User Manual
Complete user guide covering installation, configuration, and operation of the ATS system.
Overview
The Echo ATS (Acoustic Test System) is Echo’s next generation of test equipment for acoustic test and measurement applications. It represents the evolution of the modular Echo AIO product line into a single compact interface with improved quality and enhanced features. The Echo ATS interface, and its companion AIO-BT Bluetooth LE module, provide the capabilities most needed for production and QA/QC testing of consumer audio devices and their components. These include phones, tablets, speakers, micro-speakers, earbuds, headsets, amplifiers, and other acoustic / electro-acoustic applications.
