A low-profile, all-metal cardioid condenser boundary microphone that hides when not in use. A reed switch turns it on when raised and off when retracted, and a built-in preamp removes the need for an external supply.
Specifications as per the official Bronx datasheet (2026, Rev. A). Specifications may change without prior notice.
For desks and conference surfaces: push the top until it clicks to raise or retract it. It pairs with the BR-DCU-CUIB to join the BRONX networked dialogue system. Output is by 3-pin XLR or 3.5 mm Phoenix (add the BR-DCU-CUIB for network configuration).
