Product Features

■ High Performance Class-D Power PA Amplifier

    High performance 2CH Class-D Power amplifiers produce 300/600W rated power each channel.

■ Emergency Power Back Up (24VDC) capability

    The unit operates on a 24VDC battery power supply for emergency back up without UPS (DPA-DO 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.
