[. . . ] The surround channel is monaural, but is played through both surround speakers. Dolby Pro Logic II surround This mode applies conventional 2- channel signals such as digital PCM or analog stereo signals as well as Dolby Surround signals, etc. to surround processing to offer improvements over conventional Dolby Pro Logic circuits. Dolby Pro Logic II surround includes two modes as follows: Dolby Pro Logic II Cinema When enjoying movies, this mode allows you to further enhance the cinematic quality by adding processing that emphasizes the sounds of the action special effects. Dolby Pro Logic II Music When listening to music, this mode allows you to further enhance the sound quality by adding processing that emphasizes the musical effects. The following modes apply conventional 2-channel signals such as digital PCM or analog stereo signals to high performance Digital Signal Processor to recreate sound fields artificially. Select one of the three provided surround modes according to the program source you want to play. Theater This mode provides the effect of being in a movie theater when watching a movie. Hall This mode provides the ambience of a concert hall for classical music sources such as orchestral, chamber music or an instrumental solo. Matrix This mode reproduces a delayed signals from the surround channels to emphasize the sense of expansion for music sources. Dolby Virtual This mode employs sophisticated digital processing to create the illusion of "phantom" speakers, this mode allows you to experience surround sound effects from Dolby Digital, Dolby Surround or 2-channel (recorded in digital PCM or analog stereo) sources, through just a single pair of front speakers. "Dolby", "Pro Logic", and the double-D symbol are trademarks of Dolby Laboratories. For your reference, the sound from each channel can be reproduced according to the surround modes as follows: Channels Modes DTS DTS ES DISCRETE/MATRIX DTS NEO:6 MOVIE/MUSIC DOLBY DIGITAL DOLBY DIGITAL EX DOLBY PRO LOGIC DOLBY PRO LOGIC II CINEMA/MUSIC DOLBY VIRTUAL MATRIX Other Surround STEREO 7 CH DIRECT · Depending on the speaker settings and the number of the encoded channels, the sound from the corresponding channels cannot be reproduced.

For details, refer to the operating instructions of the component to be connected. Speaker placement Ideal speaker placement varies depending on the size of your room and the wall coverings, etc. The typical example of speaker placement and recommendations are as follows : 2 3 1 4 5 ENGLISH Front left and right speakers and center speaker Place the front speakers with their front surfaces as flush with TV or monitor screen as possible. Place the center speaker between the front left and right speakers and no further from the listening position than the front speakers. Place each speaker so that sound is aimed at the location of the listener's ears when at the main listening position. 6 9 7 Surround left and right speakers Place the surround speakers approximately 1 meter (40 inches) above the ear level of a seated listener on the direct left and right of them or slightly behind. Surround back speaker Place the surround back speaker at the rear center facing the front at a slightly higher position (0 to 10 inches) than the surround speakers. We recommend installing the surround back speaker at a slightly downward facing angle. This effectively prevents the surround back channel signals from reflecting off the TV or screen at the front center, resulting in interference and making the sense of movement from the front to the back less sharp. 1. Listening position Subwoofer The subwoofer reproduces powerful deep bass sounds. Place a powered subwoofer anywhere in the front as desired. Surround speaker Notes : When using a conventional TV , to avoid interference with the TV picture, use only magnetically shielded front left and right and center speakers. To obtain the best surround effects, the speakers except the subwoofer should be full range speakers.
