A DJ mixer is a type of audio mixing console used by disc jockeys (DJs) to control and manipulate multiple audio signals. [1] Some DJs use the mixer to make seamless transitions from one song to another when they are playing records at a dance club. Hip hop DJs and turntablists use the DJ mixer to play record players like a musical instrument and create new sounds. DJs in the disco, house music, electronic dance music and other dance-oriented genres use the mixer to make smooth transitions between different sound recordings as they are playing. The sources are typically record turntables, compact cassettes, CDJs, or DJ software on a laptop. DJ mixers allow the DJ to use headphones to preview the next song before playing it to the audience. [2] Most low- to mid-priced DJ mixers can only accommodate two turntables or CD players, but some mixers (such as the ones used in larger nightclubs) can accommodate up to four turntables or CD players. DJs and turntablists in hip hop music and nu metal use DJ mixers to create beats, loops and so-called scratching sound effects. [3]

Description

DJ mixers are usually much smaller than other mixing consoles used in sound reinforcement systems and sound recording. Whereas a typical nightclub mixer will have 24 inputs and a professional recording studio's huge mixer may have 48, 72 or even 96 inputs, a typical DJ mixer may have only two to four inputs. The key feature that differentiates a DJ mixer from other types of larger audio mixers is the ability to redirect (cue) the sounds of a non- playing source to headphones, so the DJ can find the desired part of a song or track.

A crossfader has the same engineering design as fader, in that it is a sliding control, but unlike faders, which are usually vertical, crossfaders are usually horizontal. To understand the function of a crossfader, one can think of the crossfader in three key positions. For a DJ mixer that has two sound sources connected, such as two record turntables, when the crossfader is in the far left position, the mixer will output only turntable A's music. When the crossfader is in the far right position, the mixer will output only turntable B's music. When the crossfader is at its midpoint (which is always marked with a horizontal line), the mixer will output a blend of turntable A's music and turntable B's music. The other points along the crossfader's path produce different mixes of A and B.

DJ mixers typically have phono preamplifiers to hook up turntables. The signal that comes directly out of a vinyl turntable is too weak to be amplified through a PA system. Before a turntable can be usable in a mix, it needs to be preamplified. DJ mixers are also used to create DJ mixes, which are recorded and sold. DJ mixers usually have equalization controls for bass and treble of each channel. Some 2010-era DJ mixers have onboard electronic or digital effects units such as echo or reverb. Some DJ mixers also feature a built-in USB sound card to connect to a computer running DJ software without requiring a separate sound card. DJ mixers typically have a microphone input, so that a microphone can be plugged into the mixer, enabling the DJ to announce songs or act as a master of ceremonies (MC) for an event. Some DJ mixers have a kill switch, which completely cuts out a channel, or, on some models, completely cut out a frequency band (e.g., all the bass). [4] [5]

Outputs

The output from a DJ mixer is typically plugged into a sound reinforcement system or a PA system at a dance, rave, nightclub or similar venue or event. The sound reinforcement system consists of power amplifiers which amplify the signal to the level that can drive speaker enclosures, which since the 1980s typically include both full-range speakers and subwoofers for the deep bass sounds. If the DJ is performing a mix for a radio station or television station, the output from the DJ mixer is plugged into the main audio console being used for the broadcast. If the DJ is performing a mix that is being recorded by a recording studio, the output from the DJ mixer is plugged into the main audio console used for the recording, which is in turn plugged into the recording medium (audiotape, hard disk, etc.). In some cases, such as when a DJ is performing a set at a club for dancers that is also being simultaneously broadcast over the radio or television system or recorded for a music video or other show, the output from the DJ mixer is plugged into the sound reinforcement system and into the main audio console being used for the broadcast and/or recording. At club sets, some DJs may use a monitor speaker to hear the house's main mix. This monitor speaker can have its volume increased or decreased by the DJ as needed. [6]

Power

DJ mixers have an AC mains plug that is connected to the wall to supply electric power for the unit. Some DJ mixers can take batteries, which enables users to mix songs outside or away from electric power sources, with the output being plugged into a portable boom box or other battery-powered sound system.

History

DJ mixing played a key role in the development of the African-American style of hip hop music. In hip hop music and occasionally in other genres that are influenced by hip hop (e.g., nu metal), the turntable is used as a musical instrument by DJs, who use turntables along with a DJ mixer to create unique rhythmic sounds and other sound effects. Manipulation of a record as part of the music, rather than for normal playback or mixing, is called turntablism. The basis of turntablism, and its best known technique, is scratching , pioneered by Grand Wizzard Theodore. It was not until Herbie Hancock's "Rockit" in 1983 that the turntablism movement was recognized in popular music outside of a hip hop context. In the 2010s, many hip hop DJs use DJ CD players or digital record emulator devices to create scratching sounds; nevertheless, some DJs still scratch with vinyl records.

DJ mixing also played a key role in disco music in the 1970s. In disco clubs, DJs would use mixers to transition seamlessly from one song to another and create a mix of songs that would keep the dancers energized. One of the pioneers of DJ mixing equipment design was Rudy Bozak. Beatmatching and beatmixing with a DJ mixer were first used to encourage dancers not to leave the dancefloor between songs. By beatmatching song A and song B, a DJ can transition seamlessly between two songs, without creating a break in the music. Typically, when a DJ is using beatmatching, they will let song A play until it nears its end. As song A is playing, the DJ "cues up" song B in their headphones and adjusts the speed of record player B until the beats of song A and song B are synchronized ("synced up"). Then, once the two songs' beats are synchronized, they can slowly fade in song B while song A is nearing its ending. In the 2000s, DJ mixers have been used for harmonic mixing.

Beatmatching or pitch cue is a disc jockey technique of pitch shifting or timestretching an upcoming track to match its tempo to that of the currently playing track, and to adjust them such that the beats are synchronized—e.g. the kicks and snares in two house records hit at the same time when both records are played simultaneously. Beatmatching is a component of beatmixing which employs beatmatching combined with equalization, attention to phrasing and track selection in an attempt to make a single mix that flows together and has a good structure.

Turntablism is the art of manipulating sounds and creating new music, sound effects, mixes and other creative sounds and beats, typically by using two or more turntables and a cross fader-equipped DJ mixer. The mixer is plugged into a PA system for live events and/or broadcasting equipment so that a wider audience can hear the turntablist's music. Turntablists manipulate records on a turntable by moving the record with their hand to cue the stylus to exact points on a record, and by touching or moving the platter or record to stop, slow down, speed up or, spin the record backwards, or moving the turntable platter back and forth, all while using a DJ mixer's crossfader control and the mixer's gain and equalization controls to adjust the sound and level of each turntable. Turntablists typically use two or more turntables and headphones to cue up desired start points on different records.

Essayist Geoffrey O'Brien described this definition of the mixtape as "perhaps the most widely practiced American art form".

<span class="mw-page-title-main">Controllerism</span> Art of using musical software controllers

Controllerism is the art and practice of using musical software controllers, e.g. MIDI, Open Sound Control (OSC), joystick, etc., to build upon, mix, scratch, remix, effect, modify, or otherwise create music, usually by a Digital DJ or Live PA performer, often called a controllerist. Controllerism is also a nod to traditional musicianship and instrumental-ism paired with modern computer sequencing software such as Ableton Live and Native Instruments Traktor. However a working knowledge of scales and chords is not necessarily required as the performers typically focus their efforts more on sequencing events, software effect and instrument manipulations using buttons, knobs, faders, keys, foot switches and pedals than on instrumental notes played in real time. With recent developments in music technology, particularly in software instruments, a USB MIDI controller enables musicians almost unlimited possibilities to control a wide variety of sound types.

<span class="mw-page-title-main">Professional audio store</span> Retail business

A professional audio store is a retail business that sells, and in many cases rents, sound reinforcement system equipment and PA system components used in music concerts, live shows, dance parties and speaking events. This equipment typically includes microphones, power amplifiers, electronic effects units, speaker enclosures, monitor speakers, subwoofers and audio consoles (mixers). Some professional audio stores also sell sound recording equipment, DJ equipment, lighting equipment used in nightclubs and concerts and video equipment used in events, such as video projectors and screens. Some professional audio stores rent "backline" equipment used in rock and pop shows, such as stage pianos and bass amplifiers. While professional audio stores typically focus on selling new merchandise, some stores also sell used equipment, which is often the equipment that the company has previously rented out for shows and events.
