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 which may be required for microphone intelligibil-
ity.
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 re-
sponse of the higher audible frequencies. The corner frequency
of 12kHz is around 3dB from the maximum cut or boost of the
circuit and has plenty of gain.
