Audix TM1 Omnidirectional Test & Measurement Microphone

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.  

Characterized by a uniformly controlled omni-directional polar pattern, the TM1 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.  

Requiring 24 - 48 Volts phantom power for operation, the TM1 features a precision-machined 4-stage brass body and capsule housing, nickel plate finish, Switchcraft® or Audix XLR, shock absorbent O-rings, and heavy-duty snap-to-fit mic clip.
