PRECAUTIONS Read these precautions carefully before using your speaker. . Any time you note distortion, reduce the volume control on your amplifier to a lower setting. Never allow your amplifier to be driven into “clipping”. Otherwise the speaker may be damaged. . When using an amplifier with a rated output power higher than the nominal input power of the speaker, care should be taken never to exceed the speaker’s maximum input. . Do not attempt to clean the speaker with chemical solvents as this might damage the finish. To clean, wipe with a dry, soft cloth. . To prevent the enclosure from warping or discoloring, do not place the speaker where it will be exposed to direct sunlight or excessive humidity. . Do not place the speaker where it is liable to be knocked over or struck by falling objects. Stable placement will also ensure better sound performance. . Secure placement or installation is the owner’s responsibility. YAMAHA shall not be liable for any accident caused by improper placement or installation of the speaker. PLACING THE SPEAKER The rear center speaker should be placed behind the listening position, and equidistant from the two surround speakers. The positioning of the rear center speaker is important, because it controls the whole sound quality of a multi channel system. REMOVING THE FRONT COVER The front cover is fastened to the enclosure at four points, and can be removed if desired. To remove the cover, hold on to both sides and slowly pull straight away from the speaker. To reattach, line up the four pegs on the inside surface of the cover with the four 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.

CONNECTIONS TO YOUR AMPLIFIER CONNECTIONS TO YOUR AMPLIFIER This speaker system is capable of standard connections and bi-wiring connections. Before making connections, make sure that the amplifier is switched off. – CENTER + REAR Leave the short bars in place when connecting. Short bar – + Rear center speaker Amplifier or Receiver – CENTER REAR Woofer terminals Rear center speaker Amplifier or Receiver Loosen Tighten Tweeter terminals + – ¦ Connections . Connect the screw-type input terminals at the rear of the speaker to the speaker output terminals of your amplifier with the speaker cables. . Connect the (+) terminals on both the amplifier and the speaker using one side of the cable. Connect the (–) terminals on both components using the other side of the cable. . Connect the speaker to the rear center terminals of your amplifier, making sure not to reverse the polarity (+, –). If this 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 connections 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. Bi-Wiring Connections This speaker system is capable of bi-wiring connections. To connect the speaker 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...
