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 Balanced Current Amplifier (BCA®) circuitry, Crown® 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. As with all convection-cooled amplifiers, varying operating levels and loads may require additional air movement in high ambient temperature conditions. K-Series amplifiers are so energy efficient— more than twice that of conventional switching amps—they require significantly less energy to deliver their massive power into virtually any load, no matter how difficult. In addition, each amplifier is equipped with a “green” circuit that further reduces energy use during idle periods. Energy draw is so low—only 12 watts or less—the amplifier may be kept in a continual ready state at minimal cost. This efficiency means you’ll realize significant savings over the life of the amplifier, reducing the cost of ownership, as well as enabling more K-Series amplifiers to be plugged into a single AC circuit, reducing installation costs.
Features • Accurate, uncolored sound with very low distortion for the best in music and voice reproduction • High damping factor for tight, clean bass response • Advanced design for energy conservation • Mono mode switches allow you to set up your amps/speakers in the configuration that best suits your needs—with combined amp inputs, combined amp outputs, or both. • Advanced protection circuitry guards against: shorted outputs, open circuits, DC, mismatched loads, general overheating, high-frequency overloads and internal faults • Extremely versatile, handling a wide range of speaker impedances and outputs • Exclusive BCA® (Balanced Current Amplifier) power design provides super efficiency for quiet, fan-free operation • Switchable input sensitivity • “Soft start” feature prevents the K-Series amplifier from drawing large currents when it is first turned on so you don’t need to delay power-on of your amps • Uniquely molded, cast-aluminum front panel provides exceptional air circulation for your KSeries
