A quality DJ mixer should be at the top of your list when investing in your DJ equipment. A DJ mixer board lets you control and manipulate the audio from multiple sources: record turntables, CD players, laptops, smartphones, tablets and more. With a mixer, you can make seamless transitions between tracks, add scratching and other sound effects or adjust levels as desired.
To add to the party atmosphere, you might also want to use a wireless microphone to pump up partiers with commentary and DJ lighting to add color that syncs with the beat. Over-ear headphones are essential for previewing tracks and cuing audio filters before playing them.
Additionally, if you are serious about music production, you can use music editing software to remix songs and create playlists for your DJ board. Doing creative work in advance will give you even more room to play when you are DJing an event.
