Bass and Treble Shelving
Bass and treble shelving can be added to the filter. Also known as shelving or tone
controls, the separate bass and treble filters provide the ability to cut or boost gain
linearly above or below a selected frequency, with the end-band shape giving the visual
appearance of a shelf.
Adding the filter automatically inserts both a bass and a treble control row. If only a bass
or only a treble filter is required, either bypass the unneeded control or set it to
Unused in
the selection box (see row 3, row 4, and row 5 in figure 28).
Figure 28. Bass and Treble Shelving
The corner frequency of the controls can be selected to 0.1 Hz accuracy. Two slopes,
6 and 12 dB/octave are selectable along with the ability to boost or cut the signal up
to 24 dB.
