Product Description
DS active professional power amplifier module board active speaker power amplifier module Using original imported electronic components, imported IR original field effect tube DS active power amplifier module series switching power supply power amplifiers can adapt to various harsh working environments, and the working voltage can be converted between 110V and 230V. Stable performance and sound quality open up a new world of more outstanding cost performance. It is an ideal power amplifier for professional multimedia installation projects. Main functions and features: 1. Balanced input and unbalanced input, with microphone input. 2. Use NTC thermistor to achieve soft start on boot, thereby protecting the speaker from the impact of booting. 3. All models have reliable multiple protections such as start-up delay, overload, over-temperature, and zero drift. 4. The working voltage can be manually switched from AC 110V to 230V. 5. Power saving and energy saving. The digital power amplifier can save up to 50% power compared with the traditional transformer power amplifier, and it is efficient and lightweight. 6. Use low-noise temperature-controlled fans to dissipate heat at close range. 7. Adopt the latest IR technology. 8. Adopt AD technology to design the circuit board to make the performance of the circuit board more stable
