The APx500 Series is a dedicated multichannel audio analyzer that combines a next generation user interface with AP’s legendary commitment to performance.
Now available in an 8 or 16 channel configuration, the APx is capable of taking 14 measurements in as fast as 7 seconds, automatically generating a report of results and saving all test settings in a single, sharable project file.
- One-click measurements and saveable sequences
- Real-time signal monitors including residual THD+N in oscilloscope view and one million point FFT
- Dolby/ DTS confidence testing, multitone analyzer, input regulation, and CEA-2006 & EIA/CEA-490-A measurements.
- Multiple connectiviy options: 8 or 16 channel analog balanced & unbalanced; digital HDMI, SPDIF, AES/EBU and TOSLINK,

Faster, easier multichannel test |
When AP’s engineers began designing the APx Series, they saw that a new platform was needed to maintain the innovation curve defined by the System One in 1984 and the System Two in 1992.
The new architecture had to have a modern, context-sensitive interface so users could get to the measurements & settings they needed with a mouse click. It had to take advantage of today’s computing power, allowing more measurements to be derived from a single acquisition and allowing easy upgrades of features via online software updates. It had to be flexible enough to serve the needs of R&D and production test users without compromising performance.
Above all it had to be easy to use and faster than anything on the market.
Accredited calibration to ISO17025 standard
|
Every APx is calibrated before it leaves the factory, so that you know your measurements are accurate and your instrument meets the most stringent Quality System Requirements in the industry. |
| Audio Precision is accredited by A2LA, by the American Association for Laboratory Accreditation, to perform calibrations at its Calibration Lab in Beaverton, Oregon. The company is the only audio analyzer manufacturer to perform factory-based ISO17025 calibration. |
