Features:
1. High efficiency
Amplifier efficiency reach up to 80% -90%, the power consumption can be reduced more than 60% compared with the analog amplifier .
2. Stable and reliable
Optimized design with high performance and low heating can easily meet the demanding fixed installation requirements of ultra-long emergency broadcast. And we have done lots of stability testing to ensure long life operation.
3. Perfect protection circuit
DA modular digital power amplifier provides a full range of protection circuits to cope with over-current, short circuit, abnormal DC voltage output and heat sink temperature rise caused by overload.
4. Lightweight and space saving design
The lightweight make the installation easy, compact 1U height can be significant saving in rack space. It also save the transportation and warehousing costs.
5. Independent power supply for each amplifier module
Each channel amplifier module has their own power supply module. Other channel can not be affected when some channel has faults. You can use one or more channel as a backup amplifier. Also it can reduce the maintenance cost because of the modular circuit design.
6. Perfect sound quality
∑ vector amplification make the sound quality perfect and can protect the speaker for longer life.
7. Convenient front panel volume control and status indicator: power, output signal, clip and protect.
Application:
Superior DA series constant voltage digital power amplifier can be widely used in various public address needs, The modular design of the whole series enables this series to create more flexible application requirements:
You can use a stand-alone channel, two-channel, four-channel amplifier; You can also use the two channels as one master and one standby; Even you can use the four channels as three masters and one backup, and two masters and two standbys.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.
