Digital Amplifier DPA-130DC/230DC/430H
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 with an increased signal to noise ratio to 90db and a widened frequency response from 30Hz ~ 18 KHz.
High-Efficiency Digital Amplifier CLASS-D : CLASS-A/B Energy Saving Reduce power consumption Power Saving Battery (UPS) Power consumption 1800W Reduced Battery Consumption Reduced power consumption and low heat dissipation Cooling minimizes environment heat with saving in cooling requirements.
FEATURES 480W ANALOG AMP Compact and lightweight form factor It’s low profile design utilizing only 1RU of rack space. The DPA Series is packed with 4-channels of high power output. Each output will deliver 300 watts of power on 70 or 100v line. These ultra-light weight amplifiers offer reduced space and offer great advantages for system designers and engineers.
User friendly features LCF : A 2 position LOW CUT FILTER, at 65Hz, and 400Hz, helps to improve speech intelligibility and protects output from unwanted low frequencies. LED indicator : A 3 position LED VU meter indicates signal level plus a protect LED indicates amplifier status. A rear mounted remote power terminal allows for the amplifier to be switched on or off remotely, via a 3rd party controller or timer device.
The DPA-130DC and DPA-230DC are each a single channel 300W amplifier and a dual channel 600W amplifier respectably housed in 1 RU compact chassis. These models features a built in DC Battery backup circuit. 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.
