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.
G 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.
G 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.
G SRS CS II (Circle Surround II): Circle Surround II™ improves on its predecessor Circle Surround (CS-5.1) by enabling you to
experience powerful multi-channel surround sound playback from mono, stereo or Dolby Surround encoded audio and video
sources. You already enjoy listening to Dolby Digital and DTS multi-channel sound through your multiple speakers. Now, with
CS II you can also listen to audio CDs, MDs, television and radio broadcasts in full surround sound. You will discover a new type
of sound experience through SRS Circle Surround II.
The CS system dramatically reduces storage space requirements for multi-channel content. It creates a listening environment
that places the listener "inside" music performances, and dramatically improves both hi-fi audio and conventional surround
encoded video material. In addition, the CS II decoder includes patented SRS Dialog Clarity Enhancement ™ and TruBass ™
technologies. When translated over home theater, dialog mixed for the cinema may become difficult to understand and SRS
Dialog Clarity solves this problem by improving dialog clarity, even when playing back Dolby Digital or DTS sources. TruBass
creates rich, deep bass in small speaker systems without the need for a subwooder.
G Stereo: Stereo listen mode provides standard stereo sound to the front left and right speakers.

DTS disclaimer clause
DTS Digital Surround™ is a discrete 5.1 channel digital audio format available on CD, LD, and DVD software which consequently cannot be
decoded and played back inside most CD, LD, or DVD players. For this reason, when DTS-encoded software is played back through the
analog outputs of the CD, LD, or DVD player, excessive noise will be exhibited. To avoid possible damage to the audio system, proper
precautions should be taken by the consumer if the analog outputs are connected directly to an amplification system. To enjoy DTS Digital
Surround™ playback, an external 5.1 channel DTS Digital Surround™ decoder system must be connected to the digital output (S/P DIF,
AES/EBU, or TosLink) of the CD, LD or DVD player.
This unit is equipped with DTS Digital Surround™ decoder.
