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 > 48 k

Digital PCM sources that are recorded at a sampling rate of greater than 48 kilohertz. This includes DVDs that are recorded with high quality audio.

c. PCM fs = 192 k

Digital PCM sources that are recorded at a sampling rate of 192 kilohertz. This includes 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

therefore recorded for 5.1-channel output.

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 4 dB. In other words, the source material that you are listening to has been recorded 4 dB 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 6.1-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 DVDs, compact discs, and LDs that have the mark.

f. MPEG Multi

Digital data with a maximum of 5.1-channel surround audio with MPEG compression. This source signal comes

from DVDs that have the mark.

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

2 channel digital signal (except for PCM) such as Dolby Digital. DVD or LD in which the 2 channel sound are recorded may be this type of input signal.

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

Monaural digital signal (except for PCM) such as Dolby Digital. DVD or LD in which the monaural sound are recorded may be this type of input signal.

Listening Modes

Mono

This mode is for playing old movies whose sound is recorded in monaural or playing left and right channels separately in the movies which contains the different language signals recorded into individual channels. This mode also allows you to listen to the multiplexed soundtracks on DVDs, and other media that have them.

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.

Subwoofer also can be used for playback.

T-D (Theater-Dimensional)

For the best enjoyment of your home theater, it is recommended that you have at least 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 D (Dolby Digital)

The Dolby D mode is used to play Dolby Digital sources.

Dolby Digital EX

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

Dolby EX

Select to achieve the same effects as Dolby Digital EX encoded sources with non-Dolby Digital sources.

DTS

The DTS mode is used to play DTS sources.

DTS 96/24

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

DTS-ES Discrete 6.1

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

DTS-ES Matrix 6.1

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.

MPEG Multi (MPEG Multichannel)

Used for playing MPEG multi channel source.
