Cover large rooms for less

The Dual HDL300 system provides exceptional pickup in rooms up to 30' x 50' (9.1 x 15.2 m) with just two integrated microphone and speaker bars you can install on the wall yourself. No wonder it costs many times less than traditional large-room systems.

It's all on the wall

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

Processing power

Runs at 25,000+ MIPS – far exceeding the processing power in most traditional systems.


The processor drives 12 omnidirectional microphones per unit (24 total) to deploy 16,384 virtual microphones.


Two 20-watt speakers per unit (4 total) provide crisp sound for all your audio conferencing and playback needs.

Easy to use. Easy on the budget.

Microphone Mist technology

Patented 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.

The perfect fit for flex rooms

It’s not just about boardrooms anymore. Companies are embracing new styles of meeting rooms, like the flex room. Good thing the HDL300 systems automatically recalibrate to provide complete coverage for any room configuration – with no technician required.

New advances

Active Zone Control

Active Zone Control focuses pickup from the HDL300 and Dual HDL300 systems on a configurable zone and provides front-of-room focus so a presenter in front of a class or audience can be heard more clearly by remote participants.

Intelligent sound targeting

HVAC and other room sounds can seriously affect audio conferencing. Groundbreaking intelligent sound targeting solves this by using adaptive learning algorithms to learn unwanted sounds and simply stop picking them up.

Go big anyway you want

Large spaces used to require complicated and expensive multicomponent systems with many microphones. The Dual HDL300 provides exceptional performance with just two integrated microphone and speaker bars, so it costs a fraction of the price of traditional systems.

Large flex room

Micing a flex room with a traditional audio conferencing system can be difficult and expensive. And changing the room configuration would mean changing your system. The Dual HDL300 system autocalibrates so you reconfigure your room as often as you like.

Large boardroom

No need for individual tabletop microphones. The Dual HDL300 system picks up the presenter, seated team members and even those away from the table.

From the front row to the back, everyone can be heard in an HDL300-equipped classroom. Even the presenter is picked up, so that person won’t need an individual microphone.

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.

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 stronger 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 a standard audio device and is automatically recognized as such. UC&C application controls (for volume and muting) work automatically with the HDL300 system.

The Dual HDL300 system is quick and easy to install. It takes less than two hours, including routing the cables. Each 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 Dual HDL300 system is very easy to deploy. It calibrates automatically at set up and throughout its 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 2019.
