DIGITAL POWER AMPLIFIER
3 DPA-300T/300Q, DPA-300TO/300QO
Features Features
- High Performance Class-D Power PA Amplifier
High performance 3CH/4CH Class-D Power amplifiers produce 300W rated power each channel.
(DPA-300T/TO : 3CH, DPA-300Q/QO : 4CH)
- Emergency Power Back Up (24VDC) capability
The unit operates on a 24VDC battery power supply for emergency back up without UPS (DPA-TO/QO 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.
