Selecting Frequencies

When you buy or rent a wireless system, someone has to select an operating frequency (for fixed-frequency systems) or an operating frequency range (for frequency-agile systems). To do this job correctly, the dealer will need to know two things, and you will usually need to provide this information. They are:
  • The location or area where the wireless system will be used. Alternately, the channel numbers of the local TV stations can be provided. This allows the dealer to avoid TV frequencies when selecting frequencies.
  • The frequency, model and type of any other wireless microphone systems that will be in use at the same location. This allows the dealer to avoid using the same frequencies,frequencies that are too close together, or frequencies which interact. It also allows the dealer to determine if the maximum possible number of wireless systems will be exceeded. Existing equipment may have the frequency information inside the battery pack area.
