grandMA3 full-size
The largest grandMA3 control surface, rated at 20,480 parameters with six DMX outputs and three network ports on the back. The desk most large touring and arena rigs are built around.
Protocols it speaks
| Protocol | Direction | Notes |
|---|---|---|
| dmx512 | out | Six DMX512-A outputs on 5-pin XLR female. |
| dmx512 | in | One DMX512-A input on 5-pin XLR male. |
| sacn | bidirectional | One of the two Ethernet DMX protocols grandMA3 supports for sending and receiving. |
| art-net | bidirectional | Art-Net revision 1.4db. Sent as unicast until more than five receivers subscribe to a universe. |
| osc | bidirectional | |
| psn | in | |
| ndi | bidirectional |
Connectors
- 6x XLR5F DMX512-A out

What to watch for
44 kg and 1256 mm wide before you add monitors. Check the FOH riser and the door it has to go through, not just the truck pack.
Only sACN and Art-Net are available for network DMX. A venue standardised on Pathport or ShowNet needs a gateway in the path.
Art-Net is unicast by default until more than five receivers want the same universe. A node that appears late in the patch can silently change the traffic pattern on the network.
Six physical DMX outputs is nowhere near 20,480 parameters. Anything past a handful of universes leaves the desk over the network, so the switch is part of the control system.
