HDL300 system

Provides true full-room pickup for small to mid-size spaces up to 30' x 30' (9.14 x 9.14 m). Powered by Microphone Mist™ technology, which fills a space with 8,192 virtual microphones. System processing capability is 15,000 MIPS. Audio features include full-duplex transmission, continuous autocalibration, acoustic echo cancellation, built-in sound masking and position-based automatic gain control (AGC). Can be used as the primary audio source for video playback. Available in black or white.

US$2,999 MSRP*

Works how you work

While most traditional audio conferencing systems only provide adequate pickup for team members seated at a conference table, the HDL300 system is designed for any room configuration.

Flex room

Seated at the table or moving around the room everyone can be heard with the HDL300 system.

Studio space

Unconventional room arrangements may challenge traditional audio conferencing systems, but the HDL300 system handles any configuration.


Microphone Mist technology

Patent-pending Microphone Mist technology is the brains behind the HDL300 system. While traditional beamforming and tabletop omnidirectional systems leave dead zones where people can’t be heard, Microphone Mist technology fills a room with thousands of virtual microphones to deliver true full-room pickup. For the first time, team members can be heard no matter where they move in the room or which direction they face.

Lots of mics. Loads of benefits.

Easy installation

Easy installation

The HDL300 can be installed in less than 30 minutes. No technician required. Use your preferred UC&C platform. There are no drivers to install.



Calibration is automatic for any room configuration or meeting style. No technician required. Nureva Room Manager keeps your system current.

Speakers for all your audio needs

While some traditional conference call microphone systems ask you to purchase and install separate speakers, the HDL300 system includes two integrated 20 watt speakers designed for meeting spaces. They provide clear, high-performance output for audio conferencing and all your in-room audio needs, including from external devices.

Perfectly simple.

Install the microphone and speaker bar, run a cable to the connect module and another to a computer with UC&C software and you’re ready.

Award-winning tech

The HDL300 system is built on completely new technology and delivers exceptional performance. No wonder it’s captured six industry awards. See them all here.

  • Product Innovation Award

    Excellence in Product Innovation – Trailblazing Innovation category. From the National Systems Contractors Association.

  • Best of ISE

    Best of ISE 2018 – Best Audio Conferencing Product. From rAVe Publications for the Nureva™ Dual HDL300 system.

  • Top New Technology

A virtual microphone is an individual “pickup point” created when two or more physical microphones (there are 12 in an HDL300 bar) work together, through proprietary processing algorithms, to focus their pickup patterns on a configurable zone. Thanks to advanced processing power, the HDL300’s Microphone Mist technology listens to each virtual microphone simultaneously, and chooses the predominant sounds and optimizes them for clear 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 person speaking 10 times per second.

Yes, but please note that many UC&C (unified communications and collaboration) systems do not provide optimal stereo performance.

No integration is required. The HDL300 system is recognized as a standard USB audio device. UC&C application controls (for volume and muting) work automatically with the HDL300 system.

The HDL300 system is quick and easy to install. It can take less than 30 minutes. The microphone and speaker bar hangs on the wall on two screws and connects to the breakout box via a PoE cable (included). The connect module can also be mounted on the wall, under a table or wherever is convenient. It is connected to a power source and to your computer via a USB cable (included).


The HDL300 system is very easy to deploy. It calibrates automatically at set up and constantly during use. The system senses and adjusts to changes in room characteristics automatically. No technician is required to set up or maintain the system.

The HDL300 system will work with any system that accepts clean, echo-canceled input for audio. The product supplies audio through USB or 3.5mm auxiliary in and out ports on the connect module.

The HDL300 system is currently available in North America, Europe, Australia and New Zealand. A detailed list of countries can be found here. We plan to expand to additional global markets in 2018.
