6 Line Level Input terminal (LINE LEVEL INPUT)
Connects to the stereo amplifier's SUBWOOFER PRE-OUT
terminal, with the specially provided RCA plug cord.
7 Line Level Output terminal (LINE LEVEL OUTPUT)
Used for connecting other equipment through the amplifier. The
signal output from this jack is not affected in any way by the
settings of the various controls on the unit.
8 Phase switch (PHASE 0˚
When set to 180˚, the output phase becomes the reverse of
the input signal, and when set to 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.
When using two or more subwoofers together, make sure that
the phase switch of all of them are set to the same position.

Crossover knob (CROSSOVER) & Bypass switch (BYPASS)
When using the subwoofer, set the upper frequency limit for the
subwoofer (50–150Hz) so that it complemets the output from your
other speakers. When using the bass managment features of an
AV receiver, set to BYPASS in order to use the low-pass filter of
the AV receiver for high quality sound.
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.
* When set to BYPASS, the audio signal is routed
directly to the woofer unit, bypassing the
amplifier's filter.
5 Volume knob (VOLUME)
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 or AV amplifier.
