The DPA4410/11 amplifiers have been specially designed to ensure durable performance and reliable operation of sound reinforcement systems with several independent loudspeaker lines.
The units are best suited for paging and pre-recorded message installations, alert systems, and for general music applications in industrial enterprises,
offices, multifunction halls, sport arenas, schools, churches, hotels, hospitals, super markets, cruise ships, and similar venues.
The DPA4410/11 amplifiers can either be operated on the AC mains or connected to an external 24 V battery power source.
Switching to battery operation is accomplished via an internal relay.
The four electronically balanced inputs are provided as XLR-type connectors (0 dBu). Also provided are routing switches, allowing input coupling.
Remote-starting the power amplifier is possible when it is operated on mains supply or on 24 VDC emergency power supply.
DPA4410 - 4x100w 4 Channel Power Amplifier has the same power output as the DPA4411 except it does not provide the remote control and monitoring functions.
The DPA4411 provides the following remote monitoring functions when used within a ProAnnounce system:
- Setting input levels on channels 1-4
- Reading level values of the audio level controls.
- Setting level offsets via virtual controllers.
- Mute function (via level controls).
- Remote control power operation ON/OFF.
- Battery operation remote control ON/OFF.
- Monitoring and fault message transmission of thermal overload warnings on the mains transformer or power output stages.
- Monitoring of the functioning of the power output stages 1 to 4 via pilot tone signal.
- Ground fault detection for loudspeaker lines.
Features
- Configurable as a 2x200, 2x100 & 1x200, or 4x100 amplifier
- Operation with 70V loudspeaker networks or 4/8 ohms low-impedance systems
- Outputs protected against idling, short-circuits, over-temp and load variations
- Integrated Remote Module for control and monitoring using the PROMATRIX Manager DPM 4000 (DPA4411 only)
- Routing switch for parallel operation of the amplifier’s inputs
- Integrated standby power supply
- Remote-Start function for mains and battery operation with inrush current limiter protection
- Power-on noise attenuation
- Status-LED indicators: operation (READY), STANDBY, thermal overload (PROTECT) and GROUND FAULT at the power outputs
- LED meters with a range from -13 dB to 0 dB plus CLIP indication
- Active, temperature-controlled ventilation
