Audix M1255BO — High Output Mini-Condenser Microphone for Distance Miking
M1255BO Overview
The Audix M1255BO is a miniaturized condenser microphone purpose-built for distance miking scenarios where placement flexibility and high sensitivity are critical. Measuring only 54 mm in length, it integrates a fully functional preamp directly into the microphone body and features an omnidirectional capsule suited for ceiling mounts, table mounts, hanging choir configurations, audience miking, and location recording.

The M1255BO is designed for audio engineers, system integrators, houses of worship, broadcast facilities, and conference room installers who require a discreet, high-performance solution.
The detachable cable design simplifies installation and replacement, and the microphone ships with a 25-foot cable, clip, hanging clip, windscreen, and pouch. Designed, machined, assembled, and tested by Audix in the USA.
