Each band of the equalizer consists of 3 controls. Two controls are combined on a
dual concentric control. The top knob controls the Cut and Boost and the bottom
knob controls the centre frequency. The third control of each section varies the ‘Q’
factor.

This dual concentric control allows the centre frequency to be adjusted between
1K5Hz to 15 KHz 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 dual concentric control allows the centre frequency to be adjusted between
400Hz to 4KHz by the bottom knob and the cut and boost to be adjusted by ±18dB

the equalizer.
