NUREVA
Dual HDL300
Meeting Room Audio Solution
- Microphone Mist technology
- Built-in sound masking
- 4 x 20W speaker
- Connect module
The HDL300 offers true full-room microphone pickup that lets you hear voices clearly no matter where people are sitting, looking, or moving — making it an affordable yet effective option for meeting rooms and classrooms up to 25' x 25' (7.6 x 7.6 m).
Like all Nureva systems, the HDL300 works with patented Microphone Mist™ technology that fills a space with thousands of virtual microphones. Only one HDL300 provides true full-room coverage. Compare that to traditional systems that use multiple components and can still leave dead zones where people can’t be heard. Continuous automatic calibration means your sound is always optimized, even if you change the room setup — and there’s no technician required.
