Example of standard adjustment according to the type of
front speakers.
Depending on the listening room condition and the front
speaker characteristics, other adjustment setting than the ex-
amples shown above may provide more natual bass sound and
more effective bass reproduction. Try various adjustment set-
tings to select the optimum one for your listening room.

Controls and indicators
1 Power on / standby indicator
This indicator indicates operation mode when it lights in green,
and the Standby mode when it lights in red.
2 POWER switch
Switches the power ON and OFF.
3 VOLUME control knob
Adjusts the volume level of the output of the Subwoofer. Ro-
tating the knob clockwise increases the volume level, and ro-
tating the knob counterclockwise decreases the volume level.
4 TURNOVER switch
Set this switch (to ON or OFF) according to the output signal
from the amplifier or receiver which is to be connected with
the Subwoofer.
ON: To help the Subwoofer manifest its performance most ef-
fectively with an ordinary subwoofer pre-out signal or line-level
signal, this position cuts the other components than the low
frequency component so that only the bass sound is repro-
duced through the Subwoofer.
OFF: The subwoofer output signals from these amplifier or
receiver are customized to cut other components than the
required low frequency component in an optimum manner
according to the current sound mode in use. When the
Subwoofer is combined with one of these amplifier or receiv-
er, the TURNOVER switch should be set to OFF: The Subwoofer
does not apply electrical filtering to the input signal and repro-
duces it faithfully through the loudspeaker.
TURNOVER function does not work when the TURNOVER
switch is OFF.
5 TURNOVER control knob
Ajusts the balance between the bass from the front speakers
and the bass from the Subwoofer.
Caution concerning operation
An excessive input level to the Subwoofer may impair the sound
quality or damage the unit. Careful attention should therefore
be paid to the following precautions.
Notes:
1. Do not increase the output of the amplifier or receiver to a
high level while the low-frequency level is enhanced by
the amplifier’s tone control or loudness control.
2. When operating the amplifier or receiver switches or when
placing the stylus on an analog record, set the amplifier or
receiver volume to its minimum level.
