The TM2 from Audix USA is an integrated acoustic coupler designed for use with in-ear monitors.

From The Lab To The Stage...

Couplers – also known as ear simulators – are measurement devices used by IEM manufacturers for developing and quality controlling in-ear headphones. Using patent-pending technology, Audix's TM2 offers lab-style testing for IEMs in a compact and highly versatile package.

Sound engineers both in studio and live settings will often be queried on the functionality of monitoring tools. This is particularly true of IEMs as an artists best insight into the stage or studio mix. By utilising the TM2, the performance and functionality of in-ears can be quickly tested even in less-than-ideal environments.

Wide Ranging Compatibility

The Audix TM2 can be used in conjunction with market leading calibration software such as Rational Acoustic’s SMAART and
Studio Six Digital’s Audio Tools. 

With its concise range of included adaptor accessories, TM2 is compatible with almost any major IEM size, and can also be attached to an acoustic calibrator for even more precise measurement.
