Here’s #5 in our ongoing series of tips and tricks for wireless systems, from Jeff Barnett, Sweetwater Sales Engineer and wireless expert:
The frequencies of multiple wireless systems must be carefully coordinated to avoid interference with each other. Simply having different frequencies is not enough. Usually, the best way to do this is to use wireless systems from the same manufacturer and series (Shure SLX, or Audio-Technica 3000 series, Sennheiser Evolution, etc.), and use frequencies that are already pre-coordinated not to interfere with each other.
If you are combining systems from different manufacturers or different series, consult an expert.
