Product Characteristics
High performance multi-channel power amplifier, adopting the latest overall optimization technology and advanced circuit design, is meticulously improved and designed; The power start adopts an automatic detection switch delay circuit; The system can operate normally and efficiently. High performance ring transformer is used for independent power supply to minimize Intermodulation and noise. By significantly reducing AC power consumption and heat generation, the operating cost is ultimately reduced It is a new generation of excellent professional power amplifier. The unique power output circuit makes the dynamic range of voltage larger. The independent large capacity ring transformer makes the output power more powerful and the harmonic distortion and Intermodulation less. The power output transistor works in a safer area, greatly improving the reliability and durability of the machine. And equipped with a low-noise two speed fan controlled by high-speed and low-speed thermal sensors.
All protection functions are available, including short circuit, overheating, overload, overcurrent, output DC, soft start, current fuse protection, transformer overheating protection
