Professional power amplifier  
The appearance is simple and beautiful, the whole structure is safe and firm, and the image of professional technology of high grade product.
Machine with many groups of large capacity of the DC power supply system, make sure that the DC power supply voltage stability, make power amplifier thrust ability strong, all components are carefully selected, matching, elaborate, make sure the sound dynamic, structured, broad sound field, sound sweet.
The universal use of the chip SMD components, the shortest circuit transmission distance, eliminate interference, improve audio performance, while greatly reducing the artificial intervention, product reliability and long-term stability of any better guarantee.
The whole machine power supply part, regardless of the cost to set up the outstanding factor correction, completely eliminates the harmful harmonic current, satisfies the European and American electric industry regarding to use the electric appliance to the power factor request.
The series power amplifier is sensitive to the thermal management system, the unique line real-time monitoring to regulate the power amplifier temperature, when jeopardize the use of the product, without close circuit and by reducing the output power, when external cause is eliminated, the equipment will automatically restore to ensure equipment can work normally under high temperature and harsh environment.
The machine with intelligent protection system, to protect the sound reinforcement system stability, reliable work, make the whole project performed stable, peaceful smoothly.
Suitable for style KTV, bars, nightclubs, multi-function hall engineering series.
