■Dolby Surround

Dolby Pro Logic II

Dolby Pro Logic II is a multi-channel playback format to convert 2-channel software into 5-channel (plus subwoofer). The matrix- based conversion method used for Dolby Pro Logic II makes no limitation for the cutoff frequency of the surround treble and enables stereo surround sound.

•This receiver provides two types of Dolby Pro Logic II modes— Pro Logic II Movie (PLII MOVIE) and Pro Logic II Music (PLII MUSIC).

When Dolby Pro Logic II is activated, the indicator lights up on the display.

PLII MOVIE Suitable for playing any Dolby Surround encoded software. You can enjoy a sound field very close to the one created with discrete 5.1-channel sounds.

PLII MUSIC Suitable for playing any 2-channel stereo software. You can enjoy wide and deep sounds.

•To enjoy software encoded with Dolby Digital, connect the source component using the digital terminal on the rear of this receiver. (See page 11.)

■DTS**

DTS is another digital signal compression method, developed by Digital Theater Systems, Inc., and enables multi-channel encoding and decoding (1ch up to 6.1ch).

•When DTS signal is detected through the digital input, the DTS indicator lights up on the display.

DTS Digital Surround

DTS Digital Surround (DTS) is another discrete 5.1 channel digital audio format available on CD, LD, and DVD software. Compared to Dolby Digital, the DTS Digital Surround format has a lower audio compression rate which enables it to add breadth and depth to the sounds reproduced. As such, DTS Digital Surround features natural, solid, and clear sound.

Another multi-channel digital surround encoding format introduced by Digital Theater Systems, Inc. is DTS Extended Surround

(DTS-ES).

It greatly improves the 360-degree surround impression and space expression by adding the third surround channel—surround back channel.

DTS-ES includes two signal formats with different surround signal recording methods—DTS-ES Discrete 6.1ch and DTS-ES Matrix 6.1ch.

•You can use the Virtual Surround Back (see page 22) when playing back DTS-ES software. This function creates the great surround effect from the behind as if you have connected the surround back speaker. The VIRTUAL SB indicator lights up on the display.

DTS 96/24

In recent years, there has been increasing interest in higher sampling rates both for recording and for reproducing at home. Higher sampling rates allow wider frequency range and greater bit depths provide extended dynamic range.

DTS 96/24 is a multi-channel digital signal format (fs 96 kHz/24 bits) introduced by Digital Theater Systems, Inc. to deliver “better- than-CD sound quality” into the home.

•When DTS 96/24 signal is detected, the DTS and 96/24 indicators light up. You can enjoy its 5.1-channel sound with full- quality.

**“DTS” and “DTS 96/24” are trademarks of Digital Theater Systems, Inc.

When using Surround mode, the sounds come out of the activated speakers which the Surround mode requires.

•If either the surround speakers or center speaker is set to “NO” in the speaker setting (see page 21), the corresponding channel signals are allocated to and emitted through the front speakers.

•If both the surround speakers and center speaker are set to “NO” in the speaker setting (see page 21), JVC’s original 3D- PHONIC processing (which has been developed to create the surround effect through the front speakers only) is used. The 3D indicator lights up on the display.

3D HEADPHONE mode

If you connect a pair of headphones while one of the Surround modes is in use, the 3D HEADPHONE mode is activated without respect to the type of software played back. “3DHEADPHONE” appears on the display and the DSP, 3D, and HP indicators light up.

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 LPCM indicator lights up.

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 analogue 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 22).
