Microphone Mist Technology

Powering the Dual 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

With 16,384 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.


Continuous autocalibration

With our technology, you never need to make manual adjustments when you reconfigure your space. The system is automatically and continuously adapting to changes in your room’s acoustic profile.


Intelligent Sound Targeting

HVAC and other unwanted sounds can seriously affect your audio. So instead of trying to suppress them after the fact, we use adaptive learning algorithms to preemptively ignore them.

Simultaneous processing

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.


Position-based gain control

We apply gain separately to each sound in a space based on its position. This lets us make specific optimizations that create a natural listening experience for remote participants – as if they were in the room.


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 – all processing power is built in
  • No complicated wiring or invasive ceiling installs
  • No restrictions on camera placement
  • No lengthy configuration processes
  • No compatibility problems with your existing technology products

Plug it in and it just works. It’s that simple.


Built for flexibility

With full-room mic coverage, easy installation and cloud-based management tools, the Dual HDL300 system is the easiest and most cost-effective way to equip your large spaces.
