Energy efficient 

Amplifier efficiency can reach 80% -90%, compared with the analog amplifier energy consumption can be reduced by more than 60%.

Stable and reliable

Optimal design of high-performance low fever can easily tackle the most demanding ultra-long emergency radio fixed installation requirements, 

DA series amplifier has passed a number of rigorous tests to ensure durability over a long period of work.

Perfect protection circuit
DA digital amplifier provides a full range of protection circuitry for generating the excess current overload, short circuit, DC output voltage is abnormal, and the heat sink temperature rising.

Lightweight, highly integrated design

Lightweight design makes installation easy, compact 1U height can be significant savings in rack space. It also saves the transportation and warehousing costs.

Independent power supply

On the power of each channel individually designed, resulting in a channel fails, it will not affect the normal operation of the other channels. Similarly, you can use one channel as a spare amplifier to use.


Excellent DA series constant voltage digital power amplifier can be widely used in various public address needs, The modular design makes the entire series to this series can offer more flexible applications: 

You can use a stand-alone channel, two-channel, four-channel amplifier, Also you can put the two channels as a main one to use, Even put a four-channel as the three main equipment, two primary, two standby to use. 

These features make the DA series amplifier suitable for the needs of a variety of large-scale projects, such as exhibition halls, stadiums, stations, airports, theme parks, buildings, factories, schools, hotels and so on.
