Using multiple microphones is particularly useful in large or medium Zoom Rooms where a single microphone might not detect the sounds from all parts of the room. When using multiple XLR-based microphones, you can configure them as a single device within a Zoom Room so they can be managed together. When this configuration is used, the Zoom Room software audio processing automatically detects which microphone needs to be active at any particular time, without the need of an external DSP. 

Prerequisites for configuring multiple XLR microphones

• Zoom Rooms license
• Microphone:  Audio Technica XU851RO Table Mic, Shure MX202 Overhead Mic, or Audix M3 Tri Element Hanging Mic
• Speaker: Samsung Soundbar or QSC Amp with Ceiling Speakers
• Audio Interface: Focusrite Scarlett 18|20 or Behringer U-Phoria UMC1820

Note: The Behringer U-Phoria UMC1820 interface is only compatible with Windows 10 using the default windows device driver.

How to configure multiple XLR microphones in a Zoom Room
