39■ Dolby SurroundDolby Pro Logic IIDolby Pro Logic II is a multi-channel playback format to convert2-channel software into 5-channel (plus subwoofer). The matrix-based conversion method used for Dolby Pro Logic II makes nolimitation for the cutoff frequency of the surround treble andenables 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 (PLIIMUSIC).When Dolby Pro Logic II is activated, the indicator lightsup on the display.PLII MOVIE Suitable for playing any Dolby Surround encodedsoftware. You can enjoy a sound field very closeto the one created with discrete 5.1-channelsounds.PLII MUSIC Suitable for playing any 2-channel stereosoftware. You can enjoy wide and deep sounds.• To enjoy software encoded with Dolby Digital, connect thesource component using the digital terminal on the rear of thisreceiver.

As such, DTS Digital Surroundfeatures natural, solid, and clear sound.Another multi-channel digital surround encoding format introducedby Digital Theater Systems, Inc. is DTS Extended Surround(DTS-ES).It greatly improves the 360-degree surround impression andspace expression by adding the third surround channel—surroundback channel.DTS-ES includes two signal formats with different surround signalrecording methods—DTS-ES Discrete 6.1ch and DTS-ES Matrix6.1ch.• You can use the Virtual Surround Back (see page 22) whenplaying back DTS-ES software. This function creates the greatsurround effect from the behind as if you have connected thesurround back speaker. The VIRTUAL SB indicator lights up onthe display.DTS 96/24In recent years, there has been increasing interest in highersampling rates both for recording and for reproducing at home.Higher sampling rates allow wider frequency range and greater bitdepths provide extended dynamic range.DTS 96/24 is a multi-channel digital signal format (fs 96 kHz/24bits) 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 96/24indicators light up. You can enjoy its 5.1-channel sound with full-quality.** “DTS” and “DTS 96/24” are trademarks of Digital TheaterSystems, Inc.When using Surround mode, the sounds come out of theactivated 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 correspondingchannel signals are allocated to and emitted through the frontspeakers.• 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 thesurround effect through the front speakers only) is used. The 3Dindicator lights up on the display.3D HEADPHONE modeIf you connect a pair of headphones while one of the Surroundmodes is in use, the 3D HEADPHONE mode is activatedwithout 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 signalsLinear PCMUncompressed digital audio data used for DVDs, CDs, andVideo CDs.DVDs support 2 channels with sampling rates of 48/96 kHz, atquantization of 16/20/24 bits. On the other hand, CDs andVideo CDs are limited to 2 channels with 44.1 kHz at 16 bits.• When Linear PCM signal is detected, the LPCM indicatorlights up.Dual MonoDual Mono can be easily understood when you think of thebilingual broadcast for TV programs (however, the Dual Monoformat is not identical with those analogue formats).This format is now adopted in Dolby Digital, DTS, and so on. Itallows two independent channels (called main channel andsub-channel) to be recorded separately.• You can select either channel you want to listen to (seepage 22).
