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. 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 APx52x is a four channel version for those who require additional analog input channels.
