The QA490 is an acoustic tester for IEMs. The QA490 is designed for comparing "golden unit" IEMs to DUTs. This means the QA490 can validate the performance of a newly manufactured IEM before shipping, or the QA490 can be used to compare the performance of IEMs over time. That is, you can learn if there's been a shift in performance due to damage. 

The QA490 features a high-current OPA1622 opamp, tightly-spec'd MEMS mics, 10.5mm acoustic ear cups, and a switching network that allows the measurement for sensitivity, frequency response and impedance. A high-gain path relay path (0 or +12 dB, selectable via software) allows the generation of drive levels required for 600 ohm headsets. This ensures you can drive high-Z IEMs (typically 150 ohms) to levels required for accurate validation.
