CROWNKVS 300

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.
