Voice Alarm & Voice Evacuation Systems

The EN54-16 and EN54-4 standard certified, lightweight DCA-2.500 D-Class amplifier provides powerful audio amplification. It delivers 2 x 500 W outputs and is housed in a 2U 19-inch rackhousing. Multiple DCA-2.500 amplifiers can be stacked together sharing a single battery pack, providing back-up power and collective recharging capabilities. 
The amplifier has been designed along ‘modern-art’ lines and features a transformer-less design with not only a direct 100 
V output for distributed loudspeaker systems, but also drives into a low-impedance source from 8ohm and up. With cutting-edge design, the DCA-2.500 sets a standard for the most demanding projects with demanding audio architecture. 
The DCA-2.500 boasts a channel independant, dual voltage mains supply in combination with a secondary 24 VDC battery 
backup, crucial for ultimate reliability and durability in a VACIE system. 
Each DCA-2.500 is equipped with a powerful 4A battery charger capable of charging into a single 100Ah battery set. 
A Master/Slave system architecture, dictated by the AMP- LINK, regulates the battery-cluster charging procedure and status control. This way a single, larger battery pack can be shared with multiple amplifiers.  
The AMP-LINK module offers a local analogue AUX entry for local music playback into channel A and/or B. This allows for 
third party Commercial use integration, hence still complying to the VACIE standards.
