• Knob A: Frequency, <<out, 20.0Hz to 25.6kHz, out>>
• Knob B: high pass filter type
Filter type is selectable from Butterworth, Bessel, Linkwitz-Riley and Hardman. Filter slopes
of up to 8th order or 48dB / octave are provided. Not all filter types are available in all
slopes. For example 18dB / octave Linkwitz-Riley filters do not exist.
The Hardman type filter is always described by its’ order as the filter becomes progressively
steeper rather than following a linear slope so a dB/octave description is not accurate.
