With refined aesthetics and 4,096 virtual microphones providing true full-room coverage, the HDL200 system is purpose-built for any small room – from huddle rooms to meeting and flex spaces – up to 18' x 18' (5.5 x 5.5 m).
It’s about freedom. Unlike all-in-one mic/camera bars, the HDL200 system gives you the freedom to choose your own camera and place it where it gives you the coverage you want. Still want your camera attached to the HDL200? We offer a magnetic mounting bracket for that, too.
With the HDL200, we created a design suited to more intimate spaces. It’s why we softened its look with unique acoustic fabric coverings (available in a light tone and a dark tone) and rounded edges. It looks as good as it sounds no matter how your room is styled.
The built-in, configurable LCD gives you helpful information. On first-time startup you’ll know when the system is finished autocalibrating. During normal operation you’ll see call status and the time of day. And more features and integrations with room management systems are coming soon.

Traditional
With a typical beamforming microphone system, pickup is determined solely by the direction each mic is aimed. This is important because the automatic gain control circuit for each mic will not be able to assess how far away a talker is from the mic, even in a small space. The system also might not be able to differentiate talkers from other sound sources (e.g., HVAC, typing). All signals – desired and undesired – get equal treatment. This is especially problematic in small spaces where there may be a higher concentration of sources or unwanted sounds. Systems using directional pickup also often require a higher level of processing to be added to the signal.
New
The HDL200 system with Microphone Mist technology fills a huddle room or small meeting room or flex space with thousands of virtual microphones that let the system know the best sound source of each talker in the room – even when they are in motion. This enables the system to use position-based gain control (PBGC) to make specific optimizations to both the microphone system and the processing of every sound source in the room. This means the HDL200 system enables more natural conversations because the system optimizes the talker’s gain while keeping ambient noise at a quieter and more consistent level.
Traditional
AGC is the strategy employed in most traditional audio conferencing systems. It keeps the audio output level within a targeted minimum-maximum range by adding gain to the signals from quiet talkers and reducing gain on the signals from loud talkers. But AGC on a microphone treats the audio signal holistically. It increases the signal from the talker and ambient sounds equally. When it raises the talker’s level, it also raises the level of the ambient noise floor. This can create an unsatisfying listening experience.
New
Microphone Mist technology takes an innovative approach by listening simultaneously to each of the thousands of virtual microphones it deploys in a room (these are the “positions” in PBGC). Recognizing the position of each sound source, Microphone Mist technology adjusts the gain so talkers can be heard clearly while the level of ambient noise is kept lower and more consistent. This allows the remote caller to experience clear, natural-sounding conversations.
Traditional
Conventional systems (especially complicated in-ceiling installations) typically deal with acoustic return echo by having a technician manually calibrate the echo canceller system to the distinct acoustic properties of a room. A calibration signal – a short tone – is sent through the speaker system and then is picked up by the microphone system. The system measures the acoustic return echo delay and uses that data to calculate echo canceller parameters. It can be a time-consuming and intrusive process, and, since the room must be quiet during the process, it is not practical while a meeting space is in use. This means the room must be taken offline. Any additional changes to the room will likely also impact echo canceller performance and make it necessary to recalibrate the system again.
New
Luckily, there is a solution: continuous autocalibration, a proprietary process built into Nureva’s Microphone Mist technology. Continuous autocalibration entails measuring the acoustic environment of a room in real time for each microphone and speaker combination. It uses a sound mask-like signal that, if heard at all, is perceived as the background ambient noise common in most commercial environments. No technician is required, and there is no need for the loud calibration signal of the manual process, meaning also that the room doesn’t have to be quiet. Continuous autocalibration means the echo canceller will automatically deliver consistent performance throughout any call.
Traditional
Traditional technologies for microphone coverage for small spaces, such as beamforming, subdivide a room into large zones (there are as many zones as there are microphones). For example, if there are three zones in a beamforming array, you get low spatial resolution information. And while the coverage zones may be large, traditional systems are not able to discriminate individual sound sources within each zone. This results in a diminished ability to optimize individual sound sources in a zone for the correct gain setting, noise filtering and overall audio signal optimization. This isn’t just a problem for larger spaces – low-resolution audio can seriously affect audio performance in small spaces, too.
New
The HDL200 system’s Microphone Mist technology fills a room with up to 4,096 virtual microphones, subdividing the room into thousands of spatial bubbles for higher spatial resolution of audio signals. This means the system can isolate and zoom in on individual talkers, providing it with more audio information that in turn enables it to optimize both acoustic microphone pickup performance and post-processing of the audio signal.
