The AIO-AC is a multifunction audio test interface with two amplifier outputs, two differentially balanced line-level outputs, four microphone inputs, dual DC power supplies, auxiliary GPIO control, 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 line-level outputs can also drive headphones.
The AIO-AC provides a constant 5 volt DC power supply along with a variable DC low-power supply up to 2 volts. The variable power supply can also measure DC current.
The auxiliary jacks each have 8 pins of software-controllable GPIO.
The AIO-AC presents a standard sound card interface and is compatible with most acoustic test software.
