Remote Presenters

Code4Lib will be using Zoom for remote presenters. In addition to the software, having the proper audio setup is key for a successful presentation.

  • Microphone: The best option is a headset or earbuds so a microphone is close to your mouth. Built-in laptop microphones are okay, but using them will make it harder for the audience to hear you.
  • Speaker: A headset or earbuds are required. Do not use your computer's built-in speakers. The echo cancellation software is designed for small rooms and cannot handle the delay caused by large ballrooms.

You can test your setup with a test Zoom call. Be sure your microphone and speakers are set correctly in Zoom. Also try sharing your screen on the test call so you understand how to start and stop screen sharing. The audience will see everything on your screen, so quit/disable/turn-off notifications that come from chat programs, email clients, and similar tools.

Plan to connect to the Zoom meeting 30 minutes before your talk to work out any connection or setup issues.
