The amplifier features our proprietary high efficiency Class-ad topology for maximum power, sound quality and efficiency in full-range amplifier. It also integrates our patented Constant Power technology which results in up to 25% more output power. Top mounted controls feature our patented C.L.E.A.N. circuit to easily set your gains, integrated low-pass crossover, and our famous Punch EQ.
