AIO-LT

Multichannel line-level test interface with TDM

AIO-LT
The AIO-LT is a combination analog and digital test interface with two line-level 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-LT TDM interface is software configurable and supports up to 10 full duplex channels.
The AIO-LT presents a standard sound card interface and is compatible with most acoustic test software.
