Functional characteristics 1. Industrial solid aluminum panel, equipped with multi-functional LCD screen, signal dynamic display, temperature display, voltage display, so that the working condition of the product can be clearly seen. 2. Boot soft start, to prevent the power grid to absorb large current, interference with other electrical equipment. 3. Intelligent control forced heat dissipation design, fan noise is small, stepless wind speed, intelligent constant temperature, high heat dissipation efficiency. 4. Two-channel power amplifier has three input sensitivity options, easily accept a wide range of signal source input. Can switch ultra-high frequency signal switch, bridge function indicator. 5. Perfect and reliable safety protection measures and working status indicators (short circuit, overload, DC and overheating protection), so that users can use at ease. 6. Intelligent clipper limiter, control power module and speaker system work within the safe range. 7. Standard XLR+TRS1/4 "composite input interface, simple interface is more convenient for different user needs. 8. High quality transformer and low resistance and large capacity electrolytic filter, to ensure that large dynamic work can cope with freely. 9. Adapt to different occasions, optional stereo or bridge working mode. 10. Input grounding pin grounding and suspension control.
