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 ). Compared with previous Dolby surround, Dolby Digital provides even better sound quality, greater spatial accuracy, and improved dynamic range.

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 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 IIx and 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.

Dolby Pro Logic IIx enhanced Dolby Pro Logic II’s features.

It creates 6.1 channel and 7.1 channel surround sound from stereo or

5.1channel signals. This feature provides you an astonishing ambi- ence effect which makes you feel you are surrounded by natural sound. Especially 7.1 channel surround sound can produce real back sound from Surround Back speakers.

The Pro Logic IIx modes programmed into this model are “Movie”, “Music” and “Game”. The Pro Logic II modes programmed into this model are “Movie”, “Music”, “Game” and “Pro Logic”. The “Movie” mode 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 “Dimen- sion”, “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.

The “Game” mode provides surrounded and exciting sound when you enjoy game or TV. Especially in Pro Logic IIx “Game” mode, base sound not only from Front and Center but also from Surround channel is added to Subwoofer. This provides ever more dynamic surround effects.

DSP mode

The DSP mode lets you add the atmosphere of a live concert or hall to almost any type of program source. 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. 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!

Dolby Virtual Speaker

The Dolby Virtual Speaker features a virtual surround sound field. This implements an effect as if there are multiple speakers in the listening room.

Dolby Headphone

When headphones are used in music listening, the audio of the left (or right) channel reaches only the left (or right) ear so the listener cannot feel the presence of acoustic images on the front.

The Dolby Headphone simulates a virtual room and include its acoustic characteristics in the left and right headphone signals. As a result, the listener can hear the same components as in speaker listening through the left and right years and therefore feel as if the sound source is located on the front of the listener.

Because of the same processing in "Pro Logic II Movie mode with Dolby Headphone" and "Pro Logic II Game mode with Dolby Head- phone", their respective effectiveness is the same.

DTS

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 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-ES

DTS-ES (Digital Theater System-Extended Surround) presents 6.1 channels surround system with additional Surround Back channel which evolved from the conventional 5.1 channels surround system. DTS-ES format that was recorded in DVD, CD or LD comprises of two modes. DTS-ES Discrete 6.1 produces the discrete surround back which is completely independent and DTS-ES Matrix 6.1 produces the surround back which synthesised within the left and right surround channels using matrix technology. DTS-ES has perfect compatibility with the conventional 5.1 channels surround system. 6.1 channels surround with an additional surround back presents a more natural presence and surround effects by increasing the impression of the sound image from back. Programs which are recorded using DTS-ES technology consist of information flags which will be able to control the Discrete and Matrix mode. Thus, it can automatically select the best matched mode.

Neo:6

Neo:6 is a new technology which was developed by DTS. It can produce high grade 6 channels surround with an astonishing fidelity from 2 channels content. Neo:6 has 2 modes, “Cinema” mode is for movie playback and “Music” mode is for music playback.

DTS 96/24

DTS 96/24 made it possible to achieve a wide frequency range of over 40 kHz by increasing the sampling frequency to 96 or 88.2 kHz. Moreover, DTS 96/24’s ability of 24 bit resolution offers the same frequency band and dynamic range as 96 kHz/24 bit PCM.

DTS 96/24 is, as with conventional DTS Surround, compatible with multi-channels. Therefore, sources recorded using DTS 96/24 technologies can be played in high sampling frequency, multichannel audio with ordinary DVDs and CDs.

DTS has a “.1” or “LFE” channel.

The indication “LFE” appears in the display when a signal is being input for this channel.

Note

LFE = Low Frequency Effects. This channel delivers separate non- directional bass signals to the subwoofer for more dynamic deep bass sound effects.
