The Echo AIO-SA is a multichannel acoustic interface designed for production-line testing and QA/QC verification. Combining four 10W amplifier outputs and six mic/line analog inputs in a single unit, the AIO-SA is an integrated, cost-effective, and reliable high-throughput audio test solution. One of the amplifier outputs includes a 0.1 ohm sense resistor to facilitate impedance measurements. Two additional line inputs are dedicated to voltage monitoring (VMON) and current monitoring (IMON) for impedance measurements.

Echo AIO-SA Audio Interface


The Echo AIO-SA is a multichannel acoustic interface designed for production-line testing and QA/QC verification. Combining four 10W amplifier outputs and six mic/line analog inputs in a single unit, the AIO-SA is an integrated, cost-effective, and reliable high-throughput audio test solution. One of the amplifier outputs includes a 0.1 ohm sense resistor to facilitate impedance measurements. Two additional line inputs are dedicated to voltage monitoring (VMON) and current monitoring (IMON) for impedance measurements.

Each analog 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).

The AIO-SA presents a standard USB audio sound card interface and is compatible with most audio test software including APx Flex, LabVIEW, Soundcheck, and ARTA.Ω
