MA3 Processing Unit

The grandMA3 Processing Unit is the quick and easy way to add thousands of parameters to a MA3 or MA2 console.


Expanding the grandMA3 system is simple with addition of the MA3 processing unit. The MA3 processing unit L (Large) expands the system by 8,192 parameters and offers frame-synchronous calculation of the parameters. Designed for larger systems, the L model offers a more cost effective and compact solution for parameter expansion. Additionally, the processing unit is backwards compatible so a you can expand existing grandMA2 systems by 4,096 parameters.

The MA3 processing units are designed for rack mounting and all models are only 2 Rack spaces, allowing for efficient touring solutions. Each model is equipped with 8 DMX outputs, a True1 input, and 3 USB ports. Additional DMX outputs are available with the addition of a Pathport Octo Node or Pathport Quattro Node.

The MA3 processing unit provides a system overview on an integrated touchscreen. This easy access to important functions allows for best maintenance if installed in a dedicated rack where every function can be monitored from the grandMA session. We offer data processing racks that custom built for your specific needs with switches, backup power supplies, nodes, and more.
