Features: ? Because of adopting class-H type circuit, make the efficiency of amplifier up to 80%. ? the power thoroughfare can offer enough working voltage and floating electric current. The wqy of power supply is analogy and digital, it is undoubtedly a kind of brand-new, high-efficient and digitization amplifier. ? Advanced intelligence limiter provides the flexibility of varied loads within 2-16?, and versatile input sensitivity without distortion. ? Also made music more clean and protect the expensive loudspeaker at the same time. ? EMC and RF wave filter make cleaning for the power and provide super high speed switch power supply, twinkling response is extremely good, special wide frequency, middle and high-frequency is round and smooth, stronger punch in power made you a mind-blowing sense even. ? more light weight, it?s more convenient for use in varied locations.
