Integra DTR-7.4 instruction manual Using the Listening Modes

Using the Listening Modes—Continued

•DTS-ES Discrete

With the addition of the surround back channel, this new format has all 6.1 channels recorded indepen- dently for a completely discrete digital format. Since all channels are recorded independently, high-fidel- ity surround playback with an increased feeling of a separated sound space is achieved.

• DTS-ES Matrix

This format has the surround back channel matrix encoded and inserted into the left and right surround channels so that at playback the output for the left, right, and back surround channels are decoded using a high-precision matrix decoder.

• DTS 96/24

Automatically changes to this mode when playing back sources with surround tracks that were encoded using the DTS 96/24 technology.

THX

THX is an exclusive set of standards and technologies established by the world-renowned film production com- pany, Lucasfilm Ltd. THX grew from George Lucas’ personal desire to make your experience of the film soundtrack, in both movie theaters and in your home the- ater, as faithful as possible to what the director intended. Movie soundtracks are mixed in special movie theaters called dubbing stages and are designed to be played back in movie theaters with similar equipment and conditions. This same soundtrack is then transferred directly onto LD, VHS tape, DVD, etc., and is not changed for play- back in a small home theater environment.

THX engineers developed patented technologies to translate accurately the sound from the movie theater environment into the home, correcting the tonal and spa- tial errors that occur. On this product, when the THX indicator is on, THX features are automatically added in Cinema Modes (e.g. THX Cinema, THX Surround EX).

• THX Cinema

This is the conventional 5.1 channel THX format. This mode should be used only when playing back sources that were mixed for playback in large movie theater environments.

• THX Surround EX

“THX Surround EX - Dolby Digital Surround EX” is a joint development of Dolby Laboratories and the THX division of THX Ltd.

In a movie theater, film soundtracks that have been encoded with Dolby Digital Surround EX technol- ogy are able to reproduce an extra channel which has been added during the mixing of the program. This channel, called Surround Back, places sounds behind the listener in addition to the currently avail- able front left, front center, front right, surround right, surround left, and subwoofer channels.

This additional channel provides the opportunity for more detailed imaging behind the listener and brings more depth, spacious ambience, and sound localiza- tion than ever before.

When released to the home consumer market, mov- ies that were created using the Dolby Digital Sur- round EX technology, may have a note to that effect on the packaging. A list of movies created using this technology can be found on the Dolby web site at http://www.dolby.com.

The DTR-7.4 can play the 5.1 channel sources in THX surround EX mode, even if the source is not encoded in Dolby Digital Surround EX format. In this case, the sound actually output from the sur- round back channels depends on the source and may not fit your tastes.

Digital Signal Processing (DSP) modes

Mono Movie

This mode is suitable for playing back monaural record- ing such as old movie soundtracks. The center channel delivers the unprocessed original sound, whereas the other channels deliver the center-channel sound pro- cessed with the appropriate reverberation. This allows you to enjoy monaural sound with the atmosphere of a movie theater.

Enhance

This mode reproduces a natural surround environment by using seven speaker channels. The sound effects move smoothly toward the surround back. This mode is good for music and TV sports programs.

Orchestra

This mode is appropriate for classical and opera music. The center channel is cut and the surround channels are emphasized to widen the stereo image. It will simulate the natural reverberation that is created in large halls.

Unplugged

This mode is suitable for acoustical instrumental sounds, vocals, and jazz music. By emphasizing the front stereo image, it will simulate the acoustics that you would experience in front of the stage.

Studio-Mix

This mode is for rock and popular music. The lively sounds are enhanced for a powerful acoustic image that simulates the feeling of being at a club or rock concert.

TV Logic

This mode gives realistic acoustics to TV programs that are aired from TV studios. It enhances the entire sur- round sound and clarity of the conversation.

All Ch Stereo

This mode is designed for playing background music. The front, surround, and surround back channels create a stereo image that encompasses the entire area.
