Integra DTR-7.4 Using the Listening Modes, Mono, Pure Audio, Direct, Stereo, Dolby Pro Logic

Using the Listening Modes

The DTR-7.4’s surround sound enables you to enjoy movie theater or concert hall quality sound in your home.

The configuration of the speakers is very important for the surround sound effect. Refer to “About Home Theater” on page 16.

Before selecting a listening mode, be sure to complete the Speaker Setup (See page 32). Once the parameters have been set, it is not necessary to set them again. See pages 44-45 for information regarding how to select the listening mode.

Listening Modes

Mono

This mode is for playing old movies where the sound is recorded in monaural or for playing the left and right channels separately for movies that contain different lan- guage signals. This mode also allows you to listen to the multiplexed soundtracks on DVDs and other media that have them.

Pure Audio

The same as the direct mode except that the pure audio mode also turns off the display window, turns off the power supply to the video circuitry (resulting in a blacked-out screen), and minimizes the sources of noise. The result is high-fidelity music playback true to the original source.

Direct

This mode delivers pure sound with minimal sound qual- ity adjustment and filtration. The sound recorded for the right and left front channels is output to the right and left front speakers only and not output to the subwoofer.

Stereo

All input sound is output from the left and right front speakers.

The subwoofer is also used for playback.

T-D (Theater-Dimensional)

For the best enjoyment of your home theater, it is recom- mended that you have front left and right speakers, a cen- ter speaker, and surround left and right speakers.

However, if you only have front left and right speakers, you can enjoy multichannel audio by using this mode. This mode controls the characteristics of the sound that reaches each ear to reproduce a multi-speaker setup. To receive the full effect, there is an optimum listening posi- tion (sweet spot). Refer to the explanation of the listen- ing angle. In addition, if the reflective sound components are large, it may be difficult to achieve the desired result, so be sure to set up your system and listening position to minimize reflective sound.

Dolby Pro Logic II

As opposed to Dolby Pro Logic, which had four chan- nels (front left/right, center, and surround) recorded into two channels with matrix processing and then played back in four channels, Dolby Pro Logic II uses a feed- back logic circuit to have 5.1 channel surround audio (Dolby Surround, etc.) matrix-encoded into two chan- nels and then played back in its original 5.1 channel form.

Dolby Pro Logic II provides a Movie Mode designed for playing movies and a Music Mode designed for listening to music.

In the Movie Mode, the surround channels, which used to provide monaural output over only a narrow fre- quency range, now provide complete stereo output over the full frequency range. The result is movie viewing with a realistic feel of movement. This mode can be used with VHS and DVD videos with the mark and certain television programs.

The Music Mode uses the surround channels to provide a natural soundfield that cannot be provided with normal stereo output. This mode can be used with music com- pact discs and other stereo sources.

Dolby D (Dolby Digital)

This mode is used for playing Dolby Digital sources. Dolby Digital is compressed digital data with a maxi- mum of 5.1 channel surround sound. This source signal

comes from DVDs and LDs that have the mark and therefore are recorded for 5.1 channel output.

• Dolby Digital EX

Enabled when playing back sources with surround tracks that were encoded using the Surround EX technology.

DTS Neo:6

This mode is for 6.1 channel playback of sources such as PCM or analog sources that have only two channels. The outputs of all six channels have a wide frequency range with a great separation between the different channels. This mode can be set to the Cinema Mode designed for playing movies and the Music Mode designed for listen- ing to music.

The Cinema Mode is good for movies. The reproduced surround sound provide the same realistic feel of move- ment as 6.1 channel sources. This mode can be used with VHS and television programs with stereo sound.

The Music Mode uses the surround channels to provide a natural sound space that cannot be provided with nor- mal stereo output. This mode can be used with music CDs and other stereo sources.

DTS

This mode is used for playing DTS sources.

DTS (Digital Theater System) is compressed digital data with a maximum 5.1 channel surround output (6.1 channel with DTS-ES Discrete sources) that allows for an extremely high-quality sound. This source signal requires a DVD player that supports DTS output and comes from

DVDs, compact discs, and LDs that have the mark.
