A small microphone that clips to your clothing or can be worn on a lanyard. There may be slight variations in the design or model used, but the functionality and purpose remain the same.
- Keeps your hands free
- Ideal if you move around while teaching
- Smaller rooms may not have lapel microphones, while larger rooms may have multiple to accommodate more staff or speakers
Turning the Microphone On
- The microphone should turn on automatically when removed from the charging unit.
- If it does not turn on, look for a standby or power button on the top or side of the unit and press it.
Digital Display
Some microphone models include a digital display. Where present, this will show:
- Battery level – how much charge remains
- Connection strength – confirms the microphone is linked to the system
- Operating frequency – the channel the microphone is using
This information can be useful for quick checks before teaching, particularly in longer sessions or when using the microphone for recording.
If the display shows a low battery warning, return the microphone to the charging unit or replace the battery pack before starting.
Using the Microphone
- Use the slider at the top of the microphone to mute or unmute it.
- Use the clip to attach the microphone securely to your clothing.
- The microphone itself is located at the end of the cable and is very small.
Audio Connection (Mic/Line)
Mic/Line is the audio input used for microphones or other sound sources.
This is where the microphone cable plugs into the unit.
Status Light Guide
The status light shows whether the microphone is active, muted, or has a low battery:
- Green light – Microphone is on and active. Audio is being sent to the room and recording.
- Orange (amber) light – Microphone is on but muted or in standby. No audio is being sent.
- Red light – Microphone is muted or the battery is very low.
Quick check:
If the light is not green, check the mute button and battery before you start teaching.
Battery Pack
- The battery pack is located at the bottom of the unit.
- To remove it, press the two buttons on the side of the device.
- Return the microphone to the charging station after use.
