MIDI input and output jacks allow you to use devices like keyboards, controllers, synthesizers, and drum machines. Separate TRS and RCA output jacks provide multiple options for connecting DJ mixers, monitors, and other gear. Finally, an independent headphone output with dedicated volume control gives you complete flexibility while monitoring.
