Amplifier Adjustments: High and Low Cutoff Filters
The Low Filter Cutoff is designed to significantly reduce (12 dB per octave roll off) the
extremely low frequencies, those below 25 Hz. This is the subsonic range, below the
frequencies that we can hear with our ears. In movies and games, this is usually where
large explosions will shake you. However, often in music, this is a dead zone mostly
filled with noise. Switching the Low Filter Cutoff switch on will lower the intensity of
these low frequency vibrations.
The High Cutoff Filter is designed to reduce and eliminate the frequencies in the upper
range of the ButtKicker Gamers response. This can be used to put a ceiling on the
frequency response of the ButtKicker Gamer to help eliminate unwanted buzzing and
the occasional human voice that may be transferred in the upper frequency range of
the ButtKicker Gamer. To eliminate unwanted effects, turn on the High Cutoff Filter
and starting from the highest frequency, turn the High Cutoff Frequency knob down
until you achieve the desired effect. When active, lowering the High Cutoff Frequency
can also help to reduce the response to in-game music without significantly reducing
the low end effects.
