IMPACT DCA 2.500 - D-Class Charger Amplifier
The IMPACT
on cabling!
The IMPACT DCA-2.500 is a lightweight 'transformer-less"direct-drive 2 x 500 W D-Class amplifier.
Housed in a 2U 19-inch rackhousing with integrated 4 Amp battery charger, makes the DCA-2.500 a resourceful and value-for-money device.

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.
