1.Do not increase the output of the amplifier 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 switches or when placing the
stylus on an analog record, set the amplifier volume to its
minimum level.
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.
1 POWER switch
Press to switch the power to the Subwoofer ON/OFF.
2 ON/STANDBY indicator
Lights up according to the operation modes of this unit as de-
scribed below.
Green ................ Power ON (Operating status)
Red .................... Standby mode initiated by remote control
Amber ............... Standby mode initiated by Auto Shut-off func-
tion
Extinguished .... Power OFF or power supply failure
Auto Shut-off.
The Subwoofer automatically returns to STANDBY mode (amber
light) when no signal has been input for about 8 minutes.
When standby is initiated by Auto Shut-off:
The subwoofer returns to the power ON status (operating sta-
tus) in a few seconds when a signal is input or when the power
key of the remote control unit is pressed.
3 Remote control sensor
Receives the transmission from the remote control unit.
4 PEAK INDICATOR indicator
The brightness of this indicator varies according to the amplitude
of the low-frequency component in the input signal.
The PEAK INDICATOR indicator lights very brightly when the built-
in amplifier of the Subwoofer is overdriven.
If the Subwoofer is used in this condition, the sound is distorted
and the Subwoofer itself may also fail. To prevent this, reduce the
volume of the Subwoofer or adjust the amplifier or receiver in
order to reduce the input signal to the Subwoofer.
5 MODE select key
This key selects the sound mode of the Subwoofer. The
Subwoofer incorporates the music and movie modes which can
provide optimum deep-bass reproduction characteristics for the
music source and movie audio respectively. Each press switches
the mode as follows.
6 PHASE select key @
Each press of this key switches the phase of the sound output
from the Subwoofer.
78
Standby mode
While the standby indicator of the unit is lit in red or amber, a small
amount of current is flowing into the unit’s internal circuitry to back up
the memory. This condition is referred to as the standby mode of the
unit. While the unit is in the standby mode, it can be turned ON from
the remote control unit.

- VOLUME CONTROL knob @
Adjusts the volume level of the output of the Subwoofer. Rotat-
ing the knob clockwise increases the volume level, and rotating
the knob counterclockwise decreases the volume level.
= SLOPE selector switch @
This switch selects the attenuation characteristic of the sound
output from the Subwoofer.
~ CROSSOVER control knob @
Turn the control knob to adjust the cutoff frequency of the high-
frequency components in the sound output from the Subwoofer.
