Nureva® HDL310 system
The HDL310 audio conferencing system makes full-room mic pickup easy to achieve in spaces up to 30' x 30' (9.1 x 9.1 m). Installation is refreshingly simple, and features like continuous autocalibration keep maintenance and programming to a minimum. Certified for Microsoft Teams and Zoom, the HDL310 is built for fast deployment and long-term reliability.
Nureva HDL410 system
The HDL410 audio conferencing system makes it easy to equip extra-large spaces up to 35' x 55' (10.7 x 16.8 m). With just two microphone and speaker bars and a connect module, installation takes as little as 60 minutes — no need for specialized skills or tools. Certified for Microsoft Teams and Zoom, the HDL410 is a future-ready solution that’s as easy to deploy as it is to use.
Do you have an HDL300 system? Upgrading is simple!
Just swap out the connect module to transform an HDL300 into an HDL310. There’s no need to move the microphone and speaker bar or reconfigure the space. You won’t need extra hardware, cables or accessories, and the new connect module includes a new power supply.
Have a Dual HDL300 system? You can replace the connect module to turn it into an HDL410. The bars stay in place, so setup takes minutes.

Full-room mic pickup
Our Microphone Mist™ technology fills large spaces with thousands of virtual microphones, so there’s always one nearby. People in the room can be confident they’ll always be heard by those who are remote.
Continuous autocalibration
There’s no need to calibrate your HDL300 manually. It’s always adapting to changes in your room’s acoustic profile, so even if you adjust the furniture or layout, the audio will still sound great.
Intelligent Sound Targeting
HVAC and other unwanted sounds can seriously affect your audio performance. So, instead of trying to suppress these noises after the fact, we use adaptive learning algorithms to preemptively ignore them.
Rapid conversation tracking
Our technology quickly switches pickup from talker to talker, no matter where they are in the room. Conversations sound natural, even when multiple voices overlap.
Position-based gain control
We apply gain separately to each sound in a space based on its position, creating a smooth and natural listening experience for remote participants.
HDL SERIES
Equip your medium and large spaces with flexible audio conferencing for less. Our HDL series delivers true full-room mic pickup in economical systems that are simple to install, use and maintain, making them easy to deploy at scale.
