AtlasIED DMA201 Digital Mixer Amplifier – 200W Smart Integration Solution

The AtlasIED DMA201 is a professional 200-watt digital mixer amplifier engineered for commercial integrators requiring flexible system configuration, intelligent audio processing, and reliable performance without unnecessary complexity. Designed to bridge the gap between traditional mixer amplifiers and advanced DSP platforms, the DMA201 operates immediately as a factory-configured mixer amplifier out of the box—no software, no programming, no delays—while offering powerful customization capabilities through the optional DMA Control mobile app when deeper system optimization is needed.

Built for medium-sized commercial and institutional applications including restaurants, retail environments, corporate presentation rooms, educational facilities, and houses of worship, the DMA201 delivers 200 watts of clean Class D amplification with multi-impedance capability supporting 2Ω, 4Ω, 8Ω, 25V, 70.7V, and 100V distributed systems. This exceptional versatility enables integrators to deploy the same amplifier platform across diverse applications, reducing inventory complexity and streamlining installations.

The DMA201's comprehensive input section features four versatile inputs (three mic/line with balanced XLR/unbalanced RCA options plus optical digital audio) and remote WTSD Bus connectivity for distributed source placement using standard Cat5/6 cabling. This architecture enables clean, cost-effective system designs where audio sources and wireless accessories can be positioned remotely from the equipment rack—ideal for restaurants requiring Bluetooth streaming at host stands, retail spaces with distributed music sources, or educational facilities with multiple program inputs.

System scalability is achieved through the proprietary Link Bus connection, allowing the DMA201 to pair with AtlasIED LMA Series amplifiers for seamless two-zone expansion with centralized control. This unique capability enables systems to grow organically from single-zone installations to sophisticated multi-zone environments without replacing existing infrastructure or introducing control system complexity.

Engineered for energy efficiency and silent operation, the DMA201 features global auto-sensing power supply (100-240V AC), Energy Star–compliant 1-watt standby mode, and intelligent fan control that remains inaudible during typical operation. Integrated speaker line diagnostics provide real-time monitoring of connected speakers, while compatibility with AtlasIED remote wall controllers (DMA-V, DMA-VS) enables intuitive local control without additional control processors.

The compact half-rack form factor (rack kit included) conserves valuable equipment space, while the robust metal construction and professional-grade components ensure long-term reliability in continuous-duty commercial applications. Factory-configured DSP presets for common applications (1-zone, 2-zone, zone expansion, subwoofer) accelerate commissioning, while onboard loudspeaker presets for AtlasIED speakers optimize system performance with minimal tuning.

Backed by AtlasIED's decades of commercial audio expertise and North American support network, the DMA201 represents the ideal solution for integrators requiring professional performance, system flexibility, and installation efficiency without the complexity and cost of full-scale DSP platforms.
