Not every live sound situation calls for a huge line array and racks of equipment. When it comes to band practice spaces, small outdoor events, or open mics, a powerful-yet-portable PA system is generally all that's required. These compact, all-in-one systems give you a powered mixer to input your instruments and microphones and power the included speakers. Toss it in your car, show up to the gig, and be set up in minutes and ready to fill the room with sound. Shop Reverb's selection of new and used portable PA systems.
