The Echo AIO-AC is a multichannel acoustic interface designed for production-line testing and QA/QC verification. Combining two 10W amplifier outputs, two balanced line-level/headphone outputs, four mic/line analog inputs, 8 GPIO inputs, 8 GPIO outputs, 5V DC power supply, and variable 2V DC power supply for battery simulation in a single unit, the AIO-AC is an integrated, cost-effective, and reliable high-throughput audio test solution.
Each input can be individually configured as a line level input or as a measurement microphone input. Microphone inputs include an IEPE microphone conditioning amplifier with integrated constant current power supply (CCP). Line level outputs can also drive most headphones. The variable 2V DC power supply can also measure DC current.
The AIO-AC presents a standard USB audio sound card interface and is compatible with most audio test software including APx Flex, LabVIEW, Soundcheck, and ARTA.
