 Index to speaker parts Notes on usage  Do not touch the diaphragm of each speaker unit.  The color and appearance (grain patterns) may vary among the enclosures because natural wood is used. Depending on lighting conditions, the enclosures may look different, but this does not indicate damage.  Do not put any object or your hand into either of the ducts located on the rear of the enclosure.  If there is a foreign object in the duct, do not attempt to take it out by yourself. Please consult your nearest dealer. *1 Before attaching the grille frame, confirm its correct mounting orientation. When attaching, press above the pin to firmly secure it. If the grille frame is protruding outward (it will not come off), push it all the way in. Attaching the grille frame is recommended even when not using the speaker in order to protect them from damage. The speaker can be enjoyed with the grille frame attached, but superior performance can be achieved by removing the grille frame. When removing the grille frame, take care not to bend or distort its shape excessively.  Setting the speaker Speaker placement is one of the most important factors in obtaining high-quality sound. Observe the following when placing your speaker to obtain full advantage of the speaker characteristics:  Set up the speaker on a hard, flat place.  Setting the speaker on the rack is recommended Depending on the rack type, you can set the speaker into the rack (-). Do not place the speaker in the following locations:  In places subject to high temperature or direct sunlight  In places subject to excessive dust and dirt  In places subject to high humidity  Near source components (CD players, record players, etc.)  Near magnetic cards (credit cards, commuter passes, etc.) Magnetic cards may fail due to the magnets in the speaker units.  Nearby devices that can be influenced by magnetism, such as a digital video recorder. Place those devices more than 5 cm (2 in) away.  Near televisions The speaker is not magnetically shielded. Therefore, if you use the speaker near CRTbased televisions, color shading occurs on the television screen. If color shading occurs, turn off the television, then turn it on again after 15 or 30 minutes. If the color shading persists, increase the distance between the speaker and television.  AV receiver connections Selecting the receiver/speaker cords Select a receiver (not supplied) and speaker cords (not supplied) meeting the following requirements. For selecting a receiver: The speaker impedance is designed as 4 ohms. Excessive sound volume may damage the speaker, so be aware of the position of the volume level knob on the receiver and avoid excessive input. Requirement for selecting speaker cords In order to output high-quality sound signals, use speaker cords of the minimum necessary length that are treated with either of the following two fittings at their ends:  With cable cores (less than 4.5 mm (3/16 in) in diameter) bared by stripping the jacket to 10 mm (13/32 in) from each + and - end The bare cable core may become oxidized over time. In this case, reconnect the speaker cords after stripping the jacket to expose a fresh segment of cable core at each end. This will ensure that you can enjoy better sound.  With spade plugs (more than 8 mm (11/32 in) in inner diameter, and less than 12 mm (1/2 in) in outer diameter) Connecting to the receiver Before connecting, turn off the receiver. Connect the terminals of the speaker to the center speaker of the receiver. Note Tighten each binding post securely. Periodically checking the tightness of the binding posts is recommended to prevent them from becoming loose as time passes. About aging The speaker takes some time to provide their best performance. Play the speaker at normal volume for about 10 hours to break them in.

Precautions Before turning a receiver or a source component on/off Set the volume of the receiver to minimum. If the bass cannot be heard or the phonic positions of instruments are indefinite Make sure to connect the speaker cords by matching +/- to the appropriate speaker terminals. Cleaning of the enclosure  Do not use any type of neutral detergent, benzene, or alcohol because they may damage the surface finish of the enclosure.  To maintain the fine gloss of the enclosure for a long time, gently wipe off dust using a soft brush or feather duster, and then wipe the enclosure with the supplied cleaning cloth. (Do not use any type of scrub brush or sponge.)  Wipe smudges such as fingerprints or oil spots with the supplied cleaning cloth carefully.  When the smudges are hard to remove, wipe them off with a soft cloth soaked in soapy water, and wrung dry.  Make sure not to damage the enclosure.  The supplied cleaning cloth is washable and can be used repeatedly. To avoid damaging the speaker  Do not disassemble or modify the speaker units, network circuits, or the enclosure.  If sound is distorted or noise occurs, amplifier power output may be overloading the speaker units. Turn down the volume, or the speaker units may be damaged. To avoid damaging the circuits Do not input the following signals continuously:  FM inter-station noise  High-frequency signals of electronic instruments  High output and high-frequency signals in the fast-forward and rewind modes of a tape recorder
