AtlasIED DMA401 1-Zone 400W Digital Mixer Amplifier
The DMA401 1-zone 400W digital mixer amplifier with Bluetooth is engineered for high-power commercial installations that require reliable performance, system expandability, and precise audio control. Factory-configured as a traditional mixer amplifier, it operates immediately out of the box without software, enabling fast and predictable installs. Its compact 1 RU half-rack chassis with included rack kit and intelligent cooling integrates seamlessly into professional racks and cabinets.
With 400 W of output power, the DMA401 supports 2Ω, 4Ω, 8Ω, and constant-voltage 25V, 70.7V, and 100V speaker systems, delivering clear and consistent sound for distributed audio, background music, and high-output PA applications. Expanded input options, including balanced mic/line, optical audio, and WTSD Bus, allow remote placement of sources and accessories. Onboard DSP and factory loudspeaker presets ensure optimized audio performance.
The DMA401 is built for scalable system design. The proprietary Link Bus allows linking with LMA Series amplifiers for multi-zone configurations, subwoofer integration, and centralized audio management. Energy-efficient standby operation, global auto-sensing power supply, Push Here Diagnostic speaker verification, and compatibility with DMA-V and DMA-VS wall controllers make the DMA401 a high-power, versatile, and reliable solution for professional integrators.
