When pressed, power is turned ON; when pressed again, power is turned OFF. 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. Turn the knob slowly from the MIN position. With this unit, the bass level can be independently set, so do not turn up the bass on the stereo amplifier. Used for connecting other equipment through the amplifier. 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. [. . . ] Power supply to amplifier or speaker switch is turned off. The AM loop antenna or the FM indoor antenna is close to this unit. Above specifications are for when power supply is 230 V.
