Two-channel, 450W @ 4Ω Power Amplifier


The KVS Series of power amplifiers from Crown represent a new era in affordable, quality power amplification. The line consists of four models in a uniform, rugged chassis, incorporating the best of reliable design principles and innovative features. Modern power amplifiers are sophisticated pieces of engineering products, which are capable of producing extremely high power. If we need to have them providing years of reliable service, we must treat them seriously and have them correctly installed. In addition, KVS Series amplifiers include a number of features which require some explanation before they can be used to their maximum advantage. Please take time to study this manual so that you can obtain the best possible service from your amplifier.


·       Simple, reliable design incorporates many popular features.

·       Housed in a rugged, all-steel 2U chassis.

·       Efficient forced-air fans prevent excessive thermal buildup.

·       Electronically balanced XLR inputs. Touch-proof binding post and Speakon® outputs.

·       Features precision detented level controls, power switch, power LED, and six LEDs which indicate signal, clip, and fault for each channel.
