An electronic device that is crucial for sound processing is known as a mixer (or mixing console). This piece of equipment is a common term among individuals who work with audio, such as musicians, operators, radio and television employees, DJs, and event organizers. However, it isn’t just professionals who can benefit from having a mixer. Even for small family gatherings, performances by novice musicians, or amateur video and audio recordings, a mixer is essential in preventing sound chaos and creating a harmonious auditory experience. In this article, we will explore the purpose of a mixer, the various applications it is used for, and how to select the right device to suit specific requirements.
What a mixing console is for
Volume, pitch, and timbre are the distinguishing characteristics of various sounds. When left to their own devices, these sounds can blend together, overpowering each other and creating unpleasant combinations that are not pleasing to the human ear. When in large spaces, it becomes necessary to amplify the sound in order for it to reach all listeners, especially those who might be farther away from the sound source. However, a simple increase in volume can negatively impact the audio quality, resulting in distortions such as rattling and noise. Additionally, the low tones can become overly heavy, while the high tones can become piercing and harsh. To avoid these undesirable effects, it is necessary to preprocess individual audio tracks and then combine them, which is precisely what a mixer does.
How a mixer works
- Balance the volume;
- Process the frequency (modifying the frequency of the signal can enhance the sound quality, while removing unwanted frequencies can equalize the sound and eliminate interference);
- Apply various effects.
Afterwards, the separate signals are merged together to form a unified audio track and stored in a file (special software needs to be installed on a laptop or desktop computer) or transmitted to an output device (such as a speaker or speakers).
By the way! Any settings made during the process can be saved, which means that you won’t have to readjust the required parameters for similar projects in the future.
Types of mixing consoles
There are various types of mixer consoles available, which are classified based on different factors such as the audio signal format, device size, and primary usage purpose.
By the way of working with sound
The classification of sound mixers is based on their representation method, which can be either analog or digital. In analog devices, sound is represented as a continuous electrical signal, while digital devices convert the sound wave into a series of numbers that represent the amplitude of the audio signal at specific points in time.
By size
There are different types of mixing consoles, which can be classified based on their dimensions and installation method:
- Stationary consoles are commonly used in professional recording studios and large concert venues. They are designed to handle a large number of signals and are characterized by their imposing size and weight.
- Portable consoles, as the name suggests, are designed to be easily transported and used in various locations. They are smaller in size compared to stationary consoles.
Both stationary and portable consoles serve different purposes and can be chosen according to the specific needs and requirements of the user.
Portable devices are typically more compact and lightweight compared to their stationary counterparts. Generally, these consoles are equipped with a maximum of 20 channels, making them convenient for transportation to and from studio setups, live performances, or off-site functions.
Portable equipment typically consists of 6 to 8 channels and is characterized by its small size and light weight. These types of mixers are particularly useful for small festivals, performances that already have sound accompaniment, amateur concerts, and even for recording audio at home.
By purpose
There are several different types of mixing consoles based on their intended use:
- Studio consoles are designed for multi-channel recording of music and soundtracks.
- Concert consoles are used for live performances or when working with pre-recorded tracks.
- DJ consoles are specifically designed for working with samples, vinyl records, and adding special effects during a DJ performance in clubs or discos.
- On-air consoles are used in radio and television stations for broadcasting pre-recorded tracks, live music, speeches, and handling incoming calls.
- Universal consoles can handle various tasks and are suitable for different purposes.
Each type of mixer console serves its own specific purpose. However, universal consoles are not recommended for complex projects that require high sound quality.
How a mixer is organized
There are various distinctions between different types and models of consoles, but all devices for processing and blending sound share certain components. The device includes:
- an inputs section;
- an output section;
- controls.
The input channels are divided into mono and stereo, with the latter having two inputs per signal. Each monaural channel has two jacks: one for a line input and one for a microphone input. Stereo channels do not have microphone jacks.
On another note, many mixer models feature volume-balanced and noise-cleaned inputs for each input signal. These inputs are referred to as balanced inputs.
After processing, the signals are grouped and directed to the output channels. Among them, line outputs stand out – connectors that are specifically designed for outputting sound to external devices.
The sound can be adjusted using rotary knobs or sliders, as well as switches in the form of buttons or levers. It is possible to turn on or off individual channels to listen to the processed result. The number of controls depends on the number of channels.
In digital mixers, signal information is often displayed on a compact LCD screen. Some models offer the convenience of being controlled via a mobile device, but this requires the installation of a program from the official equipment manufacturer’s website.
Documentation for the mixing console contains information about voltage parameters at the inputs and outputs, types of connectors, the function of controls, and other relevant details. Instructions accompanied by illustrations and symbols will assist both novice and experienced users in preparing for their tasks.
Where mixers are used
Studios that engage in professional sound recording, such as musical compositions or soundtracks for movies, make use of equipment that boasts a plethora of channels. Meanwhile, concert venues require a dedicated console to smoothly organize performances. On the other hand, portable devices are the ideal choice for small-scale events such as holidays, public gatherings at shopping and entertainment centers, as well as educational institutions. One of the advantages of utilizing mobile consoles is that they come equipped with a built-in sound amplifier, eliminating the need for a separate device that would need to be transported from one location to another.
Broadcasting consoles are utilized in television and radio broadcasting. DJ consoles can be discovered not only in nightclubs – compact models are employed at festivals: corporate parties, weddings, family celebrations. For beginners, non-professional teams, as well as individuals in need of straightforward sound support, portable mixers are ideal. Instructions on how to connect them can be found in the corresponding section.
Pros and cons of mixing consoles
There are pros and cons to each type of mixing console. These advantages and disadvantages are often related to their applications, rather than their direct purpose. For example, a portable console might be used for a concert. However, there are also general praises and comments about each type, which are summarized in the table below.
| Analog | Digital | |
| Advantages | Analog devices are cheaper and easier to learn. They have a relatively simple design, making them easier to repair. These mixers are also considered the most reliable and can last for more than 10 years. | Digital devices are much smaller and lighter compared to analog mixers.
