300W Four-Channel Class D Power Amplifier Respectively housed in 2 RU compact chassis, these Class D amplifiers offer High power in reduced size and weight. The combination Class D type amplification circuitry combined with SMPS (Switch mode Power Supplies) creates a high efficiency amplifier offering reduced power consumption and low heat dissipation. The DPA-Series offers both low impedance and High impedance outputs in one package Ideal for applications where high power and large quantity of long-line speaker installation is required such as Airports Arena, shopping malls, transportation stadiums or any large scale facilities. Class D Class D audio amplifier offer greater power efficiency over traditional amplifiers. Among their advantages is their reduced physical size and lower heat dissipation. They offer less than 1% THD, total harmonic distortion with an increased signal to noise ratio to 90db and a widened frequency response from 30Hz ~ 18 KHz Class D audio amplifier offers greater than 90% power efficiency over traditional amplifiers. SMPS – Switch mode power supply provides high efficiency and low weigh. Among their advantages is their reduced physical size and lower heat dissipation. The DPA series is fully equipped with a protection circuit against short circuit, overload, power and DC output. They offer less than 1% THD, total harmonic distortion with an increased signal to noise ratio to 90db and a widened frequency response from 30Hz ~ 18 KHz. Hi definition sound is achieved by using high impedance matching transformer and noise cancelling balance audio input. The total harmonic distortion is reduced to less than 0.1% THD, with a high signal to noise S /N ratio of over 100dB with optimum broadband frequency response of 65Hz ~ 20kHz. LCF (Low Cut Filter) A 2 position LOW CUT FILTER, at 65Hz, and 400Hz, helps to improve speech intelligibility and protects output from unwanted low frequencies.
