HF EQ
The HF (High Frequency) equaliser affects the frequency re-
sponse of the higher audible frequencies. The corner fre-
quency 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 frequencies of the EQ. The
range has been carefully chosen to cover "boomy" frequen-
cies around 120Hz to 250Hz which may need cutting back, or
a lift at 2 to 3kHz 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.
