The upper section of the dual-concentric pot is the ‘boost & cut’ control, giving a vari-
ation of ±18 dB. This control has a centre-detent when in the ‘flat’ position.

The lower section of the dual-concentric pot is the frequency control. The frequency
range is variable from 1.5 kHz to 15kHz.

The MF2 ‘Q’ control varies the bandwidth of the section from Q=1 to Q=3. A low
value of ‘Q’ gives a wide bandwidth. This means that a relatively large range of fre-
quencies (either side of the centre frequency) have the boost or cut applied. As the
‘Q’ value is increased, the bandwidth is reduced so that a very much smaller range of
frequencies have the boost or cut applied.

The LF2 ‘Q’ control varies the bandwidth of the section from Q=1 to Q=3. A low value
of ‘Q’ gives a wide bandwidth. This means that a relatively large range of frequencies
(either side of the centre frequency) have the boost or cut applied. As the ‘Q’ value is
increased, the bandwidth is reduced so that a very much smaller range of frequen-
cies have the boost or cut applied.
