Field notes
The index has a search field and groups entries across audio, lighting, video, network, power, and several show-related categories. Some descriptions state important assumptions: speaker coverage uses a free-field estimate, while SPL drop-off compares idealized propagation models. The page also lists a DMX patch-list export and wireless frequency-spacing checks; it says the RTA/feedback tool works offline once loaded.
