AUDIO CONFERENCING / HDL200 SYSTEM
Versatile microphone and speaker
bar for small spaces
Pick up every voice in your small meeting rooms with an audio system that is as flexible as it is stylish. The HDL200 audio conferencing system is purpose-built for spaces up to 18' x 18' (5.5 x 5.5 m). It can be mounted on the wall or easily attached to a mobile cart.
The HDL200 system was made to give great performance in unconventional configurations.
No need to stay seated at the table. You’ll be heard no matter where you move in the room.
Go ahead and change your space – as often as you like. You’ll always get great coverage.
Microphone Mist™ technology fills a room with 4,096 virtual microphones for true full-room coverage.
On the wall or display – or almost anywhere.
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.
Available in two neutral colors to complement any room.
Our patented technology fills a room with thousands of virtual microphones so everyone can be heard everywhere in a small space. It also enables unprecedented simplicity, because one easy-to-install microphone and speaker bar gives you the coverage and audio performance you need.
A beamforming system may only provide audio pickup for those seated at the table in small spaces. Microphone Mist technology provides true full-room coverage.

Nureva’s patented Microphone Mist technology fills a room with thousands of virtual microphones (an HDL200 system deploys up to 4,096). Each virtual microphone is an individual “pickup point” created when two or more physical microphones (there are 10 in an HDL200) 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 HDL200 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 HDL200 system is recognized as a standard USB audio device and works with most UC&C platforms out of the box. UC&C application controls (for volume and muting) work automatically with the HDL200 system.
You can install the HDL200 in less than an hour – no specialized technicians required. Attach it to the wall with two screws or mount it on a display or mobile cart. It is connected to a power source and to your computer via a USB cable (included). A camera mount is also available.
No. Like all Nureva audio systems, the HDL200’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.

There are several important areas of differentiation between the leading types of microphone technology for small spaces. Read on to learn how traditional beamforming technology compares to Nureva’s new Microphone MistTM technology when it comes to the underlying technologies, directional vs. positional pickup, low-res vs. high-res pickup and how each handles acoustic return echo.
Traditional audio conferencing systems for small spaces typically employ beamforming technology. This approach picks up sound in defined beams, usually pointed at fixed positions around the meeting room table or at the different zones in a flex space. Adequate pickup can be achieved as long as talkers stay within the beams. However, even in small room, if talkers move outside the beams, to spread out within the space or to present at a display, they may enter dead zones where pickup can be diminished. And if a talker moves between beams, the audio may rise or drop off noticeably. Also, all the sounds in each beam – desired sounds like talking, as well as undesired sounds like typing or fans – are picked up equally. This may result in an audio experience for remote participants that can be annoying or even fatiguing.
Like all Nureva® audio conferencing systems, the HDL200 system features patented Microphone Mist technology, which, in the case of the HDL200, fills a room with up to 4,096 virtual microphones or individual “pickup points.” Whether in a huddle room or small meeting room or flex space, there is always a virtual mic nearby each meeting participant, no matter where they are in the room or which direction they face – there are no dead zones. With advanced processing power, Microphone Mist technology listens at each pickup point simultaneously and focuses on the predominant sounds, such as talkers, and optimizes them for clear conversations. While other small-room systems might use “post-sound” processing to handle unwanted noises, our technology ignores consistent unwanted noise sources, like HVAC, displays or computer fans. This means a clear and consistent audio experience that is more inclusive for remote team members because they feel like they’re in the room.
There are two main approaches to how microphones pick up sounds in a small space: the traditional approach, aka directional pickup, and a groundbreaking approach called positional pickup. Let’s look at both:
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.
How well a system manages the level of each talker versus background ambient sounds and electronic hiss is one of the most significant factors in the quality of conference call audio. This balancing act is typically achieved by adjusting (lowering or boosting) the gain on an audio signal. There are two main gain control strategies: automatic gain control (AGC) and a new approach, position-based gain control (PBGC).
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.
Acoustic return echo, which is the effect of callers hearing their own voices in their headset or speaker delayed in time after they have spoken, is a common issue on many conference calls. It can make for a distracting and even annoying audio experience. Virtually all microphone systems handle this problem with some form of echo cancellation technology that is calibrated to the unique features of the room: shape and size, surface and furniture characteristics, and number and position of people. There are two main strategies for calibrating a system for echo cancellation:
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.
You know that a higher resolution camera or display delivers a clearer picture. Having higher resolution in microphone pickup also matters.
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.
