Chapter 3 - Overview
Multiband EQs
2 Band Sweep Shelf EQ, 3 Band Parametric EQ, and 4 Band Parametric EQ
Multiband EQs can be used to flexibly and accurately tailor the tonality of a signal. The 3 band and 4 band parametric EQs in the Q20 can be used to boost and cut multiple bands, with the added flexibility of controlling the bandwidth of one or two mid bands. The multiband EQs provide plenty of equalization in a single Block effect. For instance, the 2 band sweep shelving EQ can be used as a loudness control be boosting both low and high frequencies (Lowpass cutoff frequency set to 150Hz, Highpass cutoff frequency set to 4kHz). The three band parametric can be applied to a mix to simultaneously eliminate hiss, boost bass, and highlight a cowbell. Although it is possible to overlap the different bands, you should be careful to not to be redundant.

5 Band Graphic EQ
A graphic EQ is a set of bandpass filters of fixed frequencies and of equal bandwidths, spaced evenly across the audible frequency range. The 5 Band Graphic EQ in the Q20 has bandwidths that are two octaves wide at 63Hz, 250Hz, 1kHz, 4kHz and 16kHz. Graphic EQs are used for general tonal shaping.
