Specifications
All the onboard processing power you need for high performing audio is built right into your Dual HDL300 system. There’s no need to purchase and set up a traditional DSP, simplifying your installation and maintenance.
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.
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.
HVAC and other unwanted sounds can seriously affect your audio performance. So instead of trying to suppress them after the fact, we use adaptive learning algorithms to preemptively ignore them.
We apply gain separately to each sound in a space based on its position, creating a natural listening experience for remote participants.
With our technology, you never need to recalibrate your systems manually. Your Dual 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.
Amplify a presenter or instructor’s voice in the room without compromising the listening experience of remote attendees.

With our systems, it isn’t just about what you’re hearing – it’s about what you’re not hearing. We take a groundbreaking approach to the problem of persistent unwanted noises, like HVAC systems and projector fans. Instead of attempting to suppress them in post-processing, we use adaptive learning algorithms to preemptively ignore them. The result? You hear voices better and unwanted noises less.
Unlike approaches that apply gain to all sounds equally within a microphone pickup area, our technology identifies the best position of each sound source in the room. This lets us make specific optimizations to both the microphones and the processing of each sound source. Remote participants have an easier listening experience without the distraction of uneven audio.
Automatic gain control keeps audio output levels within range by adding more gain on soft talkers. But both the talker and ambient sounds are treated equally, resulting in increased levels of background noise when quiet people speak. This can be very distracting to remote participants.
We accommodate both loud and soft talkers by providing gain appropriate to the sound source position in the room while keeping ambient noise consistent. The result is a signal-to-noise ratio appropriate for that position, which directly translates into a less fatiguing remote experience.
Don’t adjust your audio every time you adjust your space. Our systems automatically and continuously adapt to a room’s acoustic profile. This means you can change your room – add furniture or adjust orientation – without the need for manual calibration. You can even move a system to another spot in the room and it immediately works – no fine-tuning needed. Traditional conferencing technology may require you to adjust mics, fine-tune noise reduction and echo cancellation or even add components to keep rooms sounding right.

Active Zone Control allows you to designate an “active” zone where microphone pickup is maintained while pickup in the rest of the space is reduced.
This means that lecturers or presenters can move freely in the active zone, confident that remote participants can hear them clearly above the voices of those outside the zone.
It’s easy to use the system remote to toggle back to full-room pickup when it’s time for questions from the audience or broader discussion.
Set the active zone for the required dimensions at the front of the room, and the person speaking can be heard more clearly while sounds and voices from the rest of the space are suppressed. It adds up to better audio for remote audience members and lecture capture.
When it’s time for group discussions or questions from the class or audience, switch to the full zone setting to activate all the virtual microphones in the space so everyone in the room can be heard by remote participants.
To adjust the active zone’s dimensions, open Nureva Console, navigate to the device settings and open the Active Zone Control accordion. Drag the handles or enter the length and width of your desired active zone.
