Generally speaking, PA Mixers are designed to simply be a volume control for many audio sources, whereas DJ Mixers are designed for 2 or 4 audio inputs and feature a cross fader that is specifically designed to blend music sources.
Unlike PA Music Mixers, DJ Mixers are designed to be smaller, often designed to fit between two DJ Turntables or DJ CD Players. DJ mixers come in many ranges and sizes with many features.
The DJ Mixer is a DJ equipment tool that is designed to allow seamless blending of music and other audio sources.
In the 1970s a collective of vinyl DJ turntables, amplifiers and speakers were referred to as Disco Equipment. This was due to a genre of music at the time known as disco. Since the introduction of multi-coloured (sometimes flashing) lighting in the late 1960s to early 1970s most equipment used by DJs has been referred to as Disco Equipment.
A DJ turntable is a record player that has pitch control and a removable phono cartridge.
A DJ CD player can be either a twin CD player or a DJ CD turntable.
A DJ mixer is a device that allows two or more sources of music to be blended together.
A DJ speaker is similar to a hi-fi speaker, with the exception that it is generally much larger and handles more power.
It all seemed to start with the Technics SL-1200 turntable. The Technics SL1200 turntable started out life as a high quality hi-fi turntable. However, unlike other turntables, the SL1200 had a very rare feature... Pitch control. The pitch control feature allowed the user to change the speed of their music to suit their ears.
However, some people had a better idea. Since most songs are a different speed, seamlessly blending them would require the speed of the BPM to be changed. The Technics SL1200 allowed the user to do this. Subsequently, Technics released their Technics SL1200 MK2 in the early 1970s which was designed with the DJ in mind.
Whilst there have been many competitors in the DJ turntable market, namely the Citronic PD-1 DJ Turntable the Numark TTX DJ Turntable, nothing has ever really been able to knock Technics SL1200 off the top-spot. Soon after the release of the Technics SL-1200 MK2, Technics released their Technics SL-1210 MK2 which was identical in every way, except for its colour.
