The Crown K2 is a high-power, efficient, convection-cooled professional amplifier delivering up to 1,250 watts per channel into 2 ohms with a high damping factor and compact 2U rack design.Power and Performance
The Crown K2 uses Balanced Current Amplifier (BCA®) circuitry, allowing it to deliver 1,250 watts per channel into 2 ohms, 850 watts into 4 ohms, and 500 watts into 8 ohms, all with very low distortion and high efficiency
. It features a damping factor greater than 3,000 from 10 Hz to 400 Hz, ensuring tight control over speaker drivers, particularly subwoofers
. The amplifier operates fanless, relying on convection cooling, which eliminates fan noise and reduces maintenance
.
Inputs and Outputs
The K2 provides XLR balanced inputs and 5-way binding post speaker outputs. While RCA inputs are not included, balanced 1/4″ phone jacks can be used if necessary
. Sensitivity adjustments and gain controls allow precise matching to various audio sources.
Physical Dimensions and Weight
The amplifier is 19 inches wide, 3.5 inches high (2U), and 16 inches deep, making it compact for professional rack installations. It weighs 38 pounds, allowing for easy stacking and transport
.
Efficiency and Energy Use
The K2 is highly energy-efficient, requiring significantly less power than conventional amplifiers and drawing only 12 watts or less in idle mode. Its closed chassis design protects against dust, smoke, stage fog, and spills, making it virtually maintenance-free
. A “green” circuit further reduces energy consumption during idle periods.
Additional Features
- Convection-cooled, fanless design for quiet operation
- Closed chassis for environmental protection
- Exotic protection circuits to safeguard the amplifier and connected speakers
- Made in the USA with robust construction
The Crown K2 is ideal for professional audio setups requiring high power, reliability, and low maintenance, particularly in live sound, studio, and subwoofer applications.
