The DPA4411 amplifier has been specially designed to ensure durable performance and reliable operation of sound reinforcement systems with several independent loudspeaker lines. This unit is best suited for paging and pre-recorded message installations alert systems and for general music applications in industrial enterprises offices multi-function halls sport arenas schools churches hotels hospitals super markets cruise ships and similar venues. The DPA4411 amplifier 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 4411 also provides extensive system control and monitor functions which support level control a variety of fault monitors and signal routing. 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.
