When the Cross-Over Filter switch is set to LPF (Low Pass Filter) the adjustable frequency range
is 40Hz-400Hz.
When in the minimum position (turned fully counter-clockwise) all frequencies less than 40Hz
will be filtered from the output signal and all frequencies above 40Hz will be heard from the
speakers.
When in the maximum position (turned fully clockwise) all frequencies less than 400Hz will be
filtered from the output signal and all frequencies above 400Hz will be heard from the speakers.
The volume will be lower when the frequency is getting close to the minimum position.
3.3.2 Low Pass Filter Mode
When the Cross-Over Filter switch is set to FULL no frequencies will be filtered and the speakers
will output all frequencies.
3.3.3 Full Range Mode
The Boost setting allows for additional Bass Boost to be added to the output signal. The boost is
applied to 85Hz frequency and allows for 0-12dB of boost.

will be filtered from the output signal and all frequencies above 40Hz will be heard from the
speakers.
When in the maximum position (turned fully clockwise) all frequencies less than 400Hz will be
filtered from the output signal and all frequencies above 400Hz will be heard from the speakers.
The volume will be lower when the frequency is getting close to the minimum position.
