Features

Features

- High Power PA Amplifier

70V/100V Power amplifiers produce 300/600/900/1200W rated power.

- Emergency Power Back Up (DC24V) 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 (DC24V))

- Rated Output Power Via DC Backup Supply

Output power can be maintained as AC power when 24V DC 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.
