Maximum cut or boost occurs at the centre frequency set by the
FREQUENCY control.
Q control
Varies the 'Q' (bandwidth) of the cut or boost region. A low Q, CW (clock
wise) affects a wide band of frequencies whilst a high Q, CCW affects a
very small band. The Q control on the MPX10 has a range of 0.3 (3
octaves) to 12 (1/12th octave) - see the following diagram.
In general lower Qs are used when boosting and higher Qs when cutting -
