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 legend suggests.

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 fre-
quencies 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.
