AIO-2

Multichannel acoustic test interface

The AIO-2 is a multichannel acoustic interface built for production-line testing. Combining four amplifier outputs and eight analog inputs in a single unit, the AIO-2 is an integrated, cost-effective, and reliable mass-production audio test solution.
Each input features an IEPE microphone conditioning amplifier with integrated constant current supply and can also accept line-level signals.
The AIO-2 presents a standard USB audio sound card interface and is compatible with most audio test software.
