Audio Precision APX555

RENT AUDIO PRECISION APx555 Audio Analyzer (call for RENTAL availability)

The Audio Precision APx555 Analyzer is ais 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 surpasses the performance of the AP System 2 Cascade (2700 series).

With a typical residual THD+N of -120 dB and up to 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.

The Audio Precision APx555 has two balanced and two unbalanced analog inputs and outputs plus 192K digital inputs and outputs via AES/EBU, TOSLINK and SPDIF. Additionally, I/O may be expanded with optional Digital Serial, HDMI with ARC, PDM 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 the APx52x Series and APx58x Series Audio Analyzers.

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.

With the AP APx555, you can 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.
