Integra DTR-8.3 instruction manual Input source signals, Listening Modes

Input Setup

Input source signals

a. Analog/PCM

Analog sources consist of LP records, FM and AM broadcasts, cassette tapes, and the such. PCM (Pulse Code Modulation) is one form of digital audio signals and is recorded directly onto compact discs and DVDs without compression.

b. PCM fs=96k

Digital PCM sources recorded with a sampling rate of 96 kHz.

c. Dolby D (Dolby Digital)

Dolby Digital is compressed digital data with a maximum of 5.1- channel surround sound. This source signal comes from DVDs and

LDs that have the mark and therefore recorded for 5.1-channel output.

Dialog norm

Dialogue Normalization (Dialog Norm) is a feature of Dolby Digital. When playing back software that has been encoded in Dolby Digital, sometimes you may see a brief message in the front panel display that reads Dialog Norm xdB (“x” being a numeric value). Dialogue Normalization serves to let you know if the source material has been recorded at a higher or lower level than usual. This data is automatically used by the Dolby Digital decoder to adjust the output volume of the source material without affecting the volume of your amplifier. Therefore, even if source material volume changes, you will not have to adjust the volume on your amplifier.

d. DTS

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.

e. D.F. 2 ch (Digital Format 2 channel)

2-channel digital signals (not including PCM) such as Dolby Digital. DVDs or LDs recorded with 2-channel sound may be this type of input signal.

f. D.F. Mono (Digital Format Monaural)

Monaural digital signals (not including PCM) such as Dolby Digital. DVDs or LDs recorded with monaural sound may be this type of input signal.

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 of movies separately that contain different language signals. This mode also allows you to listen to the multiplexed soundtracks on DVDs, and other media that have them.

Pure Audio

Same as the direct mode except that the pure audio mode also turns off the display window and on screen display, turns off the power supply to the video circuitry, and minimizes the sources of noise. The result is high-fidelity music playback true to the original source.

Note for Australian model:

In the Pure Audio mode, if any component video signal is presented on the COMPONENT VIDEO INPUT2 jack, it will be output to the COMPONENT OUTPUT jack.

Direct

This mode delivers pure sound with minimum sound quality 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

This mode has 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 recommended that you have front left and right speakers, a center 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 position (sweet spot). Refer to the explanation of the listening 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

Opposed to Dolby Pro Logic, which had four channels (front left/ right, center, and surround) recorded into two channels with matrix processing and then played back in four channels, Dolby Pro Logic

IIuses a feedback logic circuit to have 5.1-channel surround audio (Dolby Surround, etc.) matrix-encoded into two channels 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 frequency 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 compact discs and other stereo sources.
