How to Connect Laptop to Mixer for Sound Step by Step Guide

Often you need to attach a laptop or another media device such as a tablet, iPad, or mp3 player to your music mixer. This setting’s style is prevalent for karaoke settings where DJs attach their Laptop to the mixing board for a live show with their playlist and DJ apps.

This post describes a few simple and straightforward ways to connect a laptop to a sound mixer. If you have to connect your machine to a recording mixer, read this post on How to Connect Laptop to Mixer for Sound.

What Is A Digital Mixer

Let’s remember, for a little context, what the digital mixer can do and how. An electronic system for integrating the sounds of several different audio signals is a wireless mixing console. 

These involve vocal and acoustic music microphones, electric instruments, and captured music signals. They change the signals to create a composite output signal ready to be transmitted, amplified, or charged using a sound strengthening method.

There can be up to 90 channels on a mixer in a professional recording studio. Mixers do more in practice than merely combine sounds. They can provide condenser microphone phantom control, filtering and equalization, and dynamic compression range.

This last one helps sound specialists without stressing the machine to improve the overall benefit. They can also send the signal from the mixer to another unit, such as a recording system or a monitoring room, and control installations that allow various sources to be routed to speakers and listening headphones. 

It is achieved without impacting the mixture’s actual production. Some mixers have an integrated reverb and can have a power amplifier.

Getting to know your Mixer’s Input Channels

As you should know, there are several knobs and many input channels in the mixing consoles. If you don’t remember a mixing board, it can be very daunting to look at it because every knob has its purpose, and you don’t know where to start.

It would help if you had a stereo channel to connect a laptop to a mixer. The explanation is that your machine’s audio is a stereo signal, which means left and right channels. Most mixers with their EQ knobs have stereo input channels to align the sound with your wishes.

They usually have two numbers. You can see, for example, a single channel labeled 9/10, 11/12, etc. Both numbers indicate two channels or a stereo.

The picture below shows the available stereo input channels you have to look for when attaching your Laptop to a playback mixer. I’ve included some different audio mixer brands to give you a better comparison.

When you look at the picture below, the channels with two numbers with left (L) and right (R) inputs have 1/4′′ phone jack connections. These connectors can be used to connect to your mixer, your Laptop, or your mobile device. Some mixers still use RCA types, but 1/4′′ phone jackets are the most common.

Equipment Needs To Connect A Digital Mixer To A Computer?

It would help if you had an audio interface to get the audio from your wireless mixer to your computer. These are also known as soundcards. You could have an onboard soundcard on your machine & it may also have mini-jack connections with a line or microphone inputs. If so, you can insert the digital mixer’s output into the input of your onboard soundcard, be it out, show, recall, or aux sound.

You will need a cable with the corresponding ends. You would also need two mono-1/4-inch jackets at one end of the cable and a stereo mini-jack at the other end when connecting from the 1⁄4-inch jack to a mini-jack line input of the machine soundcard. It enables almost every recording kit to listen to the incoming audio.

Alternatively, you can buy an external audio interface that fits your particular requirements. Any of these are on the market, and they are not costly.

How to Connect Laptop to Mixer for Sound Using a Cable

We use the 3.5 mm female jack connector headphone output to connect the Laptop, iPad, tablet, or mp3 player to the mixing board. All you need is a stereo connector of 3.5 mm to two 1/4″ male jack connectors (link to Amazon). For your reference, I have included the picture below.

Follow these steps to attach your Laptop to a music mixer:

  • Make sure the volume slider for the mixer is down to the channel you are going to use.
  • Attach the 1/4′′ left (White) jack to the blender.
  • Attach the 1/4″ right back to the mixer.
  • Make sure no audio playback is possible until attaching the 3.5mm stereo jack to a laptop.
  • Attach the 3.5 mm laptop stereo port.
  • Play some music on your Laptop and steadily raise the slider volume on the mixer until you hear the sound coming from the speakers.
  • Use EQ buttons to change the heights and lows to suit your tastes.

How to connect a digital mixer to your computer

To attach a mixer to the line input on your machine, you will need a dual RCA to a mini-plug (1/8 inch). Then plug the RCA plug into the RCA output jackets behind the mixer. Then insert the mini stereo plug into your computer’s input port.

If you do not have an input line port on your computer that does not include many Windows laptops, you will need a USB audio interface on a line level and a cable that connects the mixer’s output port with the USB interface input port. Then the USB interface connects to the laptop USB port.

Other Way of Connecting a Laptop to Your Mixer

The other way to connect your Laptop computer to a mixer is by using two mono-channels, one on the left and the other on the right. Some older analog mixing consoles do not have a single stereo signal communication channel. If so, then two different mono channels must be used.

Let’s say we’ll use channels 1 and 2. The first thing is to find the “PAN” button, usually over the volume slider.

After it has been found, switch the channel 1 “PAN” button to the left and channel 2 PAN button to the right. You set every single channel to one side of the stereo bus.

Link the left(white) jack to channel 1’s input marked “LINE,” and the right (Red) jack to channel 2’s input labeled “LINE.”

I advise you to set the EQ and volume sliders up to the same level, so both channels have the same volume.

How to test your input connection:

Use the sound control panel or the custom mixer for your particular soundcard, pick the input device you want to attach, and then search for sound from the mixer. The sound control panel of your machine takes you through a comprehensive step-by-step procedure for this program.

    To connect a sound mixer to your Windows laptop input line, you need to purchase a double facing RCA with a 1/8″ tiny plug cable. Now, the RCA terminals must be connected to the RCA terminals at the back of the sound mixer.


An electronic system for integrating sounds from several different audio signals is a wireless mixing console. These involve singer and acoustic instrument microphones, electric instrument signals, and recorded music.
