1. Product Function Description:
1. High-grade aluminum 1U black oxidized brushed panel, beautiful and elegant;
2. All internal PCBs use double-sided SMT patch circuits, which make the performance more stable and reliable;
3. Adopting international advanced Class D digital power amplifier circuit, it has the characteristics of high efficiency and energy saving;
4. The output adopts an isolated audio transformer to effectively enhance the load capacity and make it more stable and reliable;
5. Using RCA lotus socket, no need for conversion plug, the interface is more flexible;
6. Equipped with 70V/100V adaptive constant voltage output and 4-8Ω constant resistance output;
7. The output volume is adjustable, and the potentiometer adopts a fully sealed dust-proof process, which is permanently dust-proof and has no noise during adjustment;
8.4-unit LED display, easy to observe the working status;
9. It has complete output short circuit protection, DC protection, overload protection, over-temperature protection and other functions;
10. The cooling fan adopts automatic speed regulation design. The lower the temperature, the slower the speed, which effectively reduces the working noise during standby;
