If no signal is present for more than 9 minutes, the subwoofer automatically reverts to standby mode and the power indicator lights red. If, subsequently, a signal is received, power automatically comes back on and the power indicator lights green. ÷ If you are not using the unit for an extended period of time, please switch off using the power switch, and make sure that the power indicator goes out.
7 Speaker Level Output terminals (SPEAKER LEVEL OUTPUT) When the speakers output terminals on the stereo amplifier are connected to this unit�s SPEAKER LEVEL INPUT terminals 6 and used as the unit�s input signal, these terminals are used to connect the left and right speakers via the unit. 8 Signal ground jack
9 Level knob (LEVEL) Sets the subwoofer volume. ÷ 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. 0 Turnover knob (TURNOVER) Sets the high limit of the frequency played back by the subwoofer. ÷ Setting Criteria 50Hz ......... when the diameter of the left/ right speakers is 20 cm or more. 100Hz ....... when the diameter of the left/ right speakers is 10 � 25 cm. 150Hz ....... when the diameter of the left/ right speakers is 12 cm or less. - Filter through switch (Next to the turnover knob) � There are two settings: � OFF: Use with a regular subwoofer (Possible to set the high frequency limit using the turnover knob) DVD audio bypasses the high frequency filter (a direct audio signal). � Filter through switch: When switched to _ (ON), it will not bypass the filter in the _ ON: connected amplifier. Run the signal directly to the subwoofer for a direct audio signal. = AC power cord Connect to a AC power outlet in the wall.

3 Phase switch (PHASE � 0�/_ 180�) 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. ÷ Normally, the switch is set to (� 0� ). 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. 4 Line Level Output terminal (LINE LEVEL OUTPUT) Used for connecting other equipment through the amplifier. 5 Line Level Input terminal (LINE LEVEL INPUT) Connects to the stereo amplifier�s SUBWOOFER PRE-OUT terminal, with the specially provided RCA plug cord. 6 Speaker Level Input terminals (SPEAKER LEVEL INPUT) Connect to the speakers output terminals on the stereo amplifier, with the specially provided speaker cords.
