Microphone, Wireless

Description:

Wireless microphones are available from Instructional Media Services (x83059) for use in most of our auditoriums and some larger classrooms. The rooms use the same microphone with different frequencies for each location. In some rooms, more than one microphone can be used if two frequencies are used. Both hand-held and clip-on microphones are available. Fixed-frequency wireless microphones are available for Chandler 230 and Grace 28.

If you are experiencing poor sound from a wireless microphone, first check the speech sound settings on the touch panel control (the technology system must be on for the microphone to work). Poor sound may indicate that the batteries may need to be replaced. Battery life is only between 3 and 6 hours of use. Cell phones or PDA devices have also been known to interfere with wireless microphones.
