The DSP processor module and operating software are designed and produced by Germany, and Dante function gain, signal routing, frequency division, delay, voltage limit, FIR and other parameter debugging functions are optional. Using gallium nitride technology, high efficiency, low heat, reliable and durable, strong resistance to wear, clean tone, low distortion. Stable and reliable 2Ω drive capability, perfect for line array speaker system 80V-296V wide voltage operation, can adapt to the harsh power grid environment, low loss, energy saving and environmental protection, save operating costs. Using active PFC and soft switching technology, the power correction factor reaches up to 0.99, and the adaptability is strong. With ROSH, CE certification, national quality inspection report, energy conservation and environmental protection certification, can pass 3C tests. Using international high-end manufacturers of devices, first-class quality, advanced and reliable circuit, a variety of protection circuit complete, through strict reliability, environmental adaptability, user experience testing, extremely strict production process.
