- The number of bands included in a graphic equalizer indicates their suitability and capabilities. Each of these adjustments is called a band. Each band is assigned a specific frequency in a graphic equalizer (or EQ for short), and the number of bands defines the range of frequencies each covers.

What is the difference between a graphic equalizer and a parametric equalizer?
Most graphic equalizers divide sound between 6 and 31 bands of frequency, with a physical or virtual slider controlling the volume of each band. If, for example, the treble is too loud on a track, cutting the volume on one or two of the higher frequency bands can soften it.

Jul 24, 2023 · Graphic EQs typically have anywhere from 5 to 31 bands. The more bands an EQ has, the more precise control an engineer has over the frequency response. How Do Graphic EQs Work? Each slider on a graphic EQ corresponds to a specific frequency band.

Everything you need to know about how a graphic equalizer works and how to get the best setting
A graphic equalizer, more commonly known as an EQ, is used to change the frequency response of selected sounds, such as particular instruments or vocals in an audio track. It can be used to enhance the bass, reduce the treble, highlight a saxophone, or just make your audio sound better overall. EQs can be used in
or live sound. An EQ can be
connected to audio equipment or physical hardware
, or it may be a program on your computer. Once you get a handle on the basic operation of your EQ model, you can use it to make simple audio adjustments, then get into more detailed audio fine-tuning. This wikiHow article teaches you how to use a graphic equalizer.
Graphic equalizers have a series of sliders that control a frequency band within an audible range.
Identify the frequency range and control points for your EQ.
Each of the sliders is called a "band." Each band controls a specific frequency within a range of audible sounds. The 20 hertz (Hz) band controls the low end (bass), while the 20 kilohertz (kHz) controls the high end (treble). Your EQ will most likely have 20 Hz marked on its left side, and 20 kHz marked on the right.
Between the low and high bands, an analog EQ will have a series of vertically-oriented (up-and-down) adjustment sliders. A digital EQ will have a series of marked points spaced out along the horizontal line.
These sliders or control points are often set at 30 Hz, 100 Hz, 1 kHz, 10 kHz, and 20 kHz. Some models allow you to alter these control point settings, while others are permanently fixed at these frequencies.
” upward to intensify a frequency, and “cut” downward to reduce it.
With an analog EQ, pushing a slider upward above the horizontal line “turns up” sounds within that frequency range—this is called boosting. Sliding downward “turns down” the sounds in that frequency range, known as cutting.
Check any EQ presets for the type of audio you’re listening to.
Many stereos, TVs, audio players, and other devices with digital EQ capabilities come with a set of predetermined audio adjustments based on music or audio genre. For instance, your stereo or music app may have presets for “rock,” “jazz,” “classical,” and so on.
By selecting a preset, the various frequency control points will be “boosted” or “cut” to levels that are considered ideal for a particular type of music or audio.
Presets provide a quick way to improve the sound of the audio coming through your headphones, earbuds, or speakers.
Physical EQs don’t usually have presets, since you have to manually adjust the sliders yourself.
Trust your own ears when making EQ adjustments.
Identify the frequency range of common instruments and vocals.
Once you’ve mastered the basics of adjusting the sliders or control points of your EQ, you can make fine adjustments to highlight particular instruments or vocals. With practice, you’ll know where in the frequency range to look for a particular instrument or vocal, but until then, rely on charts like the following:
Female vocals: 150 Hz-1.6 kHz
Male vocals: 60 Hz-500 Hz
Kick drum: 60 Hz-4 kHz
Boost the bar in the chosen range to highlight an instrument.
What do the various frequency bands on a graphic equalizer represent? Each slider on a graphic equalizer corresponds to a specific frequency band: Low frequencies (bass) typically below 200 Hz. Midrange frequencies are in the middle of the spectrum, usually between 200 Hz and 6 kHz.
Nov 12, 2018 · The Klark Teknik DN370 has thirty bands of EQ per channel, each band covering one third of an octave. So this would be called a third-octave graphic equalizer. Each band has a cut or boost up to +/-6 dB (some models offer a wider range up to +/- 12 dB or so).
Graphic EQs typically divide sound into six or 31 bands of frequency, with a slider controlling each band. The number of filters used depends on the EQ. For example, EQs with filters spaced one-third of an octave apart with three filters to an octave would be a one-third octave equalizer.
A graphic EQ typically consists of a bank of slider controls used to boost or cut fixed frequency bands. A well-designed graphic EQ creates an output frequency response that corresponds as closely as possible to the curve displayed graphically by the sliders.
