A, It used the advanced PWM (pulse width modulation)technology, amplifier operating efficiencies is up to 95%, only about 5% of the output energy changed into heat consumption. Reflecting faster response, higher damping factor, more advanced protection system,it has processed an excellent design of dissipate heat.

  B, The interior design of the power supply had used overvoltage and undervoltage protection, power supply over-current protection, temperature protection, limiting voltage protection, which provide a safe power supply system. And this product also has a perfect protection circuit system, comprehensive, safe, reliable, accurate, such as short-circuit protection, overload protection, DC protection and overheating protection etc.

  C, It has achieved the output power from 250w-1400w in the 1U height space.Classical PWM coding technique and more than 300KHZ switch frequency make this product in high quality.

  D, Amplifier makes in modular construction. Very low internal friction, lower static-load operating current, the efficiency of power amplifier has been greatly enhanced.

 E, Quite quiet, zero noise, excellent high frequency filtering makes the amplifier a very high S/n ratio( signal to noise ratio).

   F, Calm Audio digital power amplifier process superb technology, Lightweight body and the unique performace Patent.
