Audio Precision shows new APx515 analyzer

The new audio analyzer from Audio Precision is optimized for fast, accurate production testing.
Initial demand for the new APx515 has far exceeded Audio Precision’s expectations.

At the recent AES Convention in London, Audio Precision introduced the APx515, a new two-channel audio analyzer optimized for production test applications at a reasonable price. Despite its low cost, APx515 still has excellent performance, sitting just below the APx525, whose lower THD+N and chip-level connectivity options make it more appropriate for R&D. In terms of specifications, the new APx515 offers a typical THD+N of -106dB, 24-bit FFTs and 192k digital I/O.

With the high-speed test option, the APx515 can make all the key audio measurements in less than 3s. In stand-alone mode, test sequences are created by selecting from a list of common audio measurements and saving to a project file. On an automated line, a master application can control the APx515 directly using the .NET API or APx LabVIEW driver. In either mode, the operator can control APx with a keyboard, footswitch or barcode scanner, or the system can be totally automated. Graphical reports can be generated via Word templates or by exporting data into a database.

Because all APx audio analyzers use the same software, tests and results are easier across any enterprise situation, including vendors, R&D and production facilities anywhere in the world. For example, a production test sequence created on an APx525 can be e-mailed to a manufacturing facility using an APx515, which will run the project natively. Performing quality assurance on the production line, the APx515 operator can save a recording of the actual output of a device under test and e-mail it (along with the 515’s settings) in a single project to engineering for further analysis.

The APx515 includes a three-year warranty and ISO17025-accredited calibration. Orders and being accepted now, and the first will ship APx515 in August 2010.
