Expanding the grandMA3 system is simple with addition of grandMA3 processing units! The grandMA3 processing unit L expands the system by 8 192 parameters and offers frame-synchronous calculation of the parameters within the MA-Net3 environment. Designed for larger systems, the L model offers a more cost effective and compact solution for parameter expansion. Additionally, the grandMA3 processing unit L offers a Mode2 to expand existing grandMA2 systems by 4 096 parameters.

The grandMA3 processing units are designed for rack mounting and all models are only 2RU, allowing for efficient touring solutions. Each model is equipped with 8 DMX outputs for frame-synchronous DMX output throughout the network. Additional frame-synchronous DMX outputs are available with the addition of grandMA3 xPort Nodes. grandMA3 processing units offer a perfect system overview on the integrated touchscreen. This easy access to important functions allows for best maintenance if installed in a dedicated rack whilst every function can be monitored from the grandMA3 session. For larger systems it is suggested to keep the grandMA3 processing units in a centralized position for parameter expansion and to use grandMA3 xPort Nodes to distribute and output the frame-synchronous DMX data.
