20 Dolby Pro Logic and Dolby 3 Stereo 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 system 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 one of Dolby Surround is selected, the PRO LOGIC indicator lights up on the display. Indications on the display for each surround •Dolby Digital •DTS Digital Surround •Dolby Pro Logic •Dolby 3 Stereo •DSP* *When you select FM/AM or AUX as the source, the Linear PCM indicator ( ) does not light up. —According to the speaker settings, some speaker indicators do not light up. In this case, set the speaker setting appropriately (see page 18.) Creating Realistic Sound Fields You can use the following surround to reproduce a realistic sound field. •Digital Multichannel Surround—Dolby Digital and DTS Digital Surround •Dolby Surround •DSP (Digital Signal Processor) modes Dolby Digital and DTS Digital Surround To enjoy surround effectively, all the speakers need to be connected and activated. Dolby Digital* Used to reproduce multichannel sound tracks of the software encoded with Dolby Digital ( ). 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. When the system detects Dolby Digital signals, the DOLBY DIGITAL indicator lights up on the display. DTS Digital Surround** Used to reproduce multichannel sound tracks of the software encoded with DTS Digital Surround ( ). 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. When the system detects DTS Digital Surround signals, the DTS indicator lights up on the display. Dolby Surround* Used to reproduce sound tracks of the VCR tapes encoded with Dolby Surround ( DOLBY SURROUND). This is only used for the sound sources coming through the AUX IN jacks. **Manufactured under license from Digital Theater Systems, Inc. US Pat.

21 SurroundMultichannelPro Logic* DSP (canceled)Surround Pro Logic 3 StereoTHEATER HALLLIVE CLUB DANCE CLUBSTEREO Analog Linear PCM Dolby Digital Multichannel Dolby Surround DTS Digital Surround DSP (Digital Signal Processor) Modes DSP modes have been designed to create important acoustic surround elements. The sound heard in a hall, a theater, a pavilion, a dance club, or a live 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 indirect sounds are important elements of the acoustic surround effects. The following DSP modes are provided with this unit. THEATER: Gives the feeling of a theater. HALL: Gives clear vocal and the feeling of a concert hall. LIVE CLUB: Gives the feeling of a live music club with a low ceiling. DANCE CLUB: Gives a throbbing bass beat. These DSP modes can be used to add the acoustic surround effects while reproducing stereo analog software or Linear PCM digital software, and can give you a real “being there” feeling. When one of the DSP modes is selected, the DSP indicator lights up on the display.To check the speaker connections and settings using the test tone 1. Select and play a DVD encoded with Dolby Digital or DTS Digital Surround. 2. Press TEST on the remote control. The test tone comes out from the speakers (except the subwoofer) in the order. • If there is a speaker from which no sounds comes out, check the speaker’s connection (see pages 7 and 8). 3. Press TEST again to stop the test tone. Input Signal format Available surround according to the input signal format : Possible: Impossible TEST Creating Realistic Sound Fields * You can use Pro Logic mode for all 2 channel sources, but surround effect does not work sufficiently except Dolby Surround encoded source.

27 Disc Introduction—DVD/VCD/CD •On some DVD or VCD/SVCD discs, their actual operations may be different from what is explained in this manual. This is due to the disc programming and disc structure, but not a malfunction of this system. •The following discs cannot be played back: –DVD-Audio, DVD-ROM, DVD-RAM, DVD-R, DVD-RW, CD-I, (CD-I Ready), Photo CD, etc. Playing back these discs will generate noise and damage the speakers. * Note on Video Format This unit accommodates the color system of NTSC. Note that the unit cannot playback the disc recorded with the color system of PAL. If a DVD recorded with the color system of PAL is loaded, “WRONG DISC” appears on the display and playback cannot start. ** Note on Region Code DVD players and DVD Video discs have their own Region Code numbers. This system only can play back DVD discs whose Region Code numbers include “1.” If a DVD with the inadequate Region Code numbers is loaded, “REGION ERR” appears on the display and playback cannot start. Disc Mark Video Region Code Type (Logo) Format*Number** DV D Video NTSC1 ALL Video CD This system has been designed to play back the following discs: DVD, Video CD, Super Video CD (SVCD), Audio CD, CD-R, and CD-RW. •This system can also play back MP3 files recorded on CD-Rs and CD-RWs. For in-depth information about what MP3, see “MP3 Introduction” on page 43. Discs you can play: Example 1: DVD disc Example 2 : Video CD/Audio CD Examples:Disc structure—DVD, Video CD (VCD/SVCD) and Audio CD (CD) A DVD disc consists of Titles, and each title may be divided into some Chapters. (See Example 1.) For example, if a DVD disc contains some movies, each movie may have its own title number, and it may be further divided into some chapters. On the other hand, a VCD/SVCD or CD consists of Tracks. (See Example 2.) In general, each song has its own track number. (On some discs, each track may also be divided by Indexes.) When playing back a VCD/SVCD with Playback Control (PBC) function, you can select what to view using the menu shown on the TV screen. (While operating a Video CD using the menu, some of the functions such as Repeat and Track Search may not work.) Notes on CD-R and CD-RW User-edited CD-Rs (Recordable) and CD-RWs (Rewritable) can be played back only if they are already “finalized.” •The system can play back CD-Rs or CD-RWs recorded on a personal computer if they have been recorded in the audio CD format or recorded in MP3 format (see page 43). However, they may not be played back depending on their characteristics or recording conditions. •Before playing back CD-Rs or CD-RWs, read their instructions or cautions carefully. •Some CD-Rs or CD-RWs may not be played back on this unit because of their disc characteristics, damage or stain on them, or if the built-in lens is dirty. •CD-RWs may require a longer readout time. This is caused by the fact that the reflectance of CD-RWs is lower than for regular CDs. If “” appears on the TV screen when pressing a button, the disc cannot accept an operation you have tried to do, or information required for that operation is not recorded in the disc. NOTICE : In some cases, without showing “ ,” operations will not be accepted. IMPORTANT: Before performing any operations, make sure of the following.... •Check the connection with the TV. •Turn on the TV and select the correct input on the TV to view the pictures or on-screen indications on the TV screen. •For DVD playback, you can change the Setup menu setting to your preference.
