AIO-A1

Multichannel Acoustic Test Interface

AIO-A1

The Echo AIO-A1 is a multichannel acoustic interface built for production-line testing and QA/QC verification. Combining two 10W amplifier outputs and four mic/line analog inputs in a single unit, the AIO-A1 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).

The AIO-A1 presents a standard USB audio sound card interface and is compatible with most audio test software including APx Flex, LabVIEW, Soundcheck, and ARTA.
