The APx52x Series of audio analyzers combines an 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
• 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

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.

Need higher analog performance? With the BW52 enhanced analog bandwidth option installed, you can make a million-point FFT spectrum acquisition at 24 bits, across a bandwidth of DC to over 1 MHz on two channels. And with the AG52 enhanced analog generator option, typical system THD+N is as low as 110 dB.

The Audio Precision APX525 is fully tested and refurbished in our in-house ISO9001 calibration laboratory. We supply manuals, accessories, full warranty and a free-of-charge Certificate of Conformity. We can also provide the Audio Precision APX525 with a fresh calibration for a small additional charge.
