A culmination of 30 years' experience making test equipment recognized as the standard of the audio industry, the APx555 is a two-channel audio analyzer without compromise. Developed for R&D engineers and production technicians who need the highest possible performance, a broad range of digital I/O options and fast, intuitive software, the APx555 is the new standard for audio analyzers.

The perfect evolution of audio analysis

The APx555 delivers performance, flexibility and versatility.

Unprecedented performance
With a typical residual THD+N of -120 dB and over 1 MHz bandwidth, the APx555 surpasses the analog performance of all other audio analyzers, including a 5 dB improvement compared to our 2700 Series analyzer. Add to this FFTs of 1.2 million points and full 24-bit resolution, and you have performance unmatched by any other instrument.

Maximum versatility in I/O
APx555 has two balanced and two unbalanced analog inputs and outputs plus 216k digital inputs and outputs via AES/EBU, TOSLINK and SPDIF. Additionally, I/O may be expanded with optional Digital SerialHDMI with ARCPDM and Bluetooth modules. A new Advanced Master Clock (AMC) module handles input and output clock signals to synchronize the APx555 with external equipment (or vice versa), and the AMC also enables jitter generation and analysis. AMC is standard with the APx555 and is an option for theAPx52x Series and APx58x Series Audio Analyzers.

Software flexbility
With its redesigned software platform, the powerful APx Audio Analyzer Series provides never-before-seen flexibility and usability. The bold new interface offers users two easy-to-use modes. Choose between Sequence Mode for fast production testing and automated measurements, and Bench Mode for real-time visibility into device behavior across a variety of parameters.

Made to measure for power amp designers
Measure continuous maximum output and peak maximum output automatically, DIM measurements, view power spectrum graphs with a regulated frequency sweep and take other measurements as specified by the CEA-2006 and CEA-490A standards. In addition to conventional balanced common mode rejection measurements, APx555 also enables CMRR measurements in accordance with IEC60268 section 14.15.1.

Sharing projects
All settings for a test are saved in a single project file that’s small enough to email, making it easy to replicate test setups between R&D and production facilities anywhere in the world. Project files are compatible with all APx instruments and each project is self-contained, so there’s never any worry about dependencies or broken links.

Reporting results
For customers, contract manufacturers or management, APx automatically generates rich graphic reports, with highlighted pass / fail limits and options to export as PDF, HTML, Excel or text.

SYSTEM REQUIREMENTS
  • PC with 2 GHz or faster multi-core processor (2 or more cores)
    Note: the Intel Atom dual-core processor does not have sufficient performance to run APx software.
  • 2 GB or more RAM (4 GB or more recommended for Windows 7/8).
  • Microsoft Windows XP (32-bit, SP 2 or later), Windows Vista (32-bit), Windows 7 (32- or 64-bit), Windows 8 (32- or 64-bit).
NOTES
  • System performance is sensitive to processor speed; faster processors will yield faster results.
  • APx500 is data intensive and it is recommended that other data-intensive applications not be run concurrently. This includes Audio Precision AP2700, APWIN or ATS.
  • We recommend and support the following specific editions of Microsoft Windows: XP Professional SP2 and SP3, Vista Business and Ultimate, Windows 7 Professional and Ultimate (32- and 64- bit), Windows 8 Pro and Enterprise (32- and 64-bit).
