Audio Precision APx517B acoustic analyser

Audio Precision’s APx517B acoustic analyser is specifically designed, configured and built for the production-line testing of speakers, microphones, headphones, headsets and consumer electronics incorporating speakers and microphones.

On a production line, any time spent setting up a new test system, calibrating a system for a new shift or reconfiguring a system for a change in DUT (device under test) is effectively a ‘line down’ situation. As an integrated system combining audio analyser (signal generation and acquisition), power amplifier, headphone amplifier and microphone power supply, along with any required digital interface such as Bluetooth, the APx517B has the power to reduce set-up and reconfiguration time by eliminating multiple individual components and their associated cabling. Additionally, the device is delivered with an accredited ISO/IEC 17025 calibration.

In its base configuration, the product is a ready-to-go system for measuring analog speakers, microphones, headphones or headsets. For digital devices, it has a module slot for the addition of a single APx digital interface module, such as Bluetooth, PDM or HDMI. On the software side, a standard system provides a core set of measurements and functionality to allow out-of-the-box, fundamental test of acoustic devices: file analysis, sequence mode, input signal monitors (including FFT monitor), level and gain, THD+N, loudspeaker product test (including rub and buzz), stepped frequency sweep, pass/fail and signal acquisition measurement.
