band above 15 dB, the filter gets very aggressive and reso-
nant. You can use this feature to good effect when you need
to reconstruct a resonance for a recorded instrument that
lacks one. For example, you could place a narrow +24 dB
peaking filter between 60 and 80 Hz on a kick drum track
that lacked a “belly” for the drum.
F ILTER BAND FREQUENCY
Use this knob (labeled “Hz” in the illustration) to adjust the
characteristic frequency of the filter. For the peaking and
bandpass filter types this controls the center frequency of the
filter. For the high and low cut filter types this control adjusts
the 3 dB point of the filter. For the shelving filters this control
adjusts the shelf transition point.
F ILTER BANDWIDTH
Use this knob (labeled “BW” in the illustration) to adjust the
characteristic width of the filter. This control only has effect
for peaking, shelving and bandpass filter types. Please note
that this parameter controls the bandwidth (measured in
octaves), not the quality factor (or “Q”). If you have been
using Q controls, the numbers will be backwards from what
you are used to. Small numbers mean narrow filters and
large numbers mean wide filters. For peaking and bandpass
filter types, this parameter controls the bandwidth of the fil-
ter in octaves. For the high and low shelving filter types this
parameter adjusts the amount of dip/peak and the slope of
the shelf. When this parameter is set to 0.1 you will get the
largest dip/slope available and when the parameter is 2.5,
you will get a classic first order shelf (which has a transition
band that is about 1 decade wide; e.g. if it is a high shelf
