Hello, Does anyone have an opinion on whether it's better to let units such as Shure's ULX line "find" and self coordinate their own frequencies or whether it's better to use Workbench (or some other package) and calculate these frequencies then plug them in. I would be interested to know if there is a difference in the results - or, what the advantages / disadvantages may be. I use an RF spectrum analyzer and input that data into Workbench. I run some area scans, drop those into Workbench, then, I calculate frequencies and drop those into the units. And, I test. Usually, this works very well for me. But, I've run into a couple major issues recently that have me questioning whether this process is working the best it can and wondering whether I might get to a workable end result faster if I just use the finder functions on the units. Another question I have is if a setup is comprised of different offerings from different manufacturers (Shure, Sennheiser, AT) and different levels of frequency-agility, then is there really any option BUT to use software like Workbench to coordinate these units? It just seems to me to be way too complicated to use the unit functions, but I could be wrong on that.
