The HDL300 offers true full-room microphone pickup that lets you hear voices clearly no matter where people are sitting, looking, or moving — making it an affordable yet effective option for meeting rooms and classrooms up to 25' x 25' (7.6 x 7.6 m).
Like all Nureva systems, the HDL300 works with patented Microphone Mist™ technology that fills a space with thousands of virtual microphones. Only one HDL300 provides true full-room coverage. Compare that to traditional systems that use multiple components and can still leave dead zones where people can’t be heard. Continuous automatic calibration means your sound is always optimized, even if you change the room setup — and there’s no technician required.
Powerful Features
Get everything you need to equip extra-large classrooms and meeting rooms for great audio experiences.
Connect Module
No DSP required
All the onboard processing power you need for high performing audio is built right into your HDL300 system. There’s no need to purchase and set up a traditional DSP, simplifying your installation and maintenance.
Microphone Mist Technology
Powering the HDL300 system is patented Microphone Mist™ technology, the breakthrough that audio conferencing has been waiting for. It fills rooms with thousands of virtual microphones so people’s voices are picked up everywhere – making Nureva the easiest and most cost-effective way to get true full-room audio coverage in all your spaces.
The virtual mic difference
Full-room microphone pickup Intelligent Sound Targeting Position-based gain control Continuous autocalibration Simultaneous processingFull-room microphone pickup
Full-room microphone pickupWith 8,192 virtual microphones filling your space, there’s always one nearby. People can speak and act naturally in meetings and classes and be confident they will be heard by those who are remote.
HVAC and other unwanted sounds can seriously affect your audio. So instead of trying to suppress them after the fact, the technology uses adaptive learning algorithms to preemptively ignore them.
The technology gain separately to each sound in a space based on its position, creating a natural listening experience for remote participants.
With the technology, you never need to recalibrate your systems manually. Your HDL300 is automatically and continuously adapting to changes in your room’s acoustic profile.
Microphone Mist technology listens to, and processes, all virtual microphones simultaneously. Conversations sound natural even when more than one person is speaking at the same time.
Additional features
Voice Amplification Mode
Amplify a presenter or instructor’s voice in the room without compromising the listening experience of remote attendees.
Active Zone Control
Designate a zone in the room where microphone pickup is maintained while pickup in the rest of the space is reduced.
Camera tracking
Use precise sound location data to steer and switch your third-party cameras so remote participants always see who’s speaking.

Up and running in minutes
Discover the secret to easier audio:
- No DSP required – advanced processing power is built-in
- No complicated wiring or invasive ceiling installs
- No need to purchase multiple separate components
- No lengthy configuration processes
- No specialized skills needed for installation and maintenance
Plug it in and it just works. It’s that simple.
Easy audio for divisible rooms
Do you have rooms with movable dividers or walls? Get great audio no matter how you’re using the space. With the addition of an Ethernet switch, the microphone and speaker bars from two HDL300 systems can work together as a single system, providing audio coverage up to 30' x 50' (9.1 x 15.2 m). It’s easy to change back to running the two systems independently when the room is divided.
Plays nicely with others
Use your HDL300 system with all leading UC&C platforms, including Microsoft® Teams and Zoom. As a standard USB device, it also works well with almost everything else you have in your spaces.
