AUDIO PRECISION APx525B Analog and Digital Audio Analyzer
The Audio Precision APx525B audio analyzers combines an award-winning user interface and legendary performance with a comprehensive range of modular I/O options. It 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, APx525B 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. Its modular systems allow you to select the interfaces and options that make sense for the work you do, covering the widest range of digital I/O in the industry.
The Audio Precision APx525B brings AP innovations such as one-click measurements, code-free automation and sophisticated reporting to every interface in every combination. 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. Combined with APx audio measurement software, the Audio Precision APx525B audio analyzers integrate power, flexibility and ease-of-use. Choose between Bench Mode for real-time visibility into device behavior across a variety of parameters, and Sequence Mode for fast production testing and automated measurements.
