LMF EQ
The LMF (Low Mid Frequency) equaliser affects the lower middle of the
audible frequency range. The frequency graduations on the sweep con-
trol are the centre frequencies of the EQ. As with the HMF section, the
Q factor is variable from 0.8 to 6. The graph shows the Q setting in the
minimum, and maximum positions, and the extents of the frequency
range.

LF EQ
The LF (Low Frequency) equaliser affects the frequency response of the
lower audible (bass) frequencies. The corner frequency of 60Hz is
around 3dB from the maximum cut or boost of the circuit.
