DJ Mixer

A DJ mixer is a piece of hardware used by disc jockeys (DJs) to combine audio sources and sound effects during live performances. Beyond allowing the DJ to create his or her own audio through other sources, a DJ mixer makes it easier for a DJ to continuously play music without any downtime, so people keep dancing without interruption or a single moment of silence. In many ways, a DJ mixer unit is similar to other audio mixers, but there are differences in the DJ’s equipment that make a DJ mixer special. Most mixers can record audio, allowing the DJ to make an original mix that can be played on cue.

The DJ mixer is almost like any other audio mixer. It takes one or more audio sources and applies changes by altering the basic components of the audio’s sound. One of the defining features of a mixer is the crossfader, which acts as two faders colliding with each other. This allows the DJ to quickly transition from one song to the next, fading out one audio source and simultaneously fading in another source. Another defining feature is the ability to feed a non-playing audio source into headphones.


Aside from crossfading, DJ mixers have many other features that allow a DJ to create his or her own mix. There are often a variety of knobs and controls that permit the DJ to change the bass, treble and beat of the audio, along with other basic audio components. Sound effects are normally an afterthought with these units, so the DJ focuses more on mixing pre-existing music rather than adding sound effects, but most units have a few effects that can be used. These effects are typically generic and may be included on many different mixer models.

One obvious benefit from using a DJ mixer is that the DJ is able to keep music playing continuously without any downtime. This is done via the crossfader, because it generally allows the audio to decrease in volume for less than a second before picking back up. By using this technique, the DJ can keep people dancing and entertained all night, without there being any party-stopping silence between songs.

Another benefit of using a DJ mixer model is that the DJ can create his or her own DJ mixes. While some DJs prefer impromptu performances, others prefer to plan the event and have a list of songs and effects ready. DJ mixers can typically record a mix, so the DJ can have the lineup ready before the event occurs, and he or she can fine-tune the sound for his or her preference.

How Do I Become a Disc Jockey?

To become a disc jockey, it is usually necessary to go to college to acquire technical skills and training, whether the plan is to work in radio or club environments. It is also possible to acquire the necessary skills through apprenticeship and on the job training, although this can take longer. It also helps to be familiar with a wide variety of musical genres and to be able to keep pace with developments in the music industry through professional publications, events, and studious listening.

Radio disc jockeys need to be able to operate the equipment in the radio studio and also need some announcing skills. Many may give weather forecasts and other announcements during the show, and require training in broadcast journalism. In training, students learn how to use equipment and will also receive voice training so they acquire the vocal skills they need on the radio. Training to become a disc jockey often provides access to internships to allow students to get job experience.

A student who wants to become a disc jockey on a radio station may want to think about the kind of music that most interests her. She should develop broad familiarity with the genre she wants to work in. With a college education and some experience through internships, she can apply for positions at radio stations. Competition is often fierce, and it can help to have an outstanding application with credits like internships at major radio stations.

In the club environment, disc jockeys may not need broadcast journalism training, but it can help to have some education in music and audio engineering. Many colleges and universities offer this type of training. Disc jockeys can learn to operate sound equipment and may develop skills like mixing and playlist creation. Careers in clubs are less likely to require higher education, but applicants who choose not to go to college to become a disc jockey do need to acquire on-the-job training through internships under the tutelage of experienced disc jockeys.

It can take several years to become a disc jockey and even longer to build up a reputation in the field. Radio announcers may move between stations to take advantage of better job offers and more work opportunities, while club disc jockeys tend to develop freelance careers as they build up a list of clients and a following. Both can potentially become celebrities if they have charisma and a talent for adapting quickly to emerging trends in music; a disc jockey can attract a customer following that will put him in high demand and may allow him to negotiate better pay for his services.

4-Channel Mixer

Components used to combine audio sources are called mixers because they mix multiple audio sources into a combined output. An audio mixer can include dozens of inputs, with advanced features to provide sophisticated signal routing to a variety of destinations. A smaller 4-channel mixer typically has only four channels to handle incoming audio sources, but can have multiple audio output channels. Generally, a 4-channel mixer is designed to solve more basic audio problems.

Disc Jockeys (DJs) typically use a 4-channel mixer to combine two stereo audio sources so music can be cross-faded from one song to another. Mobile audio production crews for film or television may use a 4-channel mixer to combine audio from two actors while also capturing the ambient sound from the location. The mixers are frequently used in conjunction with a public address (PA) system where solo performers need to blend a vocal microphone with an instrument. A 4-channel mixer might also be used in an auditorium where a group of speakers each require their own microphone.

Most 4-channel mixers include design features for specific applications. A mixer used by DJs typically will feature slider controls that are well suited for smooth transitions between sources. Mobile audio production units might use rotary knobs so an accidental bump will not cause an unwanted adjustment of the volume level. Depending on the application, mixers may also provide light-emitting diode (LED) displays that warn when input levels are too high, or a larger multi-color LED display that shows output levels.

Regardless of the number of inputs provided, mixers often include additional features to further control the audio signal. These features might include equalization for each channel. Equalization allows the user to adjust different parts of the audio spectrum. Reducing low, or bass, frequencies can help reduce feedback problems. Reducing high, or treble, frequencies reduces hiss or noise created by the input source.

Some mixers include the ability to send a separate audio level to additional outputs. A musician may need to hear themselves through a stage monitor, as well as send a separate audio level to the PA system. Mixers can allow performers to adjust both the stage monitors and the sound heard by the audience by having separate controls for each output. The cost of the mixer typically will increase with the number of added features.

A well-designed audio mixer generally will operate without adding additional noise or distortion from its internal electronic circuits. Mobile mixers used by musicians or mobile applications are designed to endure the bumps and scrapes that happen with frequent movement. As needs grow, 4-channel mixers can be replaced by models that feature more inputs for additional audio sources.

Radio Disc Jockey

A radio disc jockey, also known as a DJ, is a person who works at a radio station. He or she is responsible for playing music and broadcasting news on the radio. The radio disc jockey may also read commercials on air and accept calls from listeners. Whether presenting a traffic or weather report, chatting with listeners by phone, or interviewing celebrities, a radio disc jockey must do so in a relaxed, professional manner.

Disc jockeys sometimes gain their training in radio broadcasting by earning a degree in broadcast journalism. They then find an internship at a radio station, receiving hands-on training in the field. Other aspiring DJs may work at school radio stations before becoming a professional disc jockey. No matter which path a future DJ takes, radio broadcasting is a competitive field that proves difficult to enter.

People with clear speaking voices and the ability to learn complex equipment have the best chance of finding work as a radio disc jockey. Disc jockeys usually specialize in specific genres of music, so they must be familiar with different music styles. They must also be able to speak in a knowledgeable manner about their chosen genres.


During a typical work schedule, DJs must manage their time well. This involves knowing the amount of time available so that music, commercials, news, interviews, and chatting fit into a set schedule. They must also have the ability to operate complex equipment that controls music and sound. DJs who play club music must be skilled at mixing music and beats as well.

Since radio stations play music 24 hours a day, a disc jockey may be required to work unorthodox hours. Many work late nights and weekends. More established DJs with a loyal following may work more desirable time slots. It's important that the new DJ develops a pleasing on-air personality so that listeners continue to listen to his or her radio program.

Disc jockeys do more than just present prerecorded music on the radio. They also may be responsible for writing commercials and skits. After writing the scripts, they perform the material. Disc jockeys are often required to do promotional work, making public appearances at community events and visiting schools.

Since the disc jockey is usually responsible for playing new music on the air, music companies often send the new albums of their recording artists for the DJ's review. This provides the DJ with opportunities to hear the latest music. As a result, disc jockeys stay abreast of trends and sometimes have the chance to influence the tastes of the listening public.

What Are Different Types of Disc Jockey Jobs?

Disc jockey jobs include those that are performed at a radio station, club or special event. In some cases, a disc jockey may do more than one of these types of jobs, either making special appearances for a radio station as a promotion, or to earn money on the side. No matter what career path is chosen, many disc jockey jobs are very similar. Even those inside a radio station often require a great deal of public interaction.

It is for this reason that most disc jockey jobs are not merely jobs that require selecting songs and running a broadcast, though these may be very important aspects of the disc jockey job description. Rather, a disc jockey must be a person that relates well to people. In the studio, the disc jockey is often one of the first contacts the general public has, answering a studio line to take requests, running contests and other interactive experiences. Disc jockeys that enjoy this type of work will find there are plenty of opportunities, as the most popular ones will have a great deal of public interaction.
Radio disc jockey jobs involve doing show preparation, running the broadcast, and dealing with listeners. In some cases, a disc jockey will be responsible for securing interviews with local personalities, or personalities within the music genre. In other cases, the format may simply call for playing music, updating sports, news and weather, and handling other general duties. While a disc jockey shift may last eight or more hours, they are seldom on the air that long.

Other disc jockey jobs are based at night clubs. These are usually part-time positions. The person performing the duties of a disc jockey in this setting is therefore likely to be a student, or will have another full-time or part-time job. Further, a live disc jockey may be required every night of the week at busier clubs, or only on weekends, depending on the crowd levels and expectations. This type of job can provide a good, steady part-time income for those interested in the work.

For those who want to start their own business, becoming a disc jockey is one way to do it. Privately-contracted disc jockeys are often in demand for weddings and other special events. Due to the fact many of these events happen on weekends, it is very easy for an individual to also have a full-time job. Doing this type of job on the side will require investment in equipment, lighting and sound systems. This could get to be very expensive.

How Do I Become a Mobile Disc Jockey?

A person looking to become a mobile disc jockey will need to have a love for music and the ability to operate DJ equipment proficiently. It is possible to get a start in the industry by visiting local disc jockey companies and seeking employment or by starting a mobile disc jockey entertainment company. An aspiring mobile disc jockey needs to have a broad knowledge of various music genres, and a desire to entertain a crowd. Although there are several training programs available, there is no specific training that is required in order to become a mobile disc jockey.

The duties of a mobile disk jockey include traveling to a variety of venues with the expectation of being able to play any genre of music required by the client. A fun and outgoing personality is also needed in order to become a mobile disc jockey, as the job demands that the DJ keep the crowd excited and engaged throughout the session. The skills needed to please a crowd and keep guests engaged in the music can either be self-taught or learned through watching and listening to other disc jockeys.

It is important to keep in mind that although being a disc jockey might appear to be all fun-and-games, it is serious work. An aspiring mobile disc jockey will need to work tirelessly at promoting his services in order to find clients and gigs. This is quite challenging in comparison to the typical disc jockey job where one has a regular show at a local radio station or nightclub. A marketing plan will also be needed in order to determine the best method for attracting clients, whether for weddings, parties, or any other event that requires mobile disc jockey services.

In order to become a mobile disc jockey, it is necessary to develop good contract terms to present to potential clients. New DJs will need to outline their services and payment policies in order to focus their attention on their specialties and ideal clients. Having structured pricing guidelines will also help to attract serious customers and quickly filter out unqualified leads.

Finally, in order to become a successful mobile disc jockey, time management skills are critical. Good mobile DJs always work with a business calendar in order to manage their schedules. Fridays and weekends are usually the busiest times on the schedule and many even find themselves booked months in advance. Aspiring mobile disc jockeys must learn how to maintain a business calendar and manage appointments.

What Are the Different Types of Audio Computer Software?

Audio computer software changed the way consumers perceive music. With these computer programs, consumers went from simply listening to music, to having the ability to listen to, record, or manipulate music files. Different types of audio computer software include players that allow a consumer to listen to different types of music files, recorders that allow consumers to record music, editors that allow consumers to improve or change music files, and converters that allow consumers to change the file type of different music clips.

Music player software is the most common type of audio computer software. With a music player, the owner can play music files directly from a CD, play files stored on his or her computer, or stream music from a website. Many music players also allow the user to create a library of all of their music files within the player itself and to make different playlists using multiple albums.

Recorders have two main functions, including the ability to record from a CD and the ability to record from a voice recorder. The user can use the recording software to transfer his or her CD collection to computer files and store the files within the computer itself. The recording software can also work with a computer's voice recording software, so the user can record his own original music or record streaming music from other sources saving the music as a file on his or her computer.

Editors give the user the most control over his or her music collection, including both music files from other artists and music files of his or her original recordings. This type of auto computer software allows a user to edit different music files using different settings and filters. For example, the user can shorten the length of a file, mix two files together to create a new sound, or add sound effects to an original recording.

A converter is a type of audio computer software that allows the user to change the file type of different music files. Many portable music players only accept one or two file types, such as mp3 or mp4. With a converter, a user can change the file type of all of his music files to match the file type accepted by his portable music player. Some converters also include basic editing features, such as a sharpness filter that removes static or excess noise from the file during conversion.
