K Series amplifiers deliver more power and sound while using less energy than conventional amplifiers. And it's all in a durable, maintenance-free package that's just two rack spaces high. Using patented BCA® circuitry, K Series amplifiers give you massive amounts of power while generating just one-tenth the heat of conventional amplifiers. In fact, the powerful K2 amplifier can deliver an amazing 1,250 watts per channel into 2 ohms (and that's a very solid 2 ohms)! Because of their incredible efficiency, K Series amplifiers require no internal cooling fan and feature a closed chassis. Of course, no fan means no fan noise. In addition, the closed chassis makes these amplifiers virtually immune to environmental problems such as dust, cigarette smoke, stage fog and spilled liquids. In practical, everyday terms, the K Series amplifiers are essentially maintenance-free. Your investment is backed by an unequaled three-year, no fault, full warranty that covers everything.
