A new-generation speakerphone with four high-SNR beamforming microphones and two extension microphones, AI echo cancellation and noise reduction, and a professional sound chamber, covering large conferencing rooms.
Specifications as per the official Bronx datasheet (2026, Rev. A). Specifications may change without prior notice.
The BR-SP360 pairs four high-SNR beamforming microphones with two extension microphones to cover large rooms (main microphone 3 m, extended microphone 2 m), while new-generation AI (CrossNet) delivers echo cancellation and noise reduction for clear, full-duplex calls. A professional sound chamber with matched tweeter and bass units gives hi-fi desktop audio in an aluminium body.
