This is an Audio Precision System One (SYS-22A) Audio Analyzer.
The unit is fully functional and in very clean cosmetic condition, the fan carbon filter has been replaced with a brand new carbon filter unit recently, and has previously had a full recapping of electrolytic capacitors done to the entire unit with Nichicon capacitors. You can see picture of removed old caps in the photos selection.
This analyzer works perfectly and is in spec and runs flawlessly with windows 10 or 11 and under other windows OS. We are currently running the latest version of APWIN 2.24 with Duke Aguiar’s USB Conversion Cable on windows 11, the cable can be purchased on eBay or direct from him. Duke is an ex employee of audio precision and is tremendous help with these older system on and two units.
We recently updated to a System 27 so we no longer have room on our bench or need this System One. This unit is a workhorse for those in need of accurate industry proven and accepted measurement tool for audio designers. The specs on these older AP units are as good as the higher end APX series which currently cost up to $30,000., and better then ATS-2, APX-515 and 516 series. And we the modern USB conversion cables being available the past a few years their test capabilities are not only still relevant but extremely affordable to achieve compared to the newer generation AP units.
This unit is in full calibration and passes all tests with flying colors. Please refer to the youtube link for full video of the self test process showing the unit pass all the tests.

Again USB cable can be purchased separately from Duke on eBay Or direct. And is not included, we are keeping our USB cable and are using it with out system 27.
The analyzer is designed for testing and analyzing audio signals with precision and accuracy. It is a reliable tool for professionals in the audio industry, providing detailed data acquisition capabilities for various applications such as testing audio equipment and systems.
SYS-22A
System One analog domain test set: generates and analyzes all signals via analog hardware. Key analog generator specifications include:
Distortion residual specification of -106 dB and flatness of +0.03 dB over a 20 kHz bandwidth. Analog analyzer specs feature residual noise of less than 1.5 microvolt (-114 dBu), flatness of $0.03 dB, and analyzer THD + N of -100 dB (0.001%).
With this analyzer you can Measures amplitude, power, level, ratio, crosstalk, phase, bandpass, , frequency response, THD+N, signal to noise ratio, noise and optionally IMD and wow & flutter.
