The boundary frequency between the range being
passed by the filter and the range to be cut is called Cutoff frequency the cut-off frequency. The harmonics of the sound
source signa1s are partiaIly cut by adjuseing the cut-
o_f frequency to influence the tone colorat. ion. Turn-
ing the knob towards H will cause the cut-off fre-
quency to become higher.
