It’s all on the wall

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

Processing power

Runs at 15,000 MIPS – far exceeding the processing power in most traditional systems.


The processor drives 12 omnidirectional microphones to deploy 8,192 virtual microphones.


Two 20-watt speakers provide crisp sound for all your audio conferencing and playback needs.

Configuration diagram

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 an hour. 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.
