Note: If you are using the Remote Gain, make sure to take this into account during set-up procedures
of the subwoofer amplifier. You should set the system up with the Remote Gain plugged in, and with the
level knob turned all the way down (counter-clockwise).
Crossover Frequency Selection (FREQ)
The built-in low-pass crossover offers continuously adjustable crossover frequencies between 40 and
200Hz. Adjust the setting according to your speaker component specification or to your particular prefer-
ence.
Bass Boost Control (BASS BOOST)
Select a boost level between 0dB and +18dB @ 40Hz to enhance the bass performance for your sound
system. BASS BOOST is NOT free! Every 3dB of boost costs you twice as much in power. Make
sure to set the final gains after setting the Bass Boost to work best with your subwoofer/enclosure
combination. More is NOT always better!
Subsonic Filter (SUB SONIC)
The fixed 30Hz sub sonic filter can be set on/off. When enabled, the integrated sub sonic filter creates
cleaner and tighter bass reproduction by protecting the power amp and speaker from harmful ultra-low
frequencies. We recommend enabling this item at all times.
