zLine input connector (LINE IN)

•Connect this to the AV amplifier’s pre-out connector (“SUBWOOFER”, “MONO OUT”, etc.) using the included connection cord (3-meter RCA pin cord).

xLine output connector (LINE OUT)

•The signal input to the line input connector is output as such from here in parallel.

•When using two active subwoofers, connect the other active subwoofer’s line input connector to this connector.

cPhase selector switch (PHASE)

•This switches the phase of the output signal with respect to the input signal.

•Normally use the subwoofer with this switch set at the “NORM.” position. If the continuity between the sound of the active subwoofer and the left and right speakers seems unnatural, try switching to the “REV.” position, and set the switch to the position in which the sound is most natural.

vLF direct switch (LF DIRECT)

•When using the active subwoofer connected to a Dolby Digital- or dts-compatible AV amplifier, if this function is turned on the signals bypass the active subwoofer’s crossover and volume adjustment circuits, resulting in purer, higher quality

sound. Note that when this is done the crossover adjustment control (b) and volume adjustment control (n) will no longer function.

bCrossover adjustment control (CROSSOVER)

•This control only functions when the LF DIRECT switch (v) is set to the “OFF” position.

•This control sets the upper limit of the frequencies reproduced by the active subwoofer.

•Setting criteria

50Hz : For left/right speakers with diameters of 20 cm or greater

100Hz : For left/right speakers with diameters between 10 and 25 cm

200Hz : For left/right speakers with diameters of 12 cm or less

•When using a Dolby Digital- or dts-compatible AV amplifier, we recommend turning the LF DIRECT switch (v) to the “ON” position and not using this function.

About the AV amplifier’s crossover frequency selection

The crossover frequency of the satellite speaker/center speaker and the active subwoofer (the boundary between the frequency range produced by the active subwoofer and the other speakers) is set on the connected AV amplifier, and is usually fixed at between 80 and 120 kHz.

With some amplifiers, however, including the Denon ADV- M51, this frequency can be selected. When using this type of amplifier, the crossover frequency can be selected to suit your tastes.

When using the DSW-3L active subwoofer with this type of amplifier, a richer sound can be achieved by setting the crossover frequency to around 150 Hz. Adjust the crossover frequency to suit your tastes. For instructions on switching, refer to your amplifier’s operating instructions.

When connecting to a Dolby Digital- or dts-compatible AV amplifier, whether one on which the crossover frequency is fixed or one on which it can be adjusted, we recommend setting the LF DIRECT switch of the active subwoofer (DSW- 3L) to the “ON” position.

nVolume adjustment control (LEVEL)

•This control only functions when the LF DIRECT switch (v) is set to the “OFF” position.

•Use this control to adjust the volume of the active subwoofer.

•When turned clockwise ( ) from the center position, the volume of the active subwoofer increases, and when turned counterclockwise ( ), the volume decreases. Set to the desired position.

mAuto standby selector switch (AUTO STANDBY)

ON	: The auto standby function is activated
OFF	: The auto standby function is deactivated

Auto Standby Function

•The amplifier is automatically set to the standby mode if no signal is input for 5 to 11 minutes, thereby saving electricity.

The power turns on immediately when a signal is input.

,Status indicator

•The two-colored LED indicates the active subwoofer’s operating status, as follows:

Power “ON”	Lights green
Auto power off (standby mode)	Lights red
Power “OFF”	LED off
Protective circuit activated	Flashing red

.Power switch (POWER)

•The power turns on when this switch is set to the “ON” position.

•Several seconds are required for the set to begin operating. This is because the set includes a built-in muting circuit to prevent noise when the power switch is turned on and off.

•When set to the “OFF” position, the power turns off.
