AIO-S

Multichannel acoustic test interface with impedance measurement

AIO-S

The AIO-S is a multichannel acoustic interface built for production-line testing. Combining four amplifier outputs and six analog inputs in a single unit, the AIO-S is an integrated, cost-effective, and reliable mass-production audio test solution.

One of the amplifier outputs also incorporates dedicated voltage and current inputs for impedance measurement.

Each input features an IEPE microphone conditioning amplifier with integrated constant current supply and can also accept line level signals.

The AIO-S presents a standard USB audio sound card interface and is compatible with most audio test software.
