The key to Microphone Mist technology, a virtual microphone is an individual “pickup point” created when two or more physical microphones (there are 12 in each of the two Dual HDL300 microphone and speaker bars) work together, through proprietary processing algorithms, to focus their pickup patterns on a configurable zone. Microphone Mist technology listens to each virtual microphone simultaneously and chooses the predominant sounds, optimizing them for clear conversations.

When two people talk at the same time, the Dual HDL300 system focuses on the stronger signal (the louder voice), while the other voice drops into the background. The effect is a natural listening experience.

Yes.

Installing the Dual HDL300 can take less than two hours. The microphone and speaker bars hang on the wall on two screws (each) and connect 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).

No. The Dual HDL300 system autocalibrates at set up and continuously 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 Dual HDL300 system is currently available in North America, Europe, Australia and New Zealand. We plan to expand to additional global markets in 2020.
