AIO-AT

Multichannel acoustic test interface with TDM

AIO-AT

The AIO-AT is a combination acoustic and digital test interface with two amplifier outputs, four microphone inputs, full-duplex TDM, and a standard USB audio interface in a single unit.

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

The AIO-AT TDM interface is highly configurable and supports up to 10 full duplex channels.

The AIO-AT presents a standard sound card interface and is compatible with most acoustic test software.
