These frequencies give your mix a sense of power, even when they only occur occasionally. These very low bass frequencies are felt, rather than heard, as with freeway rumbling or an earthquake. To assist you with these adjustments, here is an overview of which frequencies affect different sound characteristics:

For example, the StudioLive Series III mixers offer eight mono 31-band EQs that can be inserted on any mix. Because of this, you’ll generally find graphic EQs as post-fader inserts on modern digital consoles. Instead, make smaller, incremental adjustments over a wider spectrum to round out your final mix. In general, you should not make drastic amplitude adjustments to any particular frequency bands. If you are mixing in a “live” room, you might need to lower the high-midrange and highest frequencies. For instance, if you are mixing in a “dead” room, you may want to boost high frequencies and roll off some of the lows. Graphic EQs are best-used to fine-tune the overall mix for a particular room. In traditional graphic EQ designs, the center frequency of each band is fixed. You will often find this 2/3-octave design on monaural, 15-band (or fewer) graphic EQs in guitar amps, bass amps, and some stompboxes. Graphic EQs with half as many bands per octave are commonly used when less precision is needed.

Professional sound-reinforcement graphic EQs generally have 31 bands, and the center frequency of each band is spaced 1/3 of an octave away from the center frequency of the adjacent bands, so that three bands (three sliders on the front panel) cover a combined bandwidth of one octave. In general, most graphic EQs have between 7 and 31 bands. In general, narrower bandwidth signifies a more precise EQ. Designers of analog EQs must carefully choose the bandwidth of the filter and decide how the bandwidth should vary with gain and how the filters are summed or cascaded. A well-designed graphic EQ creates an output frequency response that corresponds as closely as possible to the curve displayed graphically by the sliders. A graphic EQ typically consists of a bank of slider controls used to boost or cut fixed frequency bands.
