The TM2 is an Integrated Acoustic Coupler for In-Ear Monitors (IEMs) specifically designed for use in the professional sound industry.

Ear simulator “couplers” are the measurement devices used by manufacturers of IEMs for capturing key metrics during research & development, final production and quality control of IEMs. Using patent-pending technology, the TM2 incorporates the functionality of lab-type testing equipment into an integrated compact package, ideal for live sound and studio engineers who want a simple, yet effective way to test IEM performance.

Monitor engineers are often faced with questions from performers regarding the functionality of their IEMs with no reliably consistent method to test them in their environment. With the TM2 and readily available measurement software such as SMAART, a monitor engineer can easily confirm the functionality of each performer’s IEMs.

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.
