By customer request: Loudspeaker production test suite
Audio Precision has launched a Loudspeaker Production Test suite, offering a new high bar in audio test quality for loudspeaker driver production test and final QA for integrated products such as soundbars, pro-audio powered speakers, smartphones and handsfree devices.
Audio Precision says that the features were requested by current customers because they want to use AP's hardware and intuitive software instead of sound-card based solutions. In less than one second, the Loudspeaker Production Test measurement returns multiple results: rub and buzz, impedance magnitude and phase, key Thiele-Small parameters, SPL, frequency response, phase, and distortion (either total or specific harmonics).
Polarity can be evaluated with the built in phase measurement, or by a separate half-second measurement. If required, air leak detection is measured in another half-second measurement. All normal APx functionality, such as floating limits based on a golden unit, smoothing, one-click automation and automated reporting are also available. The same hardware and software can measure speakers, power amplifiers and other electronics and APx's automation allows for faster line setup or adjustment as test needs change. Because the hardware is reliable and ships with an ISO:17025 accredited calibration, test stations have fewer problems and no time is spent questioning the accuracy of results.
There is a three year warranty and free technical support. In addition to the Loudspeaker Production Test suite, a new R&D suite has also been released. The new Impedance/ Thiele-Small measurement enables complex impedance and full Thiele-Small parameters. Waterfall (CSD) and polar plots have also been added. With this extended electro-acoustic functionality, APx is ideal for integrated devices: R&D groups working on different sections of a device (such as power amp, Bluetooth, HDMI, DSP and speakers) can share APx projects and results seamlessly, then send a single, lockable test sequence with limits and reports to manufacturing.
