16,384 virtual microphones

Microphone Mist™ technology fills a room with 16,384 virtual microphones so everyone can be heard, no matter where they move in the room.


A fraction of the cost

Quality audio conferencing for large rooms usually comes at a premium. The Dual HDL300 delivers high quality for much less than conventional systems.

Easy DIY Installation icon

Easy DIY Installation

Hang two HDL300s on the wall yourself in less than 60 minutes. There are no drivers to install and you use your preferred UC&C platform.


Big benefits for large rooms

Using just two microphone and speaker bars, the Dual HDL300 provides true full-room pickup in spaces up to 30' x 50' (9.14 x 15.24 m) no matter how they are configured. Compare that to other systems that require numerous mics but still leave zones where participants can’t be heard.
