2711Which microphone frequencies are used on campus?
If you want to use wireless microphones on campus, you will need to use an appropriate channel and frequency. Some frequencies are already reserved to eliminate interference.
- Reserved frequencies (login needed)
Two channels can be used for wireless microphones:
Channel 38
This is the usual channel for microphones. Usage is licensed by Ofcom so you should check with us to confirm an available frequency. Contact Steve Eastty or call for audiovisual support on extension 8022 (external 01273 678022).
Channel 70
This channel is unlicensed but out of courtesy, you should try not to interfere with frequencies that are already in use nearby (see the list of reserved frequencies for details).
