Overview and characteristics of DM series professional audio power amplifiers:
DM series products are our latest professional class D switching power amplifier, using the PFC+LLC high-precision professional power amplifier switching power supply unique technology, and the application of advanced class D digital electronic amplifying circuit, and release the hi-fi level sound field listening sense.
This series product is the vehicle (class AB and class H) all the work efficiency characteristics of the power amplifier and protective functions such as overload limiter/over-current protection, temperature control automatic protection/DC protection/RF/overheat protection circuit design, and start up delay launch large current shock protection a no less outside, maximum optimization is to reduce the weight of the device itself, increase equipment installation, handling and transportation convenient easy to move，It is widely used in language sound field environment system.
