Common live sound sources are microphones (for vocals, speech, acoustic instruments, and instrument amplifiers), electronic instruments, DJ decks, and audio players.

In addition to combining multiple sources while adjusting their relative levels, a mixer provides the necessary preamplification for microphone and line level sources, and can be used to apply equalization, dynamics processing, and/or effects.

The line-level output from the mixer is fed to one or more amplifiers that provide the power needed to drive the system's speakers. Some mixers and speakers have built-in power amplification, reducing the number of separate components required and enhancing portability.

Speakers convert the electronic signal from the system's power amplifier(s) into audible sound. A dazzling variety of speakers and speaker systems are available, so unless you're planning on acquiring a preconfigured package you will need to carefully choose models that suit the specific application.

How to Mix Live Music

Chapter 1 - Introduction

You will learn how to use each feature of these mixing consoles, and how to apply them practically to your regular music mixing jobs. We have lots of tips, tricks, advice and experience to share with you. When you know what you’re doing, mixing live music becomes a whole lot more enjoyable and creative.

Chapter 2 - Which Console?

In this video, we will talk about how to choose the right mixing console for your work, and what tools and accessories you should always take to work!

Chapter 3 - Get Connected

In this 3rd part of the training series “How To Mix Live Music”, we are going to get the mixing console connected to all the other sound equipment: microphones, amplifiers and loud speakers. You should aim to do all your connecting before switching on the power! But before we begin connecting, let’s do some planning!

Chapter 4 - Microphone

Before we start using the mixing desk, we are going to talk about microphones: how to choose the most suitable types, and where to put them for the most common types of instrument!

Chapter 5 - Inputs

Last time we chose our microphones, and placed them near the instruments on stage. Now we’re going to bring the sounds from the stage into our mixer, and make the optimal settings for each input.

Chapter 6 - Gain Structure

This time we have a very important topic, which I have witnessed even some seasoned professionals get wrong from time to time. It is “Gain Structure”. It is crucial to understand if you want to get a clean and consistent mix every time!

Chapter 7 - HPF

In Chapter 7, we will see how a small button can be a big help: it's the “High Pass Filter”. So our first question: what is a “High Pass Filter”? High Pass Filter is one of the most useful tools on a live mixing console, as it leaves all the high frequencies alone, while filtering out the un-necessary low frequencies.

Chapter 8 - Introducing EQ

This video will give you an introduction to the types of EQ available on most popular analog and digital live mixers, and it will help you understand how to operate all the controls safely.

Chapter 9 - EQ for Outputs

This time we will be EQing our outputs, that is the speakers for the audience and for the performers on stage. If you get this right first, it is going to be easier to EQ all the input channels. Taking time to work on the outputs first will save time when working on the inputs later.

Chapter 10 - EQ for Drums

In this chapter, we will focus on drums as in kick, snare, hat, toms and overheads, probably the loudest instruments in the band, and the ones with the most focused range of frequencies. Each mic used will require different treatments.

Chapter 11 - EQ for Electric Bass, Guitars & Keyboards

We've already got the drums sounding good, now we are going to move on to the electric bass, guitars and keyboards, the key instruments for most rock and pop bands.

Chapter 12 - EQ for Acoustic Instruments

Now we are going to start applying EQ to acoustic instruments such as guitar, violin and brass. Some of these instruments are quite sensitive and care needs to be taken to avoid feedback. Even electro acoustic guitars that is hollow-bodied guitars with built-in electronics to capture the sound. They can feed back if placed close to a stage monitor speaker.

We will introduce how a mixer works, this is the most important role in the "Signal Flow" of the PA system. We will use the MG16XU 16 channel mixer as an example.

* No sound comes out if any of [2] [8] [9] is down.


From microphones to musical instruments, playback devices and more.


Before you can begin to mix sound, you have to adjust the input gain for each channel first.


By narrowing the dynamic range (the difference in volume between loud and soft) you can fine tune both your vocals and instruments to get the best sound for your venue.


You can adjust the sound quality by using the 3-band equalizer for High, Mid and Low frequencies. By boosting High frequencies, you can add clarity and presence. Boosting Mid frequencies can help make vocals easier understand, and by adding Low frequency you build “Bottom End” giving the mix more power.


The PAN knob adjusts the channel to the left, right or center of the mix, this is especially useful when using stereo signals from a playback device, synthesizer or electric piano.


When the channel is not being used, you can mute the channel output.


By engaging this button, you can send the channel output directly to the main stereo out on the mixer.


The fader is used to increase or decrease the output volume for that channel. In order to keep your gain to 0db, make sure to adjust the channel input gain (2) first.


This adjusts the final mix signal up or down to the system amplifier in a passive speaker system, or directly to the speakers in an active speaker system.


You can monitor the overall system gain with the level meter. When the Peak light comes on, you are overdriving the system and could cause damage to amplifiers and speakers.


These are the Left and Right main output signal that are sent to the power amp or powered speakers.
