Background Noise Reduction

Nexus 50 is the first speakerphone from Accutone to use AI algorithm for background noise reduction in office conference calls. Turn NR on for maximum clarity or turn off NR for more natural audio playback. Also using 4 microphones arranged in a 360º array to pick up voices from all directions, Nexus 50 is also a Dual-Mode (Bluetooth and USB) speakerphone with advanced DSP for full-duplex and echo cancellation. Acoustically tuned for Microsoft Teams and Zoom, Nexus 50 is the advanced solution for professional calls in both conference room and home office environments. 

Nexus 50 is compatible with Sonar UAC bluetooth dongle to convert any USB audio device into native bluetooth connectivity, 100% driver-free.
