Product Overview

RENT AUDIO PRECISION APX525 Audio Analyzer (Call for Availability)


The Audio Precision APx525 audio analyzers combines an award-winning user interface and legendary performance with a comprehensive range of modular I/O options. The APx525 ships with two channels of analog I/O and our Digital Interface Option (DIO) with AES/SPDIF digital inputs and outputs, and includes ASIO capability. If you need more than that, APx525 is ready with a full range of choices, from additional channels of analog to a chip-level digital serial interface (DSIO), HDMI+ARC, PDM (Pulse Density Modulation) or Bluetooth® wireless technology with built-in radio.

With its redesigned software platform, the powerful Audio Precision APx525 Audio Analyzer Series provides never-before-seen flexibility and usability. Across all measurements, the APx UI is fast and intuitive. Just click to select a measurement, then click to add a filter. Drag limits to set pass/fail points right on the results graph. Effortlessly specify computations for derived results. The APx generator can output steady tones, twin tones, sweeps, chirps, multitones or play WAV files as arbitrary waveforms. Repetitive bench tests and production testing can easily be automated with the built-in measurement sequencer and saved as a project that can be used with the Audio Precision APx525 analyzer.

• 2 analog input channels
