Audix TM2 — Integrated Ear-Simulator Coupler for IEM Test and Measurement
TM2 Overview
The Audix TM2 is an integrated ear-simulator coupler purpose-built for test and measurement applications in the professional sound industry. Ear-simulator couplers are the standard measurement devices used by IEM manufacturers to capture key performance metrics during research and development, production, and quality control. Using patent-pending technology, the TM2 consolidates these capabilities into a compact, integrated package that makes IEM verification accessible to working engineers outside of a lab environment. It is well suited for monitor engineers, studio engineers, and system integrators who require a consistent, repeatable method for evaluating IEM performance.
The TM2 is compatible with widely used measurement platforms including Rational Acoustics SMAART and Studio Six Digital Audio Tools, allowing it to integrate directly into existing pre-show or quality control workflows without requiring specialized proprietary software.
Key Features
- Integrated Ear-Simulator Design — Combines coupler measurement functionality into a single compact unit using patent-pending technology, eliminating the need for separate component assemblies
- IEM Performance Verification — Enables monitor engineers to confirm the functionality of each performer’s IEMs as part of a structured pre-show checklist
- Compatible with Industry-Standard Measurement Software — Works with Rational Acoustics SMAART and Studio Six Digital Audio Tools for flexible deployment in live and studio environments
- Designed for Field Use — Compact form factor makes it practical for touring engineers and venue technicians who need reliable IEM testing outside of a controlled lab setting
- Applicable Across the IEM Lifecycle — Suitable for R&D, final production verification, and ongoing quality control, mirroring the same measurement approach used by IEM manufacturers
- Consistent, Repeatable Results — Provides a standardized measurement reference, replacing ad hoc listening tests with objective, documentable data
