About other digital signals

Linear PCM—Uncompressed digital audio data used for DVDs, CDs, and Video CDs

DVDs support 2 channels with sampling rates of 48/96 kHz, at quantization of 16/20/24 bits. On the other hand, CDs and Video CDs are limited to 2 channels with 44.1 kHz at 16 bits.

•When Linear PCM signal is detected, the LINEAR PCM indicator lights up.

Multi-channelPCM—Uncompressed multi-channel digital audio data used for DVD-Audios

DVD-Audios support up to 5.1 channels with sampling rates of 44.1/48/88.2/96 kHz and 2 channels with sampling rates of 44.1/48/88.2/96/176/192 kHz, at quantization of 16/20/24 bits.

•When the Multi-channel PCM signal is detected, the LINEAR PCM indicator lights up and “MULTI CH PCM” appears on the display for a while.

Dual Mono

Dual Mono can be easily understood when you think of the bilingual broadcast for TV programs (however, the Dual Mono format is not identical with those analog formats). This format is now adopted in Dolby Digital, DTS, and so on. It allows two independent channels (called main channel and sub-channel) to be recorded separately.

•You can select either channel you want to listen to (see page 32).

7 Digital Acoustic Processor (DAP) modes

You can use the following DAP modes in order to reproduce a more acoustic sound field in your listening room.

HALL1	Reproduces the spatial feeling of a large
	shoebox-shaped hall designed primarily for
	classical concerts. (Its seating capacity is about
	2000.)
HALL2	Reproduces the spatial feeling of a large
	vineyard-shaped hall designed primarily for
	classical concerts. (Its seating capacity is about
	2000.)
LIVE CLUB	Reproduces the spatial feeling of a live music
	club with a low ceiling.

DANCE CLUB Reproduces the spatial feeling of a rocking dance club.

PAVILION Reproduces the spatial feeling of an exhibition hall with a high ceiling.

THEATRE1 Reproduces the spatial feeling of a large theater where the seating capacity is about 600.

THEATRE2 Reproduces the spatial feeling of a small theater where the seating capacity is about 300.

NOTE

When “THEATRE1” or “THEATRE2” is activated while playing back 2-channel analog or digital source, the built-in Dolby Pro Logic II

decoder is activated and the indicator lights up.

Introducing the DSP modes

The sound heard in a concert hall, club, etc. consists of direct sound and indirect sound—early reflections and reflections from behind. Direct sounds reach the listener directly without any reflection. On the other hand, indirect sounds are delayed by the distances of the ceiling and walls. These direct sounds and indirect sounds are the most important elements of the acoustic surround effects.

The DSP modes can create these important elements, and give you a real “being there” feeling.

Reflections from behind

Early reflections

Direct sounds

The DSP modes include the following modes:

•Digital Acoustic Processor (DAP) modes—HALL1, HALL2,

LIVE CLUB, DANCE CLUB, PAVILION, THEATRE1, THEATRE2

•MONO FILM—Used for all types of 2-channel signals (including Dual Mono signal)

•All Channel Stereo mode (ALL CH STEREO)

When one of the DSP modes is activated, the DSP indicator lights up on the display.

When using the DAP mode, the sounds come out of all the connected and activated speakers.

•If “SURROUND SPK” is set to “NO” in the speaker setting (see page 30), JVC’s original 3D-PHONIC processing (which has been developed to create the surround effect through the front speakers only) is used.

The 3D-PHONIC indicator lights up on the display.

7 MONO FILM

In order to reproduce a more acoustic sound field in your listening room while viewing monaural sound video software (analog and 2-channel digital signals including Dual Mono signal), you can use this mode.

The surround effect will be added, and the sound localization of actor’s words will be improved.

This mode cannot be used for multi-channel digital signals.

When “MONO FILM” is used, sounds come out of all the connected (and activated) speakers.

•If “SURROUND SPK” is set to “NO” in the speaker setting (see page 30), JVC’s original 3D-PHONIC processing (which has been developed to create the surround effect through the front speakers only) is used.

The 3D-PHONIC indicator lights up on the display.

•If incoming signals change from 2-channel digital signal to another digital signal type, “MONO FILM” is canceled and an appropriate Surround mode is activated.
