Summary
Most rooms in LSA classrooms are equipped with at least one microphone. These are used to reinforce the speaker's voice to be heard in the room, by remote participants during Zoom calls, or to capture the voice on recorded lectures. This article provides basic information and troubleshooting advice.
Body
Q: How do I turn the microphone on or off?
For a beltpack lavalier or lapel microphone:
- On the top of the pack, adjacent to the antenna and the microphone port, there is a small on/off switch.
- A green light indicates that the microphone is on.
The hand-held microphone has a black on-off switch directly beneath its display window.
Issue: There is no sound coming out of the room speakers, even though the microphone is on.
- Call Tech Services (734-615-0100) #1 to speak to a Technical Assistance Group representative.
- Any additional information TAG may need for resolving a microphone issue may be found at the receiver, mounted in plain view on most podiums.
- Data displayed on its screen (and in the microphone's display window) will prove useful in helping you convey information to the TAG representative.
- Some receivers handle one microphone, others accommodate two, or more.
Q: I’m done using my microphone for class. Where should I put it?
- Please return the microphone to the charging station on the podium for the next instructor.
- Place the microphone with the display screen facing toward you as you drop the microphone into the charging port.
- You will feel the pack click into place with little resistance.
- Look for a set of spokes at the bottom of each of the two charging ports.
- These spokes should line up with the brass contacts located on the back of the microphone, at the bottom.
- If you are the last instructor of the day, it is important to ensure that the microphone is charging overnight.
- A solid red light on the charger indicates that the microphone is charging. Green indicates that the microphone is fully charged.
- A white light may indicate that the microphone is still on. Be sure to switch off the microphone before placing in the charging bay.
- A blinking yellow light could indicate that a microphone is not properly seated in the charging bay.
- Sometimes the blinking yellow light symptom is traceable to the power supply cord, which may have worked loose and needs to be re-seated.
- To re-seat the connection, unscrew the threaded locking ring, unplug and reconnect, then tighten the ring.
- Recharging stations also accommodate single batteries.
- Like the microphones, these must be properly seated in order to fully charge.
WARNING:
- Never load regular alkaline batteries into microphones normally powered by rechargeable batteries.
- Alkaline batteries are sometimes found in or near the classroom podium.
- These are used in Catchbox Microphones and other devices.
- Microphones mistakenly loaded with alkaline batteries and placed in charging bays could overheat and damage the equipment.
