MA Lighting MA4010508 grandMA3 Processing Unit Rack Module | XL

The grandMA3 processing unit family is engineered for lighting programmers and system integrators who need to scale parameter capacity beyond what a single console or onPC node can provide. Running within the MA-Net3 network environment, these units perform frame-synchronous calculation of fixture parameters, ensuring that every DMX value across the system is output in precise temporal alignment — a critical requirement on large touring rigs and complex installed systems where parameter counts push into the tens of thousands.

Each unit is built into a 2RU rack chassis, making them a practical fit for touring racks, dedicated equipment rooms, and permanent installs alike. The eight onboard DMX outputs deliver frame-synchronous data directly, and the architecture is designed to scale further through grandMA3 xPort Nodes distributed throughout the venue or rig. This centralized processing approach keeps the heavy calculation load off the console and allows DMX distribution to reach practically any system size.

An integrated touchscreen gives technicians direct access to system status and maintenance functions without pulling up a remote session — an efficiency gain when units are deployed in dedicated equipment racks away from the front-of-house position. For production managers running grandMA3 sessions across multiple nodes, this visibility reduces troubleshooting time during load-in and system checks.
