Truly advanced audio conferencing

The HDL300 system lets everyone be heard on conference calls

8,192 virtual microphones in one room

The HDL300 audio conferencing system is new technology that finally lets everyone be heard on a conference call no matter where they sit or how they move in a meeting. Remote participants feel like they’re right there with their team. Powered by Nureva™ Microphone Mist™ technology, the HDL300 system fills a room with 8,192 virtual microphones and processes every audio source simultaneously. Now an idea can be heard from anywhere – the back of the room, in front of a display or even the other side of the continent.

Works with your current UC&C platform

Skype® for Business, Skype, Zoom, Cisco WebEx™, GoToMeeting™, StarLeaf, BlueJeans and most other unified communications and collaboration (UC&C) software are supported by the HDL300 system. It’s recognized as a standard USB audio device, and there are no drivers to install so it’s ready to go out of the box.

“Before switching to the Nureva HDL300 system, we had tried multiple audio conferencing platforms with inconsistent and unreliable audio performance. The HDL300 was easy to install, delivered superior microphone and sound capabilities, and has radically improved the audio conferencing experience for all participants.”

Luke Simpson, Director of Business Development and Marketing, CANA Group

Automatic calibration and updates

Calibrating conventional meeting room microphones can be difficult and expensive. The HDL300 system calibrates automatically and adjusts to changes in the environment. And Nureva audio manager automatically updates so you always have the latest software and firmware.
