KV Series power amplifiers use automated manufacturing processes such as SMD chip and laser scanning, using imported semiconductor components to greatly improve product reliability and consistency. Using the industry's most advanced frequency-adjusting soft-switching technology, the sound is majestic and powerful. With the adaptive dynamic supply of power supply, it achieves excellent power, real-time distortion limitation and real-time analysis of output voltage and current technology applications, so that the power can be more intelligent, more stable and reliable in the entire sound reinforcement system. The front panel display shows the volume and temperature of the AB channel. Perfect precision protection circuit, plus real-time online load detection, more effective protection of matching speakers. Suitable for halls, multimedia conference rooms, entertainment venues, etc.
