[. . . ] Since the sense of direction is lost, the subwoofer can be installed almost anywhere. If it is installed too far away, however, the sound from the left and right speakers may become unnatural. 1 2 3 4 1 2 3 4 5 6 7 Left speaker Right speaker Recommended installation range for the subwoofer Listening position Front left speaker Center speaker Front right speaker Subwoofer Listening area Rear left speaker Rear right speaker To avoid interference with the picture on a nearby TV set, use magnetically shielded speaker systems. This is particularly important for the center speaker since it is usually located closest to the TV. [. . . ] If not enough space is provided between the unit and walls or other equipment, heat will build up inside, interfering with performance or causing malfunctions. For ventilation and to ensure reliable operation of the product and to protect it from overheating, to prevent fire hazard, the openings should never be blocked and covered with items, such as newspapers, table-cloths, curtains, etc. Also do not put the apparatus on the thick carpet, bed, sofa, or fabric having a thick pile. When the surfaces are very dirty, wipe with a soft cloth dipped in some neutral cleanser diluted five or six times with water, and wrung out well, and then wipe again with a dry cloth. Never use thinners, benzine, insecticide sprays and other chemicals on or near this unit, since these will corrode the surfaces. When pressed, power is turned ON; when pressed again, power is turned OFF. With this unit, the bass level can be independently set, so do not turn up the bass on the stereo amplifier. When depressed (_ 180°), the output phase becomes the reverse of the input signal, and when raised (-- 0° ), it is in the same phase as the input signal. But when the sound connection between the subwoofer and the left and right speakers sounds unnatural, try switching to 180° and set the switch in the position where the sound is natural. When the speakers output terminals on the stereo amplifier are connected to this unit's SPEAKER LEVEL INPUT terminals 9 and used as the unit's input signal, these terminals are used to connect the left and right speakers via the unit. Before making or changing the connections, switch off the power switch and disconnect the power cord from the AC outlet. This connection is for a stereo amplifier or receiver equipped with a SUBWOOFER PRE-OUT terminal. If the stereo amplifier or receiver is not equipped with a SUBWOOFER PRE-OUT terminal, carry out a Speaker Level connection. Connect to the LINE LEVEL INPUT terminal on this unit, using the specially provided RCA plug cord. nOTES: ÷ When connected to the PRE-OUT terminal for surround center channel on the stereo amplifier or receiver, the bass is heard only on the center channel, so it will be insufficient. When the power of the stereo amplifier is turned off before the power of this unit is switched off, a shock sound may be generated. In this case, lower the subwoofer volume or turn off the power of this unit. If the stereo amplifier has a switched outlet, connect the power cable of this unit to this outlet. When the subwoofer volume is set to an extremely high level, howling may be caused when the power of the stereo amplifier is turned off or when the speaker switch is turned on. To prevent this, connect the power cable of this unit to the switched outlet of the stereo amplifier. If there is no switched outlet, lower the subwoofer volume or turn off the power of this unit before turning off the power of the stereo amplifier. Also, when using this unit at a high level, do not turn off the speaker switch of the stereo amplifier. [. . . ] 1 No power is being supplied (Indicator does not light up when power switch is turned on. Turn the amplifier's output level (volume, bass control, bass boost) counter-clockwise to lower the level. Increase the distance between the AM or FM antenna (for indoor use) and this unit.
