technology to improve the performance, reduce the consumption of current, the power consumption is one-third of the analog power amplifier with the same power, which meets the requirements of green environmental protection.<\/li><li>Special designed mold with distinctive appearance, with 2.0-inch TFT full-vision (IPS) colorful display, show the volume\/temperature\/connection mode status of each channel, convenient for local diagnosis in time.<\/li><li>Equipped with display to show the gain and internal temperature of each channel at the same time, which is easy to debug and monitor.<\/li><li>Up to 95% energy conversion rate, low heat generation, stable and strong power output.<\/li><li>Digital signal amplification is used to make the phase of the output signal and the input signal exactly same, there is no relative change of high frequency, intermediate frequency and low frequency, and the phase shift is zero, so the sound image positioning is accurate.<\/li><li>There will be no crossover distortion, no zero-crossing distortion, and high degree of restoration when the amplifier is in the switching state.<\/li><li>Good transient response, good dynamic characteristics, strong explosive feeling, thick and powerful low frequency, clear and pleasant mid-high frequency.<\/li><li>Strong load capacity can be connected to low impedance load, more convenient to match.<\/li><li>Built-in precise limiter circuit, regardless of the load impedance, the circuit can detect whether the output is clipping and limit it in advance, making the system
