Though audiovisual tech advances have allowed for better concert staging than ever before, they aren’t without their fair share of challenges. Wireless mics, in particular, can present a new set of issues that stage crews may not have dealt with in the past. The following are some of the most common show-disrupting mistakes made with wireless mics as well as what you can do to avoid them.
Top 3 Wireless Mics Miscues
1. Battery Blues
The very nature of wireless mics means they depend on batteries to function properly throughout a concert. When inexpensive batteries are used, however, insufficient voltage can result in distortion and signal drops. Use rechargeable batteries that provide sufficient output voltage to match the transmitter’s requirements. Don’t forget to charge batteries between shows!
2. Signal Blocking
A wireless signal can be easily blocked by other objects. To avoid this problem, a clear line of sight should be maintained between all transmitters and receivers used for the concert. Antennas should be kept higher than the audience and any other objects that might block the signal. Don’t fold or coil the transmitter’s antenna to keep the signal strong, and place the receiving antennas as close to the transmitter as possible.
3. Frequency Issues
The transmitters and antennas used by wireless mics must use compatible frequencies, but that’s not all — they also need to avoid the frequencies used by any TV station located within a 50- to 60-mile radius. Keep in mind that TV frequencies vary from place to place, so touring groups often need to adjust their frequencies for each show.
