Audix TM2 Integrated Acoustic Coupler for In-Ear Monitors

 The TM2 is an Integrated Ear-Simulator (coupler) specifically designed for test 
and measurement in the professional sound industry.
 Ear simulator “couplers” are the measurement devices used by manufacturers 
of IEMs for capturing key metrics during research and development, final 
production and quality control of IEMs. Using patent-pending technology, the 
TM2 incorporates these features into an integrated compact package that is 
ideally suited for 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 Rational Acoustic’s SMAART or Studio Six Digital’s Audio Tools, a 
monitor engineer can easily confirm the functionality of each performer’s IEMs  
as part of a pre-show checklist.
