Output Limitations of Paradigm Architectural Control Processor (P-ACP)


  • The Paradigm Architectural Control Processor (P-ACP) is limited to 1024 unique channels or parameters. Each channel can be patched to multiple addresses, but only counts as one channel toward this limit. You can assign up to 12 sACN universes to each P-ACP, as long as patching is limited to the 1024 unique channels.

  • The P-ACP output count cannot be upgraded. 


Output addresses and unique channel patch are two different things. Each parameter of a fixture counts as a unique channel. That fixture, however, can be patched to multiple addresses without counting against the unique channel patch count. For example, if you have an RGB fixture that would count as 3 unique channels of the 1024. If the fixture is patched to 30 addresses in Universe 1 you are still only using 3 unique channels but 30 addresses would get applied to the output address limit per processor which is 12 universes (6144 addresses). This is further illustrated by the System Estimator screenshot below.
