Low Pass - High Pass Filters
The low pass and high pass filters available in the AVP offer both a 6dB
per octave and a 12dB per octave roll-off characteristic. The 6dB per
octave versions offer a more subtle effect, while the 12dB per octave
roll-off is useful for attenuating sub-sonic noise, rumble, mic stand noise,
high frequency hiss, and other environmental noises encountered in the
recording process. Additionally, the 12dB per octave versions provide a
“Q” control that allows you to create a variable height peak at the cut-off
frequency.
