How to Use a Graphic Equalizer

A graphic equalizer, more commonly known as an EQ is used to change the frequency response, or in other words the tone, of a sound, song, or instrument. It can be used to give more bass, less bass, more treble, etc. Learning to use a graphic equalizer is not too difficult, but it takes a bit of practice to get used to.

    Set all the EQ bands on 0, or in the middle. This will make the audio come out of the speaker without any effects.

    Remember that the left side of the unit, usually starting around 20, is the low or bass side; the right, usually ending at around 16k, is the high or treble side. The mid is between 400 and 1.6k.

  • Typically bass needs to be minimally added or reduced but the treble can ultimately make the audio "cloudy". Once you have your desired amount of bass to your liking, and up to the speaker's capacity then adjust the treble (far right adjustment) then mid area if you still feel the need.
  • Do not over EQ it. The equalizer can compensate for your audio equipment's shortcomings, but remember that professional engineers, with the input of the artist, have balanced the equalization before producing the recording. However, different speakers produce sounds differently, and even the same speakers have a huge variety of frequency response depending on their placement. Thus, one of the main functions of an equalizer is to respond and adjust for a speaker's frequency response.
  • Too many sounds in one frequency can cancel out quieter sounds.
  • EQ is a simple effect, but it can seem hard.
  • You can make the audio sound worse, play around with it.


  • Always adjust the volume, so it won't be too loud!!
