An explanation of what an Equalizer is for absolute beginner mixers.

An equalizer, or EQ, is a powerful tool that allows a mixer to adjust the frequency content of an audio signal. By boosting or cutting specific frequencies within a signal, the mixer can shape the sound of the signal and enhance its impact within the mix.

There are several different types of equalizers, each with its own unique characteristics and capabilities. The most common type is the parametric EQ, which allows the mixer to adjust the level, bandwidth, and center frequency of each individual band. This type of EQ is highly flexible and can be used to make precise adjustments to the frequency content of a signal. This type of EQ commonly has a shelf and filter option as well for further tweaks to your audio.

Another common type of EQ is the graphic EQ, which offers a fixed number of frequency bands that can be adjusted by the mixer. This type of EQ is less flexible than the parametric EQ, but can be useful for making broad adjustments to the frequency content of a signal.

When using an equalizer in a mix, it is important to carefully listen to the sound of the signal and make adjustments as needed to enhance its impact. For example, if a vocal track is sounding dull and muffled, the mixer might boost the higher frequencies in order to bring out the clarity and detail of the vocal. On the other hand, if a bass track is sounding boomy and indistinct, the mixer might cut the lower frequencies in order to make the bass more focused and punchy.

Each instrument in a mix will have its own unique frequency content, and will therefore require different EQ settings in order to sound its best. For example, a guitar might benefit from boosting the upper midrange frequencies in order to bring out its clarity and definition, while a snare drum might benefit from boosting the lower midrange frequencies in order to add punch and body.
