Guides
QLXD Microphones
QLXD microphones consist of a rechargeable battery pack and either a lapel or over-the-ear microphone. They can be found in a charging station on top of the instructor's desk or in a black drawer under the desk.
How to Operate
Turn on the microphone by toggling the power switch on the top of the battery pack to on
- A green light will appear next to the switch indicating the microphone is on.
- The battery pack is rechargeable and should not need replacement batteries. If the battery is dead, contact us
.
Clip the lapel microphone 6-8 inches directly below your mouth
Placing the microphone off to the side should be avoided to prevent audio from fading in and out as you move your head.
Place the battery back in a pocket or clip it to a belt or other article of clothing
Avoid placing it near a cellphone or other wireless device to prevent interference.
After Class
Turn off the microphone
Place the battery pack in the charging base
- The charging base is located on top of the instructor's desk or under the desk in an equipment rack.
- When fully inserted, the microphone will click into place and a red light will appear underneath the battery icon on the charging base.
- While it may look nice, the microphone cable should never be tightly wrapped around the battery pack or pinched. This can damage the microphone cable and cause shorts in the wire.

Ceiling Microphones
Ceiling microphones are found in most connect classrooms. They are used to record audio from the students/audience in a room and are typically controlled from the classroom touch panel.
How to Operate
Unmute and mute the ceiling microphone from the Classroom Touch Panel
Not all classrooms will the same colored indicator to show whether the microphones are muted. Some rooms have a red/green indicator, others have a gray/black indicator, and others do not have a colored indicator at all. When the "Mute" button is red or gray, the microphones are muted. When the button is green or black, the microphones should be unmuted. In cases where the room doesn't have a colored indicator, try pressing "Unmute." If the microphones are still not picking you up, try pressing "Unmute" and try again.
The following screenshots show the location of the mute button on the different touch panels:
After Class
Mute the ceiling microphones before leaving the room
Set Up Sound Reinforcement
Sound reinforcement amplifies a person's voice in a large room or space. It is only available in larger classrooms and can usually be controlled from the classroom touch panel.
How to Operate
Turn on the microphone and put it in position
Lapel microphones should be placed 6-8 inches directly below the mouth.
Turn on and configure sound reinforcement using the Classroom Touch Panel
The following screenshots show where to enable sound reinforcement on the different touch panels:
Some rooms provide the ability to adjust the sound reinforcement level. Follow these steps to ensure the level is set properly to prevent feedback:
- Turn the sound reinforcement level down to about 25%.
- Start counting or speaking into the microphone.
- While speaking, slowly turn up the sound reinforcement volume until you just barely hear the sound reinforcement.
- The level is now set.
