[. . . ] Lastly, gently pull the midsection of the speaker grille toward you to remove it. To replace the grille, push the projections at the six locations into the grille plug holes on the speaker cabinet. · The grille was designed to enhance the sound quality, so be careful not to tear or damage it when removing or replacing it. R FRONT SPEAKERS A B L R L + ­ + ­ Speaker terminals on AV amplifier Before turning on the amplifier's power switch: · Make sure that the positive (+) and negative (-) speaker cables do not contact each other. Otherwise, a shortcircuit may occur, causing damage to the amplifier. · Be sure to connect the speaker cables with correct polarity (connect the speaker's positive (+) and negative (-) binding posts with the amplifier's corresponding speaker terminals). Reversed polarity results in impaired bassrange reproduction, causing mislocalization of the sound image. Also, be sure to connect the Right and Left speakers with the amplifier's corresponding speaker terminals. · Pull lightly on the speaker cables to ensure that they are connected firmly. Removal Replacement Placement The sound quality a speaker system reproduces varies greatly depending on the construction and area of the room where it is installed, as well as the location and size of the furniture. For better-quality sound, observe the following precautions. · It is recommended not to place the speakers on blocks, but place the speakers on a sturdy floor or surface that does not transmit vibrations. It is especially important to refrain from placing the speakers on shag carpeting for the speakers may tip over and the sound quality will be adversely affected. Moreover, high-quality bass sound cannot be obtained if the speakers are not seated stably on the floor. Insert coins or other thin discs to seat the speakers stably. As a general rule, having the speakers resting on a number of points provides better sound than having it rest completely on one surface. If the bass sounds are low, place the speakers close to the wall behind it to prevent the bass sounds from escaping. You can then obtain the desired bass level by adjusting how far from the wall the speakers are placed. · In many rooms, the furniture and wall affect the reproduced sound quality. For stereo sound reproduction, placing the Right and Left speakers in the same condition produces the best results. If they are placed in extremely different conditions, the Right- and Left-channel balance will be adversely affected. · The ideal placement of the speaker system is as follows: Imagine an equilateral triangle and position the Right and Left speakers on both ends of the base. The ideal listening position is at or slightly to the rear of the triangle apex. · Glazed doors or surrounding walls in front of the speaker system may cause the resonance of specific frequency ranges due to reflected sound. [. . . ] Otherwise, the objects may be attracted, causing injury or damaging the diaphragm. Rear of the speaker Screw Driver Base extension Speaker care Wipe the cabinet occasionally with a dry silica or soft cloth. For heavier dirt, after dampening a soft cloth in a weak solution of mild detergent and water and wringing it out dry, wipe off the dirt. Then, dry immediately with a clean cloth. Do not use rough material, thinners, alcohol or other chemical solvents or cloths since these could damage the finish, remove the panel lettering, or cause discoloration. [. . . ]
