Wireless really has nothing to do with actual audio, which is one of the reasons many audio engineers struggle with the concept. But it is used almost everywhere – TV, theatre, major sporting events – where there is no tolerance for failure. It all has to work. The numbers soon add up when each person is a mic and and IEMS, which are then doubled up for redundancy. Radio spectrum is a finite resource, so managing the frequencies within a fairly narrow bandwidth becomes really important. If you’re looking for a sound engineering job, consider getting to grips with wireless technology – it is so widely used these days you will always have work! Filmed at PLASA Focus, Leeds, 2014.
Wireless technology is widely used, so live sound engineers who understand RF are in big demand. This fantastic talk demystifies the subject.
