JVC RX-E100SL Creating Realistic Sound Fields, Surround modes, Dolby Surround Dolby Pro Logic

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 receiver (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 receiver 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 receiver. (See page 6.)

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 receiver. (See page 6.)

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 Theater Surround

Used to reproduce sound tracks of the software encoded with Dolby

Surround ( DOLBY SURROUND ).

•Theater Surround cannot be used only when the front speakers and rear speakers are connected to this receiver (without respect to the center speaker connection).

Theater Surround can add acoustic surround effects (DAP mode effects) to Dolby Surround software, and create a sound field of a theater in your listening room.

•When Theater Surround is selected, the PRO LOGIC and DSP indicators light up on the display.
