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 AVR-770SD and ADV-M71, 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.

Volume 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 (

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.
