AIO
Test System

The Echo AIO ™ Test System is a modular audio test platform ideally suited for high-volume continuous mass production. The AIO combines the functionality of multiple standalone devices into a single, integrated unit, making test stations both more reliable and less expensive.

The AIO comes in a variety of configurations with flexible analog and digital I/O options.

The AIO is USB 2.0 audio class compliant, so it works just like a sound card. Standard audio drivers provide seamless support with industry-leading audio test software.

The design of the AIO draws on our decades of experience creating high-quality consumer and professional audio interfaces. Since its introduction in 2014, the AIO has been used to test hundreds of millions of products. The AIO is a proven, field-tested, cost-effective, and accurate audio test solution.
