OPERATION
ADJUSTING THE VOLUME BALANCE
Adjust the volume balance between the powered subwoofer and
the left and right speakers of the connected stereo system.
1 Press the POWER button.
The unit enters the power standby mode and the POWER
indicator below the button lights up dimly.
2 Start playback on the connected stereo system.
The unit is automatically turned on and the POWER indicator
becomes brighter when receiving a signal input.
3 Adjust the volume of the powered subwoofer.
Moderate volume setting
To get natural bass sounds, adjust the volume of the powered
subwoofer according to its position and the graphic equalizer
setting of the stereo system.
Adjustment examples
a Set the VOLUME control to a little lower than the middle when
the subwoofer is placed on the floor and the graphic equalizer
is set to off.
b Set the VOLUME control to the middle when the subwoofer is
positioned higher than the floor and the graphic equalizer is
set to off.
• To avoid overloading the powered subwoofer, do not set the
volume of the stereo system so high that the sound is distorted.
• Low frequency sounds may be distorted when they are
emphasized by the graphic equalizer on the stereo system. Adjust
the VOLUME control on the powered subwoofer or the graphic
equalizer on the stereo system.
• If the powered subwoofer will not be used for a long period of
time, press the POWER button to turn off the power, and unplug
the AC cord from the wall outlet.
CHANGING THE PHASE → A
Depending upon the room or the characteristics of the right and
left speakers, sound from the powered subwoofer may seem
unnatural or unusually loud or soft.
In this case, try changing the PHASE switch setting. Set to the
NORMAL or REVERSE position, whichever sounds better.
SETTING THE BASS SOUND RANGE → B
You can adjust the sound range of the powered subwoofer to
complement the sound range of the other speakers.
Set the TURNOVER switch to one of the three positions.

100 Hz: Output 100 Hz and under.
150 Hz: Output 150 Hz and under.
