Set the Switches and Knobs
The following section provides information on how to use the switches
and knobs.
lUse the POWER switch to toggle between OFF and ON/STANDBY.
lOn the TRIGGER/AUTO switch,
oTRIGGER/AUTO set to TRIGGER – the unit will turn ON from
STANDBY when the +12V trigger is detected.
or
oTRIGGER/AUTO set to AUTO – the unit will turn ON from
STANDBY when the signal at the LINE IN connection passes the
signal detection threshold.
lUse the POLARITY switch for applications where the subwoofer is
facing in a direction opposite to the other drivers in the listening
environment.
oPOLARITY set to 0 degrees – the polarity of the incoming input
signal is maintained at the output of the subwoofer.
or
oPOLARITY set to 180 degrees – the polarity of the incoming input
signal is inverted at the output of the subwoofer.
lUse the LFE/CROSSOVER switch to determine whether the
subwoofer’s internal crossover should be included in the signal chain.
oLFE/CROSSOVER set to LFE – the internal crossover is not
included in the signal chain and the input signal must be filtered
using an external Low Pass processor.
oLFE/CROSSOVER set to CROSSOVER – the internal crossover is
included in the signal chain and whatever frequency is selected on
the CROSSOVER knob will be the center frequency for this Low
Pass.
lUse the CROSSOVER knob to select the rolloff frequency of the low-
pass filter for when the LFE/CROSSOVER switch is set to
CROSSOVER.
Test out various values on this knob (in conjunction with the VOLUME
knob) to achieve the optimal low end response for the acoustic
environment on site.
lUse the VOLUME knob to set the output level of the subwoofer.
Power the Unit On

lThe power switch will put the unit into either an ON/STANDBY or an
OFF state.
lIn ON/STANDBY, the subwoofer will change state depending on the
setting of the TRIGGER/AUTO switch.
On the TRIGGER/AUTO switch,
oTRIGGER/AUTO set to TRIGGER – the unit will turn ON from
STANDBY when the +12V trigger is detected.
or
oTRIGGER/AUTO set to AUTO – the unit will turn ON from
STANDBY when the signal at the LINE IN connection passes the
signal detection threshold.
