Nureva HDL 300

Nureva HDL 300 audio conferencing system is a wall-mounted integrated microphone and speaker designed for medium to large-sized rooms. The system will provide the audio performance you need without desktop clutter or an expensive, intrusive installation of a mic array and speakers.

HDL 300 takes an entirely new approach to meeting room microphones that’s changing audio conferencing with its patented Microphone Mist technology. It leaps past traditional audio technologies, filling a space with thousands of virtual microphones to provide true full-room pickup. Microphone Mist technology has the astonishing capacity to process sound from all its virtual mics in real time. It focuses on the right sound sources, without gating or clipping, and optimizes them for distortion-free, natural sounding conversations.

Autocalibration is a continuous process and occurs while the HDL 300 system is powered. No user action is required to start or maintain the autocalibration process. It will continue to adapt and recalibrate to accommodate changes in the room, such as the number of people or the configuration of furniture.

Compatibility with other systems is important, here are just some of the platforms supported by Nureva audio conferencing systems: UC&C: Microsoft Teams, Skype for Business, Zoom, Cisco WebEx, Google Hangouts and GoToMeeting. Room-management controllers: Cisco Codecs, StarLeaf and Dante. Interactive display solutions: Intel Unite and Microsoft Surface Hub.
