    TM2 - Overview

    The Audix TM2 is the perfect tool for live sound engineers, studio engineers and pro audio service departments who want a simple and effective way to test in-ear monitors (IEMs) for potential damage or performance degradation. The TM2 combines the functionality normally associated with bulky and expensive IEM testing equipment into a compact, easy-to-carry, and easy-to-use package.

    Musicians often damage IEM devices over time without knowing, with the resulting degradation negatively affecting their performance. Monitor engineers can also face complaints about IEM functionality with no good way to confirm if there is an equipment problem. With the TM2, IEM functionality can be verified before every performance.

    By pairing the TM2 with test and measurement software, a transfer function of an in-ear monitor can be easily generated and compared to previous measurements of the same device. Doing so will highlight any frequency or phase changes due to device damage or degradation over time. Comparing the performance of the left and right earpieces can also aid in troubleshooting.

    With its included adaptors, the TM2 can fit any size of in-ear monitor. The TM2 can also be connected to an acoustic calibrator for greater measurement precision.
