Product Information

1. Introduction

The Echo AIO-L1 is a multichannel acoustic interface designed for production-line testing and QA/QC verification. Combining two balanced line-level/headphone outputs and four mic/line analog inputs in a single unit, the AIO-L1 is an integrated, cost-effective, and reliable high-throughput audio test solution.

Each input can be individually configured as a line level input or as a measurement microphone input. Microphone inputs include an IEPE microphone conditioning amplifier with integrated constant current power supply (CCP). Line level outputs can also drive most headphones.

The AIO-L1 presents a standard USB audio sound card interface and is compatible with most audio test software including APx Flex.
