Woofer terminals Tweeter terminals n Connections . Connect the screw-type input terminals at the rear of the speakers to the speaker output terminals of your amplifier with the speaker cables. . Connect the (+) terminals on both the amplifier and the speakers using one side of the cable. Connect the (–) terminals on both components using the other side of the cable. . Connect one speaker to the left (marked L) terminals of your amplifier, and another speaker to the right (marked R) terminals, making sure not to reverse the polarity (+, –). If one speaker is connected with reversed polarity, the sound will be unnatural and lack bass. Procedure: . Loosen the terminal knob. . Remove approx. 10 mm (3/8”) insulation from the speaker cable and insert the bare wire end properly into the terminal hole. . Tighten the knob. . Test the security of the connection by tugging lightly on the cable at the terminal. Note Do not let the bare speaker wires touch each other as this could damage the speaker and/or the amplifier. Both SPEAKERS A and B should be selected. Bi-Wiring Connections This speaker system is capable of bi-wiring connections. To connect the speakers to the output terminals of the amplifier, two pairs of cables for each of woofer and tweeter are used instead of standard connections. This type of connection decreases the modulation distortion caused by electric resistance of the cables and driving current of the speakers. Consequently, purer sound quality can be expected. To utilize bi-wiring connections, remove the short bars from the terminals first, and then connect the woofer and tweeter to the amplifier separately using two pairs of cables. Note For bi-wiring connections, use the same type of cable for both the woofer and tweeter, making sure to match the polarity. PLACING THE SPEAKERS n Using as 2ch stereo speakers Better stereo images will be obtained when the speakers are slightly angled in towards the listeners. n Using as main speakers in a multi channel system Position the speakers on both sides of the TV. The positioning of speakers is important, because it controls the whole sound quality of a multi channel system. Set up the speakers on the basis of your listening position by following the owner’s manual supplied with your amplifier.

To remove the cover, hold on to both sides and slowly pull straight away from the speaker. To reattach, line up the six pegs on the inside surface of the cover with the six corresponding holes on the speaker and push gently. Note When the cover is removed, take care not to touch the speaker units with your hands or to exert excessive force with tools.
