Central Frequency (Fc):
The central frequency of each filter setting.
Gain:
The gain for the central frequency.
Quality Factor:
The range of effect of the filter.
As shown on the pictures below, the larger value of the
Q factor, the smaller the effect compared the central
frequency. The smaller value of the Q factor, the larger
the effect in relation to the central frequency.
The following are the curves of the filters
(Fc=100Hz, gain=4dB)
Parametric Equalizer Setting Instruction:
