Equalizers
The equalizer is mainly used to correct the frequency range that is overemphasized or
gets lost, no matter it is wide or narrow. In addition, the equalizer can also help us to
narrow or widen the frequency range, or change the amount of a component in the
frequency spectrum. To get it simplified, the equalizer can be used to change the tone of
the signal.
The equalizer has the following control parameters:
- Type: Parametric EQ is a default. High & low shelf filters and high & low pass filters can
be selected. Each kind of filter has different forms to achieve different functions.
- High & Low Pass Filter: The reference frequency of pass-type filter is called cut-off
frequency. Pass-type filter allows the frequencies on one side of the cut-off frequency to
fully pass the filter; in the meantime, the frequencies on another side of the cut-off
frequency are attenuated on a consecutive basis. Among them, high pass filter allows the
frequencies above the cut-off frequency to pass and filter the frequencies below the
cut-off frequency. To the contrary, low pass filter allows the frequencies below the cut-off
frequency to pass and also filter the frequencies above the cut-off frequency.
- High & Low Shelf Filter: It is also called shelf filter. High shelf filter means that the gain
enhances or attenuates for the frequencies above the set frequency. Low shelf filter
means that the gain enhances or attenuates for the frequencies below the set frequency.
The set frequency is not 3dB cut-off frequency but refers to the center of the failing edge
or rising edge of the filter. Q value
affects the peak, and has a mathematical relation with the peak.
- Frequency (Hz): It refers to the center frequency of the filter.
- Gain (dB): It refers to the enhanced or attenuated decibel value of the gain at the center
frequency.
- Q: It refers to the quality factor of a filter. The adjustable range of Q value is 0.02-50;
When the filter is a parametric EQ filter, Q value refers to the width of the bell-shaped
frequency response curve on both sides of the cut-off frequency.
When the filter is a high & low shelf filter or a high & low pass filter, if Q>0.707, there will be
peaks in the filter responses. If Q<0.707, the slope will become flatter, and the roll-off will
occur in advance.
