[. . . ] Arena 1/2 This mode provides the feeling of a live concert in a medium - sized (Arena 1) or large (Arena 2) arena. Matrix This mode reproduces a delayed signals from the surround channels to emphasize the sense of expansion for music sources. 17 ENGLISH For your reference, the sound from each channel can be reproduced according to the surround modes as follows: Channels Modes DTS FRONT L/R CENTER SURROUND L/R SURROUND BACK SUBWOOFER ENGLISH DTS ES DISCRETE/MATRIX DTS NEO MOVIE/MUSIC DOLBY DIGITAL DOLBY DIGITAL EX DOLBY PRO LOGIC DOLBY PRO LOGIC II MOVIE/MUSIC DOLBY VIRTUAL MPEG 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 "Adjusting the speaker settings" on page 19. ) 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 : 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. FRONT (LEFT) TV or SCREEN 1 SUBWOOFER CENTER 3 4 FRONT (RIGHT) 2 LISTENING POSITION 5 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. 6 SURROUND (LEFT) 7 SURROUND (RIGHT) 9 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. 8 SURROUND (BACK) Surround speaker Surround back speaker Point slightly downward Subwoofer The subwoofer reproduces powerful deep bass sounds. 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. Front speaker 60 to 90 cm 18 Adjusting the speaker settings · After you have installed this unit and connected all the components, you should adjust the speaker settings for the optimum sound acoustics according to your environment and speaker layout. Setting the type of speakers The composition of the signals output from the different channels and the frequency reponse are adjusted automatically according to the combination of speakers actually being used. Select "Large" or "Small" not according to the actual size of the speaker but according to the speaker's capacity for playing low frequency (bass sound below frequency set for the Crossover Frequency mode and below) signals. Large : Select this when connecting speakers that can fully reproduce sounds below crossover frequency(*) of your speaker. Small : Select this when connecting speakers that cannot fully reproduce sound below crossover frequency. When this setting is selected, sound below crossover frequency is assigned to the subwoofer or speakers which are set to "Large"(when not using a subwoofer). Yes / None : Select the desired depending on whether a subwoofer is connected or not. (*) : Crossover frequency is the frequency (Hz) below which the bass sound of each main speakers is to output from the subwoofer or from speakers which are set to "Large" (when not using a subwoofer). If the frequency range of your speaker is 80 Hz ~ 12 KHz, the crossover frequency is 80 Hz. If you do not know, try comparing the sound at both settings (setting the volume to a level low enough so as not to damage the speakers) to determine the proper setting. Depending or relationship between speakers, settings possible for each speaker are as follows: Front L/R Center Surr. Back Subwoofer Large Large Small None Small Small None None None Large Large Small Yes None or Small None Small None None None Large Large Small None Small Small None Small Small None None None Yes Small Small None Large Large Small None Small Small None Speaker distance settings When enjoying 5. 1 channel surround playback with Dolby Digital and DTS sources, it is ideal that the center and surround speakers should be the same distance from the main listening position as the front speakers. By entering the distance between the listening position and each speaker, the delay times of center and surround speakers are automatically adjusted to create an ideal listening environment virtually as if the center and surround speakers were at their ideal locations respectively as below: Ideal location of a center speaker FL SW C Dc FR All speakers should be located within a circle with a radius of Df Df : Distance between front speakers and listening position Dc : Distance between center speakers and listening position Ds : Distance between surround speakers and listening position Df Ds SL SB SR Ideal location of a surround speaker 19 ENGLISH Refer to the previous page and adjust the speaker settings · You can also adjust these settings with using the buttons on the front panel. (For details, refer to "SETTING UP THE SYSTEM ON FRONT PANEL" on page 43. ) Note : When the headphones are plugged or the 7 CH DIRECT is selected as an input source, the speaker setting function cannot be available.
