Product sheet

It’s all on the wall

The HDL300 system has the key audio conferencing system elements in an integrated wall-mounted unit. You get the audio performance you need without desktop clutter or an expensive, intrusive installation of a mic array and speakers.

Processing power

Runs at 15,000 MIPS – far exceeding the processing power in most traditional systems.


The processor drives 12 omnidirectional microphones to deploy 8,192 virtual microphones.


Two 20-watt speakers provide crisp sound for all your audio conferencing and playback needs.

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 an individual “pickup point” created when two or more physical microphones (there are 12 in an HDL300) work together to focus their sound pickup on a distinct zone. 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 many UC&C systems do not provide optimal stereo performance.

Yes. The HDL300 system is recognized as a standard USB audio device and works with most UC&C platforms out of the box. The HDL300 is certified for Microsoft Teams.

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 HDL300 system is quick and easy to install. You can do it yourself in less than an hour – no technician is required. The microphone and speaker bar hangs on the wall on two screws and connects to the connect module via a PoE 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).

No. Like all Nureva audio systems, the HDL300’s Microphone Mist technology autocalibrates at set up 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.
