KV1200W 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.

Please read following before buying , It’s important ! Thanks for your time .
Impedance Matching :D4 amplifier suitable for impedance 4ohms or above .It's ok to shortly work with 2ohm impedance but we don't suggest to work under 2ohms. It's harmful to amplifier.
How to match this amplifier with your speaker ?Under certain impedance conditions, amplifier's power should be 1.5-2 times that of the speaker. So D4 suitable for the speaker rated power around 600-800W.
Idea Collocation : D4 match with Single 18inch/ Double 15inch professional PA speaker
What amplifier transistor do you use ?We use MOSFET transistor,2pcs transistor per channel .Sound is very clear and strong !
