Audix TM-1 Plus Test and Measurement Condenser Instrument Microphone Overview:

The TM1PLUS is a combination kit which includes the TM1 measurement microphone, threaded acoustic windscreen, shock mount clip, inch calibrator adaptor and microphone calibration data on CD. The data files are a numeric representation of the TM1 frequency response. These, along with the provided sensitivity of the microphone, can be used with a variety of popular software measurement systems to correct the response curve of the microphone.

The TM1 is a 6 mm pre-polarized condenser microphone used for test and measurement applications. Known for its linearity, the TM1 is very consistent and has a particularly accurate response. The TM1Plus is not complicated to use and with the additional supplied accessories is great value.

Characterized with 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 25 kHz, the TM1 is an excellent tool for sound engineers, sound companies and recording enthusiasts.

Requiring 18 – 52 V phantom power for operation, the TM1 features a precision machined four stage brass body and capsule housing, nickel plate finish, Switchcraft or Audix XLR and shock absorbent O-ring.
