Setting Up Audio in Master Classrooms

The lavaliere microphone is intentionally provided to adequately project your voice throughout the space of the large theater-style classroom. It is also used to provide audio to your students on Zoom and to be heard by students wearing “listening assistance” headphones and hearing aids.

Step 1: Turning on the Mic

The first thing you need to do is to move the switch, located on top of the microphone, to the "On" position. 

Lavalier microphone set to the on position initiates a green light when batteries are charged

Step 2: Check the Battery Charge

Once the mic is on, check the battery meter on the transmitter to decide if new batteries are required. If the batteries are charged the small light about the on switch will emanate a green light.

If the batteries are not charged it will create a red light or no light.

If the batteries are not charged, replacement batteries can be found inside the microphone bag and you may change them as needed.

If there are no replacement batteries found inside the microphone bag and you need replacements, please call 978-3588 and let our staff know. A Campus Media Services staff member will bring batteries to your room as quickly as possible.

Step 3: Using the Microphone

To use the lavalier, or “lav”, microphone you need to clip it onto your shirt. The “lav” microphone should be clipped onto the shirt’s lapel as closely to the chin as possible, especially while wearing a mask.

An alternative is to clip the microphone toward the top of a lanyard placed around one’s neck.

Please do not clip the microphone below the third button on a button-up shirt or on the collar of a shirt.

Lastly, please note it is essential that you call for assistance while you are experiencing the problem so that we can best troubleshoot the error as it occurs.
