JVC RX-778VBK manual Using the DSP Modes, 3D-PHONIC modes, DAP modes

Using the DSP Modes

The built-in Surround Processor provides three types of the DSP (Digital Signal Processor) mode — 3D-PHONIC mode, DAP (Digital Acoustic Processor) mode and Surround mode.

3D-PHONIC modes

The 3D-PHONIC mode gives you such a nearly surround effect as it is reproduced through the Dolby Surround decoder, which is widely used to reproduce sounds with a feeling of movement like those experienced in movie theaters. The 3D-PHONIC mode is the result of research on sound localization technology carried out at JVC for many years. This mode can be used when the front speakers are connected to this receiver (without respect to the rear/center speaker connection).

•You can select either 3D ACTIONor 3D THEATER to your preference when playing an analog or Linear PCM (digital) source.

•You can select either 3D DIGITALor 3D THEATER to your preference when playing a Dolby Digital source.

3D ACTION: Best for action and war movies — where the action is fast and explosive.

3D DIGITAL: Reproduces multi-sound source encoded with Dolby Digital.

3D THEATER: Reproduces the sound field of a large theater. This mode can be selected when only front speakers are connected to this receiver and “REAR SPK” and “CENTER SPK” is set to “NONE” (see page 14).

Note on the subwoofer sound when using the 3D-PHONIC modes

Sounds will or will not come out of the subwoofer according to the selected 3D-PHONIC mode.

•With “3D ACTION” selected: No sound comes out.

•With “3D DIGITAL” selected: Sound comes out if the subwoofer channel signals come into this receiver ( LFE of the signal indicators lights up — see page 10) while playing a multi-sound source encoded with Dolby Digital.

•With “3D THEATER” selected:

–If “FRONT SPK” is set to “SMALL,” sound comes out while playing any source.

–If “FRONT SPK” is set to “LARGE,” sound comes out only if the subwoofer channel signals come into this receiver ( LFE of the signal indicators lights up — see page 10) while playing a multi-sound source encoded with Dolby Digital.

DAP modes

The sound heard in a concert hall or club 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 DAP mode can create these important elements, and gives you a real “being there” feeling. This mode can be used when the front

speakers are connected to this receiver (without respect to the rear/center speaker connection).

You can select one of the following to your preference.

LIVE CLUB: Gives the feeling of a live music club with a low ceiling.

DANCE CLUB: Gives a throbbing bass beat.

HALL: Gives clear vocal and the feeling of a concert hall.

PAVILION: Gives the spacious feeling of a pavilion with a high ceiling.
