Tips to Improve Wireless System Performance

If you encounter interference or dropouts, try the following suggestions:

  • Choose a different receiver channel
  • Reposition the receiver so there is nothing obstructing a line of sight to the transmitter (including the audience)
  • Avoid placing transmitter and receiver where metal or other dense materials may be present
  • Move the receiver to the top of the equipment rack
  • Remove nearby sources of wireless interference, such as cell phones, two-way radios, computers, media players, Wi-Fi devices, and digital signal processors
  • Charge or replace the transmitter battery
  • Keep transmitters more than two meters (6 feet) apart
  • Keep the transmitter and receiver more than 5 meters (16 feet) apart
  • During sound check, mark trouble spots and ask presenters or performers to avoid those areas
