Product Features:

1: The power factor correction technology of digital power amplifiers improves the performance of power amplifiers, reduces the consumption of power supply current, and consumes one-third of the power of analog power amplifiers of the same power, which meets the requirements of green environmental protection.

2: With a high energy conversion rate of up to 95% and low heat generation, the small 1U space can stably deliver powerful power output.

3: The working state is in the on/off state, and there will be no crossover distortion. The overall distortion is small and the restoration degree is high.

4: Good transient response, good dynamic characteristics, extremely strong explosion sensation, deep and powerful low frequency, extremely low diving depth, transparent, clear and pleasant mid to high frequency.

5: Strong load capacity, capable of handling low impedance loads. The impedance of the load has little impact on the power conversion efficiency, and the internal resistance is small, so there is no matching problem with the speaker.

6: Built in precise amplitude limiting circuit, regardless of the load impedance, the circuit can detect whether the output is peak shaving and provide restrictions in advance, making system operation safer.

7； Soft start protection, overload protection, overheating protection, DC protection, short circuit protection, input peak voltage line, output intelligent clipping protection.

Suitable for: conference rooms, lecture halls, multifunctional lecture halls, etc.
