[. . . ] 14 English SETTING UP THE SPEAKERS Before making connections, place all speakers in their respective positions. The positioning of the speakers is important because it controls the whole sound quality of this system. Place the speakers depending on your listening position by following the instructions below. Speaker configuration This speaker package employs a 7 speaker configuration: 2 main speakers, 2 rear speakers, a center speaker, a rear center speaker and a subwoofer. The rear and rear center speakers are used for surround sounds, and the center speaker is for center sounds (dialog etc. ). The subwoofer is for reinforcing low frequencies on your audio system. Placing speakers Main speakers: Rear speakers: On both sides of and at approximately the same height as the TV set. Precisely between the main speakers. Center speaker: Rear center speaker: Precisely between the rear speakers. Subwoofer: The position of the subwoofer is not so critical because low bass tones are not highly directional. Refer to "Placing the subwoofer" below for a recommended positioning of the subwoofer. Main L Center Main R Subwoofer Subwoofer Main R Center Main L TV-set Rear R Rear L Rear center Rear R Rear center Rear L Placing the subwoofer Å i It is recommended to place the subwoofer on the outside of either the right or the left main speaker. i is also possible, however, if the subwoofer system is placed directly facing the wall, the bass effect may die because the sound from it and the sound reflected by the wall may cancel out each other. To prevent this from happening, face the subwoofer system at an angle as shown in fig. Note There may be a case that you cannot obtain enough superbass sounds from the subwoofer when listening in the center of the room. * Connect each speaker making sure not to reverse the polarity (+, ­). If the speaker is connected with reversed polarity, the sound will be unnatural and lack bass. * For the main and rear speakers only, connect one speaker to the left (marked L) terminals of your amplifier, and another speaker to the right (marked R) terminals. Note When connecting to a monaural line output terminal of the amplifier, connect to the L/MONO INPUT2 terminal.
