Release notes   

The Dual HDL300 system is available in 35 countries, with more coming. Learn more on our Find a distributor page.

Nureva’s patented Microphone Mist technology fills a room with thousands of virtual microphones (a Dual HDL300 system deploys up to 16,384). Each virtual microphone is an individual “pickup point” created when two or more physical microphones (there are 12 in each mic and speaker bar – 24 total) 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 Dual 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 Dual HDL300 system is recognized as a standard USB audio device and works with most UC&C platforms out of the box.

The Dual 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.

You can install the Dual HDL300 system in less than two hours – no specialized technicians are required. Each of the two microphone and speaker bars hangs on the wall on two screws. The system 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 Dual 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.
