We at B-52 believe in overbuilding all of our products and the US-Series Professional Power Amplifiers are no exception. We took our time in designing these stellar looking amps to outperform the competition on any stage, in the clubs and on the road. To achieve studio quality audio reproduction we utilized low noise, low distortion circuitry and high current output stages. We used oversized toroidial transformers and large filter capacitors to deliver super clean, fist pumping output even when driving a 2 ohm speaker load. These amplifiers use the most reliable linear output devices which provide ultra low distortion and ruler flat frequency response. The US-Series is backed by our rock solid 1-year warranty and our commitment to reliability known the world over.
