Audix TM2 Earphone Couplers for In-Ear Monitors (Single)

Designed for measuring in-ear monitors often used on stage, the Audix TM2SP is an accoustic coupler intended for conducting tests on any pair of IEMs. Think of the TM2 as a measurement microphone system, but instead of a pair of speakers, you're measuring the frequency response and other performance specs of in-ear monitoring systems to make sure they're ship-shape for use on stage.
