Our company developed brand-new switch mode technology successfully in 2004. Combining with PWM, the independent load output pump filtration was greatly achieved. Comparing with the traditional analog amplifier, switch mode technology provides high efficiency, stronger power for speaker and sharply decrease in heat dissipation, moreover, high efficiency means that the equipment volume, weights and energy dissipation are greatly reduced. Operational efficiency of DA amplifier reaches 90%, while taking the rest 10% output energy dissipation as heat. Almost separating from output level the DS power is, however, the traditional amplifier could reach the perfect performance state under the condition of full rated output power only. Since the average power density of standard music occupies 40% only of the maximum output level, the traditional analog amplifier was easily produced 10 times (or more) heat than DA series with the same output power. Its time delay (phase shift) is about 60% of analog amplifier. What characteristics that DA digital amplifier has are low distortion, low noise, large dynamic range etc., with the incomparable clear acoustics, silent background and the superior LF effects that the traditional ones could not obtain.
