Independent radio stations require 5 main pieces of equipment: a controller to control music and jingles alongside DJ software, a mixer to combine audio signals, a compressor/limiter to regulate sound levels, a laptop to run DJ software and access social media, and a microphone and headset for mixing and presenting. Commercial radio stations require additional equipment like multiple computers and monitors dedicated to specific tasks, radio station software to store and play songs, commercials, and jingles, digital cart walls and playlists to prepare content before shows, and digital playback systems to schedule and track songs.
