Creating Realistic Sound Fields
You can use the following DSP (Digital Signal Processor) modes to
reproduce a realistic sound field.
• Surround modes
• DAP modes
■
Surround modes
Surround modes cannot be used when only the front speakers
are connected to this unit (without the rear speakers or center
speaker).
Dolby Surround (Dolby Pro Logic)
*
Used to reproduce sound tracks of the software encoded with Dolby
Surround (
DOLBY SURROUND
).
Dolby Surround encoding format records the left front channel,
right front channel, center channel, and rear channel signals (total 4
channels) into 2 channels.
The Dolby Pro Logic decoder built in this unit decodes these 2
channel signals into original 4 channel signals — matrix-based
multichannel reproduction, and allows you to enjoy a realistic stereo
sound in your listening room.
• When Dolby Pro Logic is activated, the PRO LOGIC indicator
lights up on the display.
– Dolby Pro Logic will be activated for all 2 channel-encoded
software.
Dolby Digital
*
Used to reproduce multichannel sound tracks of the software
encoded with Dolby Digital (
).
• To enjoy the software encoded with Dolby Digital, connect the
source component using the digital terminal on the rear of this
unit. (See page 7.)
Dolby Digital encoding method (so-called discrete 5.1 channel
digital audio format) records and digitally compresses the left front
channel, right front channel, center channel, left rear channel, right
rear channel, and LFE channel signals (total 6 channels, but LFE
channel is counted as 0.1 channel. Therefore, called 5.1 channel).
Since each channel is completely independent from the other
channel signals to avoid interference, you can obtain much better
sound quality with much stereo and surround effects.
In addition, Dolby Digital enables stereo rear sounds, and sets the
cutoff frequency of the rear treble at 20 kHz, compared to 7 kHz for
Dolby Pro Logic. These facts enhance the sound movement and
being-there feelings much more than Dolby Pro Logic.
DTS Digital Surround
**
Used to reproduce multichannel sound tracks of the software
encoded with DTS Digital Surround (
).
• To enjoy the software encoded with DTS Digital Surround,
connect the source component using the digital terminal on the
rear of this unit. (See page 7.)
DTS Digital Surround is another discrete 5.1 channel digital audio
format available on CD, LD, and DVD software.
Compared to Dolby Digital, audio compression rate is relatively low.
This fact allows DTS Digital Surround format to add breadth and
depth to the reproduced sounds. As a result, DTS Digital Surround
features natural, solid and clear sound.
JVC Theatre Surround
Used to reproduce sound tracks of the software encoded with Dolby
Surround (
DOLBY SURROUND
).
• Theatre Surround can be used when the front speakers and
the rear speakers are connected to this unit (without regarding
the center speaker).
Theatre Surround can add acoustic surround effects (DAP mode
effects) to Dolby Surround software, and create a sound field of a
theatre in your listening room.
• When Theatre Surround is selected, the PRO LOGIC and DSP
indicators light up on the display.
