Input Setup

Input source signals

a. Analog/PCM

Analog sources consist of LP records, AM and FM 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 > 48 k

Digital PCM sources that are recorded at a sampling rate of greater than 48 kilohertz. This includes compact discs and DVDs that are recorded with high quality au- dio.

c. PCM fs = 192 k

Digital PCM sources that are recorded at a sampling rate of greater than 192 kilohertz. This includes com- pact discs and DVDs that are recorded with extremely high quality audio.

d. Dolby D (Dolby Digital)

Digital data with AC-3 compression and a maximum of 5.1-channel surround sound. This source signal comes

from DVDs and LDs that have the mark and there-

fore recorded for 5.1-channel output. This source also comes from digital satellite broadcasts that support Dolby Digital.

Dial norm

Dialogue Normalization (Dial Norm) is 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 read Dial 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. For example, if you see the message “Dial Norm: +4” in the front panel display, to keep the overall output level constant just turn down the volume control by 4dB. In other words, the source material that you are listening to has been recorded 4dB louder than usual. If you do not see a message, then no adjustment of the volume control is necessary.

DOLBY DIGITAL

e. DTS

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

LDs that have the mark.

f. MPEG

Digital data with a maximum of 5.1-channel sur- round audio with MPEG compression. This source sig-

nal comes from DVDs that have the mark.

g. D.F. 2 ch

This corresponds to 2-channel digital format sources. This signal source comes from LDs, DVDs, and other digital sources that are recorded with 2-channel au- dio.

h. D.F. Mono

This corresponds to monaural digital format sources. This signal source comes from LDs, DVDs, and other digital sources that are recorded with monaural au- dio.

Listening Modes

Mono

This mode is for listening to the left and right channels separately. This mode also allows you to listen to the multiplexed soundtracks on DVDs, and other media that have them.

Stereo

This mode has all input sound is output from the left and right front speakers.

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.

Dolby D (Dolby Digital)

This mode is for listening to sources encoded with Dolby Digital in their plain format.

DTS

This mode is for listening to music DTS sources in their plain format.

DTS Film

This mode is for listening to cinema DTS sources in their plain format.

MPEG

This mode is for listening to music MPEG sources in their plain format.

MPEG Film

This mode is for listening to cinema MPEG sources in their plain format.

THX (THX Cinema)

Movies that have been encoded in Dolby Digital, DTS, MPEG, and Dolby Pro Logic can all benefit by activat- ing the THX mode. THX should be activated only when watching movies that were mixed for playback in large movie theater environments. THX need not be acti- vated for music, for movies that were made especially for television, or for shows such as sports programming, talk shows, and the like. This is because they were mixed in a small room environment.

For best results, use a THX certified speaker system.

•How to enjoy THX Surround EX

When the THX listening mode is selected, you can press the THX button on the remote controller to cycle through the settings “Auto,” “On,” and “Off.” When “Auto” is selected, if a Surround EX encoded source is input, it is automatically played in the THX Surround EX mode. When “On” is selected, all sur- round EX encoded sources and THX Surround EX playable sources (i.e., DTS-ES encoded sources) are played in the THX Surround EX mode. If the sound does not feel correct, set this to “Off.”

If “On” is selected and a source that cannot be played in the THX Surround EX mode, “THXCinema” appears in the front display. If “Off” is selected, the listening mode becomes THX Cinema.
