This dual concentric control allows the centre frequency to be adjusted between
60Hz to 600Hz by the bottom knob and the cut and boost to be adjusted by ±18dB by
the top knob. The top knob also has a centre detent which disables this section of the
equalizer.

The ‘Q’-control varies the bandwidth of the cut/boost frequency selected as per
6.1.12. As indicated on the front panel when turned towards the low ‘Q’ symbol (‘Q’
approximately 1.0) will cause a wide bandwidth of frequencies to be affected around
the selected center frequency. When set towards the high ‘Q’ symbol (‘Q’ approxi-
mately 3.0) a narrow band of frequencies will be affected around the centre fre-
quency.

This is a variable control for selecting the frequency at which the filter starts to “turn
over” (also known as the knee or -3dB point for the filter). The “turn-over” frequency
is continuously variable between 14 and 400 Hz and provides a cut of 12dB/oct (2nd
