Audix TM1 Plus Measurement Microphone Kit

The TM1 Plus takes Audix's TM1 test and measurement microphone and adds what a calibration workflow actually needs: a calibration data file with sensitivity, a threaded acoustic windscreen, and a CA4231 machined calibration adapter for a Bruel and Kjaer 4231 sound level calibrator or equivalent. The 6 mm pre-polarized capsule is prized for its linearity and consistency in room analysis software and real-time analyzers.

The omnidirectional pattern is uniformly controlled across a flat 20 Hz to 20 kHz range, and like the standard TM1, it is all-brass, four-stage construction, designed, machined, assembled, and tested by Audix in the USA. It runs on 18 to 52 V phantom power.
