There are four EQ sections with variable controls for ±18dB cut/boost, frequency,
and Q.
The HF frequency control allows you to sweep through the range 1.5kHz to 15kHz.
MF2 sweeps through 400Hz to 4kHz.
MF1 sweeps through 60Hz to 600Hz.
And the LF frequency control sweeps through the range 20Hz to 200Hz.
The Q control varies the bandwidth of the EQ section in the range Q=1 to Q=3. A low
Q value gives a wide bandwidth. This means that a relatively large range of frequen-
cies (either side of the centre frequency) have the cut/boost applied. A the Q value is
increased, the bandwidth is reduced, so that a very much smaller range of frequen-
cies have cut/boost applied.
