The Peavey XR Series of powered mixers is a mainstay of the music industry. When the first XR Series mixer premiered in 1977, it began a standard of power and quality that is diligently maintained today. As the years have passed, Peavey has maintained its reputation for quality, durability, power and progress with technological innovations, such as DDT™ (Distortion Detection Technique) and FLS™ (Feedback Locating System).
