Hear exactly how the HDL300 sounds in a large space, including how it handles the trickiest conferencing scenarios.
Get true full-room audio coverage in all your large spaces – without the complications of a traditional pro AV system. The HDL300 is an integrated microphone and speaker bar that ensures voices are picked up clearly, making it ideal for spaces up to 25' x 25' (7.6 x 7.6 m), including meeting rooms, classrooms and more.
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.
Powering the HDL300 system is patented Microphone Mist technology, the revolution 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 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 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 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.
Designate a zone in the room where microphone pickup is maintained while pickup in the rest of the space is reduced.
Use precise sound location data to steer and switch your third-party cameras so remote participants always see who’s speaking.
The HDL300 includes a 2-year subscription to Nureva® Pro. Add up to 3 years to your subscription to keep all these features plus extend your warranty.
Get access to knowledgeable experts when you need them. With Nureva Pro, support is available 20 hours a day (5 days a week) to quickly resolve issues.
Ensure your space gets back up and running quickly if a unit ever needs to be replaced. If we can’t fix the problem, we’ll ship you a replacement unit the next business day.
Unlock extra features in our cloud-based management software, including email alerts, acoustic insights, historical usage data and a room data API.
Discover the secret to easier audio:
Plug it in and it just works. It’s that simple.
With full-room microphone coverage, simple installation and cloud-based device management tools, the HDL300 system is the easiest and most cost-effective way to equip your large 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.
Remotely install firmware updates, check device status, adjust audio settings, dive into analytics data and more – all from a secure, cloud-based platform.
Get versatile APIs that make it easy to integrate your Nureva devices with other products, automate tasks and enable third-party camera switching and steering.
Enjoy Nureva Pro free for 2 years, including expanded support hours, advance hardware replacement and enhanced Nureva Console features. You can also add up to 3 years to your subscription to keep these features and extend your warranty.

No – all you need is a computer running a UC&C platform. No extra speakers, components or DSP are required. To get updates and manage the system, be sure to install Nureva Console on your in-room computer.
Yes. Although the HDL300 comes with integrated 20-watt speakers, you can also connect it to your own speakers if you prefer.
One of the most popular features of the HDL300 (and all Nureva systems) is the fact that we keep adding features and making improvements. To get regular firmware updates, be sure to register your system in Nureva Console.
Nureva’s patented Microphone Mist technology fills a room with thousands of virtual microphones (an HDL300 system deploys up to 8,192). Each virtual microphone is a point in space where two or more physical microphones (there are 12 in an HDL300) work together intelligently to focus audio pickup. Microphone Mist technology listens to each virtual mic simultaneously and optimizes each one for natural conversations.
When two people talk at the same time, the HDL300 system focuses on the stronger signal (the louder voice), while the other voice drops into the background. The effect is as if you were standing in the room close to the louder talker, but are also aware that someone else is speaking at the same time.
The system monitors and adjusts to the location of a talker 10 times per second.
Yes, but please note that not all UC&C systems support stereo audio.
Yes. The HDL300 system is certified for Microsoft Teams and Zoom and works with all leading UC&C platforms out of the box. It is recognized as a standard USB audio device.
The HDL300 system will work with any system that accepts clean, echo-canceled input for audio. The product supplies audio through USB or 3.5 mm auxiliary in and out ports on the connect module.
The microphone and speaker bar hangs on the wall on two screws and connects to the connect module via an Ethernet cable (included). The connect module can also be mounted on the wall, under a table or wherever it is convenient. It is connected to a power source and to your computer via a USB cable (included). You can install the HDL300 system in about 30 minutes – no specialized skills or technicians are required.
No. Like all Nureva audio systems, the HDL300’s Microphone Mist technology autocalibrates at setup and continuously during use. It senses and adjusts to changes in room characteristics automatically. No technician is required to set up or maintain the system.
Yes, two HDL300 systems can be combined to provide flexible audio for divisible rooms. With the addition of an Ethernet switch, the two systems can run together when a space is not divided, resulting in full-room audio coverage in rooms up to 30' x 50' (9.1 x 15.2 m). It’s easy to switch back to running the two systems independently when the room is divided. Find out more.
A 2-year Nureva Pro subscription comes with the HDL300. With your subscription, you receive extended access to technical support, advance hardware replacement and enhanced Nureva Console features. You can add up to 3 years to your Nureva Pro subscription and keep all those features plus extend your warranty.
