1 Welcome

Congratulations on purchasing a Crown®

K Series amplifier. It is designed to provide very high power in a lightweight package, without using a cooling fan. This means your amp runs quieter (no fan noise) and cleaner (no need for filters). The K Series amplifiers are very energy- efficient as well.

Modern power amplifiers are sophisticated pieces of engineering capable of producing extremely high power levels. They must be treated with respect and correctly installed if they are to provide the many years of reliable service for which they were designed.

In addition, the K Series amplifiers include a number of features which require some expla- nation before they can be used to their maxi- mum advantage.

Please take the time to study this manual so that you can obtain the best possible service from your amplifier.

1.1 Features

•Accurate, uncolored sound with very low distortion.

•High damping factor for tight, clean bass response.

•Advanced design for energy conservation.

•Versatile, handling a wide range of speaker impedances and outputs.

•Switchable input sensitivity.

•“Soft Start” feature prevents the amplifier from drawing large currents when it is first turned on.

•Can be mounted in standard 19-inch

(48.3-cm) rack. Uniquely molded, cast- aluminum front panel provides exceptional air circulation.

•Exclusive BCA ® (Balanced Current Amplifier) power design provides high efficiency for quiet, fan-free operation.

•Advanced protection circuitry guards against shorted outputs, open circuits, DC, mismatched loads, general overheating, high-frequency overloads and internal faults.

•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.

•Patented front-panel design.

•Backed by the industry’s ONLY three-year, no-fault, fully transferable warranty.
