Audio Precision Showcases Key Audio Test Applications at Prolight+Sound 2016

Audio Precision, revealed its planned application demonstrations for Prolight+Sound 2016, one of the world’s premier events for professional media and entertainment, which runs from April 5-8 in Frankfurt, Germany. Planned application demonstrations during the show include enhanced electro-acoustic and production testing setups, testing Dante-enabled systems, and measuring high-performance amplifiers, ADCs and DACs.
An example of multiple sequences - in this case, for mic calibration, golden unit test and loudspeaker test - in a single APx500 project. This is one of the features added in Audio Precision's latest software release, being demonstrated at Prolight+Sound in Frankfurt.

Audio and electro-acoustic test within a manufacturing environment can present unique challenges for the test engineer. Audio Precision’s latest software release, v4.2, adds a dedicated production test mode that enables a test system administrator to create device-specific projects—for example, loudspeakers, headphones and microphones — then put the system into password-protected production mode. From that point on, system operators have a simplified interface that allows for project selection, test activation and report generation, but does not permit project modification or parameter changes. The new release also supports the creation of customizable sub-sequences for applications such as “golden unit” testing or microphone calibration.

In addition to multichannel, Ethernet-based, high-quality audio transport, many Dante-enabled devices also contain conventional analog and/or digital audio interfaces—as well as ADCs, DACs, or powered loudspeakers — all of which need to be tested through their Dante interface. AP’s Dante testing station will enable visitors to experience 8- or 16-channel testing of a Dante-enabled device via the ASIO client interface of an APx58x Series multichannel analyzer.

AP’s flagship analyzer, the APx555, offers audio developers previously unachievable insight into the behavior of their designs, unimpaired by noise or artifacts from the test system. Event attendees can witness first-hand the APx555’s performance—including typical residual THD+N of -120 dB — as it tests high-performance, commercially available amplifiers, ADCs and DACs.

“From technology designers pushing the boundaries of performance to the growing audio test needs of equipment manufacturers, international events such as ProLight+Sound play an integral part in AP engaging and helping engineers around the globe to overcome their measurement challenges,” says Spyros Lazaris, Audio Precision Vice President, Sales & Marketing

Since 1984, Audio Precision has offered high-performance audio analyzer instruments and applications to help engineers worldwide design and manufacture consumer, professional and industrial audio products. Attendees seeking to understand and solve measurement challenges should visit AP in Hall 4.1, Stand A20 for hands-on demonstrations of audio and electro-acoustic testing, and the accompanying expertise of AP’s technical staff. Prolight+Sound 2016 runs April 5-8 in Frankfurt am Main, Germany.
