*If you are using two microphones they must be on the frequencies as indicated. If both mics are powered on with the same group/channel then neither mic will work.

Any of these microphones can be used in the listed spaces by matching the transmitted frequency on the mic to the receiver installed in the room. Programming instructions as well as the list of room frequencies are included in the bag with the microphone. The main purpose of these wireless mics are to provide sound reinforcement for individuals in the physical space itself. The AV system must be powered on from the touch panel for the mics to work. Speech levels are adjusted from the mic volume controls on the touch panel.

For rooms that have fixed cameras and microphones, the sound picked up by the mics will be added to the recording, or to the distant end of a live video conference using the mounted cameras.

Mic instructions:

Turn the microphone on with the switch at the top of the unit.
To set the frequency:
Press “Mode” button and press and hold until the channel number disappears.
Click the “Set” button until the desired group disappears.
Press “Mode” again and click “Set” until the correct channel appears.
Press “Mode” again to finalize settings.

Be sure to turn microphone power off after each use. Settings will be retained.

Standard 9 volt batteries may be loaded from the bottom of the unit as needed. One battery lasts for approximately 8 hours.

Wired Microphones

Wired microphones such as the Shure SM57 are also available for loan. These wired mics can be plugged into room podiums with auxiliary mic inputs or stand alone PA systems, mixers or speakers. Separate equipment such as a mixer or iRig Pro would be required for them to work with a desktop computer, laptop, or phone. They are durable, high quality and easy to use. The only drawback is that the user is limited in their ability to walk around since the mic is attached to a piece of equipment. The DMS has various lengths of mic cables available for loan with the wired microphones.

Panel Microphones

Panel microphones are available at the DMS. These mics come in sets of three, and are ideal if you are conducting a live panel discussion or interview with seated individuals. The “pickup pattern” of the mics allow for two people to share one microphone, so they can accommodate up to six panelists. These mics are stationary and do require cables. Most, but not all campus auditoriums support auxiliary microphones. Separate equipment such as a mixer or iRig Pro would be required for them to work with a desktop computer, laptop, or phone. Please inquire with DMS staff to see if the panel microphones can be used in your particular space.
