Mute All Except Instructor
As an instructor, you have the option to require students to use PTT (push to talk) or to allow them to mute and unmute. In the classroom, click the gear menu and select “Students muted until [ctrl] pressed” or “Students can unmute at any time”.
As an instructor, you can always click the red microphone button to mute and unmute your own microphone..
When allowing students to unmute, you may experience unwanted noise or feedback from student microphones. To silence all other participants, click the gear menu and select “Mute All Except Instructor”.
