PRODUCT DESCRIPTION


4通道功放产品介绍.png

· Super-large switching power amplifier;

· Automatic limiting output, short circuit, overload, over temperature, startup delay and other protection functions;

· The amplifier is equipped with a delayed start system to protect the speaker box from demage due to impact;

· Tandard frame structure;

· The power amplifier part of the switching power supply part has a separate cooling system;

· The cooling fan is controlled by advanced infinitely variable speed circuit;

· 1U design, light body, easy to carry and install;



4通道功放产品介绍-2.png

· 4 channel power amplifier, which can be used in meeting rooms, multi-function hall and entertainment places of the hotel, matched with imported speakers and imported unit speakers, easy to listen and sing; 

· Small volume, lightweight, supporting 1U cabinet, beautiful and convenient installation; 

· linear stabilized voltage shape power supply, ultra-high efficiency, high stability, single power supply per channel, super output current; 

· High-efficiency digital power amplifier circuit, with higher efficiency, wider frequency response, smaller distortion and finer sound; 

· Super power-saving. In the same environment with the same power within a day, the dissipated power is 1/3 of the power amplifier of flexible AB type transformer; 

· Internal application of components with high durability; all core components are imported from the United States and Europe with guaranteed performance; 

· International procurement of raw materials, industrial automation and environmental protection production, production process consistency and quality reliability.
