Servo 260

Power Amplifier

A mainstay of our popular Servo amplifier line, the 260 can be used to power near field monitors, passive headphone distribution systems in the studio and small live sound reinforcement setups. It is also a great choice for stereo keyboard or guitar amp setups with external mixer or preamps or amplifying a large screen TV or video system. The Servo 260 is dedicated to transparent audio, consistent performance and the rugged construction you need from a professional amplifier.
