Setting the number of channels
You may find that in some circumstances you don’t need all the channels
available in your console. The system default is the maximum number of
channels the console can address. By reducing the channel count below
this maximum, you can significantly reduce processing time and free
console memory for other purposes.
If you plan to reduce the number of channels, note that when patching
fixtures you need one channel for every attribute in a fixture’s personality
(two channels for each 16-bit attribute). For example, a fixture’s
personality might require the assignment of 20 channels for the mix of
attributes and data types used by that fixture. If you patched five of those
fixtures, your console would need to provide 100 channels.
Follow these steps to set the channel count for your console:
