Overview

The DPA-O Series is a amplifier operate in 4 – 8 ohm/ 70V/ 100V modes and are capable of delivering a total 

1200 watts of Power. 

Respectively housed in 2 RU compact chassis, these Class D amplifiers offer High power in reduced size and weight.


The combination Class D topology amplification circuitry combined with SMPS (Switch mode Power Supplies) creates 

a high efficiency amplifier offering reduced power consumption and low heat dissipation. 


The DPA-O 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.

Feature

- High Performance Class-D Power PA Amplifier

  High performance Class-D Power amplifiers produce 300/600/900/1200W rated power each channel.

 

- Emergency Power Back Up (24VDC) Capability

  The unit operates on a DC24 V battery power supply for emergency back up without UPS (DPA-SO models 

  are not included with emergency power back Up (24VDC))

 

- Rated Output Power Via DC Backup Supply

  Output power can be maintained as AC power when 24VDC power supplied.

 

- Advanced Power Circuitry Design

  The combination Class-D type amplification circuitry combined with SMPS creates a high efficiency amplifier

  offering reduced power consumption and low heat dissipation and weight.

 

- High Quality Sound Design

  The total harmonic distortion is reduced to less than 0.03% THD, with a high signal to noise S /N ratio of over 103dB

 

- Advanced Protection Circuitry

  Advanced protection circuitry guards against overheating, shorted outputs, DC output, overloads and

  mismatched power

 

- A Variety of operation Indicators

  Signal, -10dB signal level, Clip, Protection and system power (AC, DC, STBY) indicators

 

- Balanced Input

  This connection is used to ensure the lowest noise operation which eliminates the common noise from the cable.

 

- Remote Power ON/OFF

  The remote power allows the amplifier to be turned on or off from a distance or other device via dry contact closure.

 

- PRIORITY Input

  PGM is interrupted and over ridden by the Priority input, when a contact closure is received on the PRI select terminal. 

  This is Ideal for Emergency message broadcasting applications.
