With a 3 band equalizer we break up the spectrum in three sections. the bass for the low sounds; the mid for the mid range; the treble for the high frequenceies ; For each of these 3 bands, we create filters in our circuit to control their respective audible volumes. You can pump up that low frequency bass sound or increase those treble high sounds.

3-octave equalizer should be 5.1. The response of an equalizer stage with these Q values is shown in Figure 7. A filter with a Q of 1.7 (Figure 7) will have a bandwidth that is 1/1.7, or 0.588 of the center frequency. Thus, the 1000-Hz filter with a Q of 1.7 has a bandwidth of 588 Hz. The –3-dB points, therefore, would be logarithmically
