Zoom Audio Settings


We use Zoom for 7-8 committee meetings per month. Meetings take place in various meeting rooms depending on availability. Our equipment setup is not permanent - equipment is set up before and packed away after each meeting.

Hardware-wise, we have two sets of microphone/speakers and cameras. The "small" system uses a Konftel OCC Hub with a Konftel Cam20 camera and single Konftel 55 conference phone. The "large" system uses a Konftel OCC Hub with Konftel Cam50 camera and three Konftel 800 conference phones, daisy chained to provide a single audio connection to the hub. Audio and video peripherals connect to the hub via USB. The Konftel OCC hubs connect via USB to a notebook running Zoom.

Despite having 3 audio devices on a long conference table used by up to 16 people, people joining the Zoom meeting outside the room frequently strugle to hear what's being said in the room.

Konftel's audio devices come with OmniSound enabled. "OmniSound® delivers HD sound in calls over IP and the mobile phone network, with automatic echo cancellation and noise suppression."

Here are my questions: Given that the Konftel audio equipment is already performing echo cancellation and noise suppression, should Zoom's Audio Profile be set to 'Original sound for musicians'? How should the Zoom Audio Advanced options be set (Signal processing by Windows audio device drivers [Auto, On or Off] and Echo cancellation [Auto or Aggressive])?

A photo of a typical meeting setup is attached.

Thanks in advance for any and all suggestions.
