The science behind the technology
The Dual HDL300 takes a completely new approach to the science of meeting toom microphones. The Microphone MistTM technology will transform conference call audio in large spaces by placing up to 16,384 virtual microphones throughout a meeting room to pick up sound from any location. Enabled by real-time hardware, the solution uses sophisticated algorithms to simultaneously process sound from all virtual microphones to provide remote participants with the highest quality listening experience.
The Dual HDL300 custom audio processing units are capable of handling up to 25,000+ MIPS. This power is used to create the quality listening experience, the virtual microphones, continuous self-calibration, simultaneous echo cancellation, position-based automatic gain control and sound masking. Listening to all microphones simultaneously, the systems dynamically select the one closest to the speaker, ensuring the best quality sound for people outside of the room.
Fully plug and play, the self-calibration feature means there's no technical setup or adjustment for the room. As the integrated microphone and speaker bars easily mount to the wall, it helps to eliminate table clutter and distracting noises while still picking up and delivering clear sound to all participant.
