Downloads
The DPA4140 amplifier has been specially designed to ensure durable performance and reliable operation of sound reinforcement systems with several independent loudspeaker lines. The unit is 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 DPA4140 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.
One input module is required for proper operation of the DPA4140. Two different versions are available. The NRS90222 is the remote control version which allows for full monitoring and control through the ProAnnounce Designer software. The other is the NRS90225 which provides only the XLR input connector and has no remote control functions available.
