The Echo AIO-S2 is a 4-channel acoustic interface designed for production-line testing and QA/QC verification. Combining four 10W amplifier outputs and four mic/line analog inputs in a single unit, the AIO-S2 is an integrated, cost-effective, and reliable high-throughput audio test solution. Two of the amplifier outputs include a 0.1 Ohm sense resistor to facilitate 2 channel impedance measurements. Four additional line inputs are dedicated to voltage monitoring (VMON) and current monitoring (IMON)
for each impedance measurement output.
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).
The AIO-S2 presents a standard USB audio sound card interface and is compatible with most audio test software including APx Flex, LabVIEW, Soundcheck, and ARTA.
