The AtlasIED DMA101 is purpose-built for straightforward, single-zone commercial audio installations where reliability and fast deployment are essential.

Factory-configured to operate as a traditional mixer amplifier right out of the box, the DMA101 requires no mobile app or programming for basic operation. Clearly labeled front-panel controls allow integrators to complete installations quickly while minimizing end-user confusion and service callbacks.

For expanded configuration, the DMA Control App (iOS and Android) connects via Bluetooth Low Energy, enabling advanced setup features including zone presets, input management, and scalable system configuration without direct rack access.

Flexible Installation & Operation

The DMA101 supports both low-impedance and constant-voltage speaker systems, allowing integrators to deploy it in a wide range of small commercial environments.

An auto-sensing, switch-mode power supply ensures stable operation across global power conditions while maintaining high efficiency.

The included rack kit and half-rack form factor make it ideal for space-constrained racks and cabinets. 

Smart Control & Expansion

When basic operation is sufficient, the DMA101 functions like a traditional mixer amplifier.

When expanded control is needed, the DMA Control App provides:

• Zone preset configuration

• Input management

• DSP adjustment

• Future system scalability

The Zone Link output allows integration with an LMA Series amplifier for expanded power or secondary zone applications.

Built-In Diagnostics

Push Here Diagnostic (PHD) enables quick verification of speaker wiring and load conditions during commissioning, helping installers confirm system readiness before leaving the site.

Support for remote wall-mounted level and source controllers further enhances usability in installed environments. 

Ideal Applications

• Restaurants & cafés

• Small retail background/foreground music

• Presentation rooms

• K–12 and higher education facilities

• Small commercial single-zone audio systems
