Meeting and webinar presenters managing their audio with hardware and software-based audio mixers can also manage which audio channels are used by the Zoom desktop client. This article guides them through enabling the setting and managing the detected channels.

Prerequisites for using multiple audio channels

• Zoom desktop client
  • Windows: 5.13.5 or higher
  • macOS: 5.13.5 or higher
• A input device with 3 or more input channels detected
  Note: The device must be recognized by your Windows or macOS in order for Zoom to detect the device as well.

3. Click Audio .
4. In the Microphone section, click the drop down menu to view all available microphone devices.
5. Select the device name of the connected audio interface.
