MF EQ
The MF (Mid Frequency) equaliser affects the middle of the audible
frequency range. The frequency graduations on the sweep control
are the centre frequencies of the EQ. The range has been carefully
chosen to cover “boomy” frequencies around 120Hz to 250Hz
which may need cutting back, or a lift at 2 to 3kHz may be required
for microphone intelligibility.
LF EQ
The LF (Low Frequency) equaliser
affects the response at the low end of
the audio range. The graph shows the
response of the LF EQ at maximum
cut and boost. The corner frequency
is 80Hz.
HF EQ
The HF (High Frequency) equaliser affects the frequency response
of the higher audible frequencies. The corner frequency of 12kHz is
around 3dB from the maximum cut or boost of the circuit. It has
plenty of gain and actually gives slightly more that the +/-15dB leg-
end suggests.
