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.
 
The amplifier also features high and low level inputs combined with our differential inputs to eliminate incoming noise.  It can also provide a remote-out trigger when using high level inputs. Dual fan cooling, real time thermal monitoring and dual extruded heat sinks maintain heat dissipation even at high outputs keep the amp cool.
