Key Features and Functions 

The APx52x Series of audio analyzers combines our award-winning user interface and legendary performance with a comprehensive range of modular I/O options. The APx52x Series brings AP innovations such as one-click measurements, code-free automation and sophisticated reporting to every interface in every combination.

  • 2 analog input channels (APx525)
  • 4 analog input channels (APx526)
  • AES/SPDIF digital I/O
  • Typical THD+N < -110 dB [with AG52 option]
  • > 1 MHz bandwidth @ 24 bits on two channels [with BW52 option]
  • 1.2 M point FFTs
  • Use Sequence Mode or new Bench Mode for ultimate flexibility and control
  • Powerful automation and sophisticated reporting
  • Support for the complete range of APx digital I/O options

APx52x B Series Full Specifications

SYSTEM REQUIREMENTS
• Microsoft Windows 10 (64-bit) operating system.
• USB 2.0 or USB 3.0. Two are required for optional switcher or DCX-127 use.
• Intel i5 or better processor running at a clock speed of at least 2.5 GHz. AMD processors with similar specifications are also supported.
• At least 8 GB RAM. 16 GB is highly recommended
internet connection or CD-ROM drive (to access APx500 software for installation).
• At least 1.5 GB of free hard disk space. An SSD for the operating system drive is recommended.
• A color monitor and video card with at least SXGA (1280 X 1024) video graphics support. Video resolution of 1900 x 1080 or greater is recommended.
• More detailed information is available on our AP Software and Windows Compatibility chart

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.
