Inter-M Americas DPA-430H 4-Channel 300W Power Amplifier

Inter-M Americas Inc's DPA-430H is a quad channel 300W amplifier70/100v capable of delivering a total 1200 watts of Power respectively housed in 1 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-430H offers 4 channels of High impedance 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.

DPA-430H are ideal for multi-zone 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.

The DPA-430H offers 4 channels of High impedance 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.
