A screw-lock removable gooseneck microphone with a two-colour LED ring and anti-wind foam, available in five lengths from 220 mm to 600 mm. A precise mini cardioid condenser capsule plugs into the DIALOGUE discussion units through a Mini 6-pin screw-lock socket.
Specifications as per the official Bronx BR-DCU-G Series datasheet (2026, Rev. A). Specifications may change without prior notice.
The two-colour LED ring shows speaking (red) and request-to-speak / awaiting chairman (green), while strong audio pickup and immunity to GSM / mobile interference keep speech clear across every gooseneck length. Choose the length that suits chairman and delegate positions — the electrical performance is identical across the range.
