How Does a DJ Mixer Work?

How to Use a DJ Mixer, and How Does It Work?

Before you get into the process of mixing, it is essential to understand the equipment that you will be working on. A DJ mixer is an essential tool that all DJs must own if they want to mix their own music.

A DJ mixer makes use of different audio inputs and merges them together. Apart from merging, the mixer allows you to modify the frequency of the music accordingly.

DJ mixers come in all sorts of shapes and sizes. Here are some of their hardware and key features that you should keep in mind before buying.


A DJ mixer has the following hardware:

  • Input

The input is essentially the sound source that needs to be mixed. Different types of mixers can use different sources for their inputs. For example, some DJ mixers use line-level devices Trusted Source Line level - Wikipedia Line level is the specified strength of an audio signal used to transmit analog sound between audio components such as CD and DVD players, television sets, audio amplifiers, and mixing consoles. as their input source. This can include connection to phones, controllers, and so on.

Other than that, some DJ mixers have their own microphones which allow for a direct source of the sound input. Some mixers are able to connect to computers through digital connections or via USB, in order to gather sound. With different options available, you can literally add any sound possible and use it for mixing.

  • Mixer

Next up, we have the mixer itself. This hardware is at the core of every DJ mixer. It is able to collect all the input and allows you to modify and adjust the sounds. A mixer allows you to change the frequency and volume of each sound. This is where all the magic happens and new music is created.

There can be different types of mixers. From beginner-friendly two-channel mixers to professional and complex six-channel mixers, you can have it all. With the help of a mixer, there are endless possibilities for the music you mix and produce.
  • Output

Lastly, we have the output. An output allows you to listen to your end product after mixing. There are many different outputs that a DJ mixer can have. Some mixers can have booths connected to speakers, while others can have headphone connections. This particular hardware is essential for you to test out your final products.

Key Features

While you can find all sorts of mixers in the market, there are some key features that are common to most DJ mixers:

  • Channel faders are basically volume controls for each audio input. This particular feature allows you to adjust the volume of each audio input accordingly. Each mixer also has a master fader which is responsible for the overall volume of all channels.
  • Cross faders are essential for cutting audio between each input. This is the key feature used for transitioning into a different song.
  • Equalizing knobs allows you to alter the tone for the audio input. With these knobs, you can adjust the frequency for each channel.
  • Each mixer has its own version of an effect section that allows you to add that extra layer to your music while mixing.
  • A filter knob adds further depth to the frequencies of each song. It can help with the transitioning and the build-up of the music.

How to Use a DJ Mixer Properly

How to Use a DJ Mixer, and How Does It Work?

DJ mixing can get complicated at times, but it is the basics that every DJ must master. The following guide will help you on how to use a DJ mixer properly and with the right steps.


Before getting into the mixing process itself, you need to ensure that your mixer is set up properly. To set it up, you have to plug in your output and input it into the mixer. Make sure that each input is connected to the correct channel. For mixers with 1 or 2 channels, you simply have to connect them in a line while ensuring that each plug goes into the correct connector.

If you are using a mixer with 4 channels, then you connect each channel on the correct side. For the mixing process to start, it is absolutely essential that you get this step right.

Apart from the inputs, you also have to ensure that the output is connected correctly and your power lead is in the correct plug. A correct setup also protects your mixer from any electrical damage.

Volume Adjustments

Once you have set up the mixer properly, it is time to adjust the volume of your setup. To fix the overall volume of the output, you make adjustments with the master knob. For the volume of each channel or input, you make adjustments with the channel faders. Before mixing, make sure that all the knobs are adjusted at the 12 o’clock position. You can change that once you have started mixing.

For volume adjustments, make sure that you are using the correct fader for each channel.

As you start playing your music, the volume should be adjusted at a gradual pace. Keep increasing the volume until you have reached your required volume. Ensure you listen to your output to get the correct volume.


After adjusting your volume, it’s time to get acquainted with the controls.

Most 2 channel mixers come with crossfaders as well as channel faders. While the channel faders control the volume for each channel, the crossfaders are responsible for cutting between channel sounds. If you move the crossfader in the middle, it can play both inputs at the same time. And if you want to play either input over the other, you must push the fader to its side. Some mixers have curve adjusting knobs that help you adjust the fade speed.

EQ Meters

Next up, we have EQ adjustments. The EQ setting is usually on the top of every channel fader. Each mixer can have a different number of EQ bands in it. However, these segments help with the trimming and volume adjustments for the sounds. The bands remove any kind of distortion and smooth out the music by helping adjust the frequencies.

VU Meters

While mixing can be technical, it can also be fun with the VU meters. These meters consist of lights that blink with the beat of each tune. You can visualize your sound using these lights. Each color indicates a different sign.

For example, if your lights turn red, then it means that the master volume needs to be adjusted.

Using with Headphones

Mixing can be done efficiently while making use of your headphones. You can hear both tracks simultaneously with headphones, while the main speaker only lets you listen to one. The headphones will let you place both sounds at the same BPM (beats per minute). This lines up the tracks while you start the mixing process.

Each headphone comes with a cue or a mini crossfader. By turning this knob, you can adjust the channel volume you hear in your headphones. You can even equalize the tracks and ensure that sound quality is not compromised while mixing.

Additional Tips

  • While mixing your music, make sure that you adjust the speed of all tracks at a similar pace. Not only this but the volume should also be adjusted properly.
  • If you want to mix different beats, then select some steady inputs that are long enough for crossfading.

As a DJ, you should have active ears and be receptive to how your output is coming out to be.

2-channel vs 4-channel: Is There a Difference in Using Them?

While you may have now figured out how to use a DJ mixer, you must get the proper mixer. While 2-channel mixers are ideal for beginners, 4-channel mixers can be complex and are preferred by professionals. 4-channel mixers basically have the same features as 2-channel mixers, but they come with some additional features, such as:

  • Booth Control

This booth control especially comes in handy when the mixer is being used for big parties and functions. With the help of the booth control, you can connect extra outputs to the mixer and control them with just a single knob. The Pioneer DJ DJM-900NXS2 is a great 4-channel mixer with effective booth control.

  • Effect/FX Panel

4 channel mixers can add an extra layer to the tracks using their effect panels. Commonly known as the FX feature, this helps add echo, delay, reverb, and much more to your track. If you are looking for a mixer with all these features, then you should consider the Traktor Kontrol Z2 DJ Mixer.

  • Microphone

This feature is common to both 2-channel and 4-channel mixers. However, 4-channel mixer microphones come with higher functionality. These microphones allow for high-quality input. The price of the mixer does increase as you get this additional feature.

With a microphone, you can add echo to your track or even customize your own voice by using the EQ functions.

DJ Mixer Software

DJ mixers come with different types of software. Each app/software has its own features and functions:

  1. Traktor Pro is one of the most common software. It is mostly used by DJs who are into mixing hip-hop or EDM music. This software has various features that accommodate the mixing of such genres.
  2. Rekordbox is another common software. This particular software can export music directly from your computer or laptop. However, some outputs may not be compatible with this software.
