MA Lighting MA4023806 grandMA3 onPC Rack Unit for Fixed Install and Touring Rack

The grandMA3 onPC rack unit is engineered for lighting professionals who need a permanent, rack-mounted grandMA3 control node in fixed installations — theaters, broadcast and streaming studios, houses of worship, theme parks, and architectural lighting systems. With the grandMA3 onPC software pre-installed on a built-in MA motherboard, the unit is ready to operate as a standalone controller or as a reliable backup node within a larger grandMA3 network without requiring an external computer.

Supporting up to 4,096 real-time parameters, the rack unit fits into a 19" rack frame and provides dual DMX outputs, one DMX input, two RJ45 network connectors, and six USB ports for flexible system integration. Two external multi-touch screens can be connected alongside the internal multi-touch command screen, giving operators a full console-class interface without a dedicated console footprint. This makes it particularly effective for automated show systems triggered by external signals, where a compact, permanently installed controller is preferable to a full console or a tethered laptop wing setup.

For touring engineers and production companies, the rack unit also serves as a pre-programming station or a compact traveling node that fits standard rack cases. Across fixed and touring contexts alike, it delivers the familiar grandMA3 control environment — including the same software architecture used on full grandMA3 consoles — at a price point and form factor suited to distributed or backup control roles.
