AC IN connector
Connect the supplied power cable here. First connect the
power cord to the subwoofer, then insert the power cord
plug into the AC outlet.
INPUT L/R connector
These connectors receive the input signal to the
subwoofer. Balanced XLR and balanced phone jack

connectors are output via the OUTPUT L and R
connectors, respectively. Low frequency reproduction
characteristics can be adjusted via the LOW CUT
switch and LOW CUT control.
LOW CUT switch
When this switch is ON, the low frequencies are
attenuated prior to output via the OUTPUT L and R
connectors at the frequency set by the LOW CUT
control. The low-frequency attenuation cutoff
frequency can be adjusted via the LOW CUT control.
LOW CUT control
Adjusts the low-frequency attenuation cutoff
frequency between 80 Hz and 120 Hz when the LOW
CUT switch is ON.
HIGH CUT control
Sets the cutoff frequency for subwoofer output high-
