How to Connect a Mixer to an Amplifier: Easy Steps Just for You 

With the right equipment, we can create different sounds and frequencies, which is how songs and beats are created. The mixer is one key component in sound production and is used in various places.

Other equipment, such as the amplifier, can be used in connection with the mixer for a better sound experience. You can connect the mixer to the amplifier using the connection cables.

This article will show you all you need to know about the amplifier and mixer and how to connect a mixer to an amplifier. Furthermore, we’ll show you other forms of connection for better sound quality.

Before we look at how to connect a mixer to an amplifier, let’s try to understand them and see what they’re about.

What is an Amplifier?

An amplifier is a device used to strengthen and transmit audio signals. As the name suggests, the amplifier amplifies weak frequencies and transmits them as higher signals to produce louder notes.

An amplifier consists of different units, the input signal source, the internal components, and the output unit. All these components work together to receive signals, amplify the signals, and send the signals to speakers or woofers.

Different types of amplifiers are based on their internal components: voltage amplifier, transconductance amplifier, instrument amplifiers, etc.

What is a Mixer?

Audio sound mixer and amplifier equipment

A mixer is an audio tool that adjusts audio frequencies to derive a range of sounds. There are different mixers: digital mixers, analog mixers, and powered mixers.

Thedigital mixers operate with digital signal processing technology and can operate with various tones, volumes, and audio signals. Digital mixers are very versatile and also reliable for handling multiple audio inputs.

Analog mixers are not as developed as their digital counterparts and are limited in their range of operation. Analog mixers operate with input audio signals, making them easier to operate.

Powered mixers are a lot like analog mixers: the difference is the presence of powered amplifiers. The powered mixers come with powered amplifiers, ready to connect with your speaker immediately.

Amplifiers are added to the mixer to generate strong signals that the speakers or microphone can interpret. Audio mixers have a lot of applications since they can merge multiple audio signals to produce new variations.

Unlike powered mixers with an amplifier, it can be difficult for the other forms to produce powerful signals for the microphone.

Let’s look at how to connect a mixer to an amplifier.

With these easy steps, you should be able to connect your mixer and amplifier without any stress.

Ensure Safety

Before making any connections, you first need to ensure that it’s safe to do so. You will be dealing with electrical appliances, and we know current flows once there is a connection. To ensure safety, ensure that you turn off all power sources.

Disconnect the mixer and amplifier from their power source, and only turn them on after you’re done with the connection.

Also, set up your speakers and avoid piling up cables around the speakers.

Get the Right Connector Cables

You will need a connector cable to link your mixer with your amplifier. The connector cables are the main equipment for connecting the amplifier and the mixer, and you need compatible cables.

We mentioned that there are different types of mixers and amplifiers and different types of output and input. You need to check the outputs of your mixer and the amplifier’s input to determine what type of connectors you’ll need.

Asides from the compatibility of the connector cable, you also need to consider the length. You should get a cable that will conveniently cover the distance between your mixer and amplifier. The last thing you want is to strain your connection cable as it can cause clipping in your sound.

If you’re having problems identifying the type of cables you need, you can check the manual that comes with the mixer and amplifier.

Connect the Cable to the Mixer

After getting the right cable combination, connect one end to the mixer – a panel at the back contains different output jacks.

Remember to turn off both the mixer and amplifier before attempting this part. At the back of the mixer are two jacks, right and left. Connect the left connector cable to the left jack, and the right connects the cable to the right output jack.

Connect the Connector to the Amplifier

After connecting to the mixer, take the other end of the RCA plugs and fit them into their respective colors on the amplifier. Note that if you get the color combination wrong, you will not get the desired sound effect.

Verify the Connection

The next step is verifying your connection. Turn on your entire setup. The mixer should transmit sound to the amp, which should be feeding the speakers. Listen to the sounds produced by the speakers to determine if your connection is correct.

Other Types of Connections

Asides from trying to connect your mixer to your amplifier, there are some other things you can connect to your mixer for improved sound quality.

Connecting to a Powered Speaker

When connecting to a powered speaker, you don’t need to add an amplifier to the mix. Powered speakers already come with powered amplifiers and can work directly with your mixer.

You can use the same connection between a mixer and an amplifier, as we’ve discussed above. You will also need the same type of connector cables.

Connecting to Home Stereo Amplifier

Connecting your home stereo amplifier to your mixing board is possible, and the steps are the same as we mentioned earlier.

However, the input jack of a home amplifier might be different from the other amplifiers. You should check the type of input on the back of the amplifier and get one that works perfectly.

Also, don’t use the “phono” jack as it is inappropriate for use with a mixing board and can spoil your equipment.

Connecting to Monitor Speakers

Connecting to a monitor speaker is almost the same as usual, except you’ll use a different output jack on your mixer. So far, we’ve been using the main stereo output jacks, but in this case, it’s the C-R jack that matters.

With these variations, you should be able to connect your mixer to some other devices.

Things to Note

If you don’t have a lot of experience working with these pieces of equipment, it can all look very confusing at first. However, we are here to make it all simple for you, and we have some little pointers that will go a long way in ensuring a successful connection.


Safety is key, not only to prevent damage to your equipment but also to yourself.

Switch off every piece of equipment from the mixer to the speakers and amplifiers. If you leave the power on, there is a big chance of your speaker giving out loud bursts of noise upon connection. These bursts of noise can damage your equipment and alsoyour ears.

Aside from turning off all equipment, we advise you to reduce all the volume controls to the lowest. You can increase the volumes gradually after completing your connection, but not before, to prevent unexpected loud noises.

Develop the habit of powering off your amplifier first and the mixer next. Start with the mixer and then the amp when you want to switch them back on.

Neat Cable Arrangement

One rookie mistake is the poor arrangement of wires. Most times, we tend to leave the wires in a bunch. Leaving the wires tangled will not do any good, and it can cause a lot of interference in your audio output.

One tip to keep in mind is the length of the cable. We advise that you get the perfect length cables, preferably shorter. Avoid buying unnecessarily long cables because they seem convenient – these long cables are more prone to interference and noise generation.

Also, ensure that the cables are never bunched together. When you’re setting up, ensure that the cables are all independent and free of each other, you will notice that the sound will be much better.

Expect to Make Adjustments

Remember that the sound produced in your headphones will vary from the sound produced over the speakers. The mix you’ve listened to on your headphones might sound different when you’ve played it on the speakers but don’t panic.

Be ready to make adjustments based on what you can hear at the moment and not only what you’ve prepared.

Know Your Jacks

There are times when connections don’t work because we placed the wrong jack in the wrong output or something like that. Here are some ground rules to help master the jack placement.

  • All microphones should go into the point box.
  • Snake XLR connectors go with XLR connector inputs
  • The mixer’s main output and the picture equalizer’s input go together
  • The picture output signal goes with the home power amplifier input signal

If, after you’ve tried all the steps above, you still don’t get the desired result, here are some things you can double-check.

Common Problems Why the Mixer and Amp Connection Won’t Work

If you’ve tried to connect your amp and mixer to no avail, go through these points below to see where you went wrong.

Check Power and Volume

If you’ve followed our steps from the beginning, then you should have powered off all the equipment and turned down the volume. There is a good chance you’ve forgotten to switch one or more gears. Also, you might have forgotten to increase the volume on one of the pieces of equipment.

Ensure you double-check all power sources and volume control. You can also use your headset to test for sounds.

Check Your Cables

The connection of the cables is another potential source of the problem. Check where cables are involved, start with the connection between the mixer and the amplifier, and then move on to the amplifier and speakers.

Tighten any loose connection, and adjust cables overlapping or in a bunch.

Check for Fuses or Circuit Breakers

Most electrical devices come with protection mechanisms in case of irregularities in power. The amp and mixer also come with these defense mechanisms in the form of fuses and circuit breakers.

Your connection might not work due to a power overload and your circuit tripping off. Sometimes all you need to do is turn off the affected appliance and leave it cool for a few minutes.

Test Each Piece

If you’re finding it difficult to pinpoint the problem’s source, you can try testing each piece of equipment. You can connect your mixer to headphones and listen for sounds, try replacing the cables involved in your connection, and test the amplifier with different speakers.

Don’t Try to be an Expert.

If, after everything, you still can’t determine what is wrong with the setup, take it back to the store where you got it or a professional. We strongly advise you not to mess with equipment, resist the urge to open it up and check for what is wrong.

Also, if you’re using a powered speaker or amplified speaker, it is not advisable to use another external amplifier.

Connecting your amplifier to your mixer shouldn’t be much of a big deal if you can follow all the steps we’ve provided. If you have any difficulties along the line, retrace your steps and try to see where you went wrong. If you can’t find a way, contact an expert.
