The TM1 is a 6 mm pre-polarized condenser microphone used for test and measurement applications. The TM1 is known for its linearity, accurate response, consistency, ease of use, and affordability.
Equipped with a uniformly controlled omnidirectional polar pattern, the TM1 condenser microphone is designed to capture acoustic measurements for room analysis software programs, real-time analyzers, and other sound control devices. With a flat frequency range of 20 Hz – 20 kHz, the TM1 is an excellent tool for sound engineers, sound companies, and recording enthusiasts.
The TM1 omnidirectional test and measurement microphone is designed, machined, assembled, and tested by Audix in the USA.
