PERFORMANCE CHECK
Audix, a leading US manufacturer of microphones and wireless microphone systems for the installed sound and professional audio markets, is now shipping the TM2, an Integrated Acoustic Coupler for In-Ear Monitors.
Ear simulator “couplers” are the measurement devices used by manufacturers of IEMs 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. Featuring precision-machined brass and aluminum components, the TM2 is built for the road and includes adapters to fit a wide range of IEMs including custom molds.
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 before the show. It is also ideal for house of worship applications, where the TM2 can be used to check the performance of the IEMs of every member of the praise team on a regular basis.
“We saw a need for a tool that didn’t really exist, and instead of waiting for one to come along, we just built it,” says Steve Young, Director of US Sales at Audix.
DEVELOPMENTAL HISTORY
During a decade as Mix magazine's Live Sound Editor, Mark Frink wrote several features on In-Ear Monitors. "At that time there were only a few manufacturers, and since IEMs are subjective, as well as unknowable prior to purchase, a SIM machine was used to measure the response of each maker's model," he explains. "This led to the need for a reliable acoustic coupler between the measurement mic and IEM, and was the genesis of an 8-year discussion with Audix's Fred Bigeh that led to the TM-2."
