The KVS Series represent Crown's professional-grade power amplifiers designed for fixed installation applications, with four models available: KVS300, KVS500, KVS700 and KVS1000.

KVS Series power amplifiers use switching power supplies that offer high stability and a high-speed response. When compared with similar products, the KVS Series have reduced weight and heat generation, with significantly improved power efficiency and operating stability. In addition, the integrated protection circuit can effectively avoid overvoltage, undervoltage, overcurrent, overheating and other issues and ensures that the equipment can operate even in the most demanding application environments.
