The GrandMA3 Processing Unit L is a 2RU rackmount engine for rental use that expands a grandMA3 system by 81,192 parameters and provides frame-synchronous parameter calculation across an MA-Net3 network. Designed for larger rigs and touring, the unit offers a compact, cost-effective way to add high-density parameter capacity, with an alternative Mode2 setting to expand existing grandMA2 systems by 40,096 parameters.

Key Features

• Large parameter expansion: 81,192 HTP/LTP parameters for grandMA3 systems, or 40,096 in Mode2 for grandMA2 compatibility.
• Frame-synchronous DMX: Built-in synchronization across MA-Net3 for consistent, low-latency output.
• Integrated touchscreen: Local overview and maintenance access, while all functions remain controllable from a grandMA3 session.
• Compact touring form factor: 2RU rackmount design, 482 x 372 x 87 mm, net weight approximately 5 kg.
• Outputs and connectivity: 8 DMX512-A outputs, 2 etherCON network ports, and powerCON TRUE1 0 power input. Additional frame-synchronous DMX outputs can be provided using grandMA3 xPort Nodes.

Use Cases

• Central parameter expansion for large festival or arena lighting systems, when the main consoles need additional channel capacity.
• Touring rigs where low weight and compact rack space are priorities, while maintaining frame-synchronous distribution via MA-Net3.
• Hybrid setups migrating from grandMA2 to grandMA3, using Mode2 to bridge parameter counts and maintain existing workflows.

Included with your rental

• GrandMA3 Processing Unit L (2RU) with integrated touchscreen
• Standard mains power cable compatible with local voltage
• Rackmount brackets and basic setup documentation
• Optional items typically available for hire: MA-Net cabling, DMX cables, grandMA3 xPort Nodes for extra DMX outputs, and on-site technical support. Please request these when booking.

Logistics and recommendations: For larger systems we recommend placing processing units centrally and distributing DMX outputs with grandMA3 xPort Nodes to minimize cable runs.
