Audio Precision has offered many different families and models of audio analyzer since 1985. All models remain under full support for a minimum of five years from their date of discontinuation. See the Service page for support definitions.
The 2700 Series was designed for audio engineers requiring high performance, low distortion and flexibility in their audio analyzer. The 2722’s true dual-domain architecture enabled extraordinary performance in measuring both analog and digital signals. 2700 Series “A” (APIB) instruments have an APIB (Audio Precision Interface Bus) connector and require Windows XP, or later versions, to run the AP Control Software. “G” instruments include the IEEE-488.2 GPIB interface and can also be controlled directly through GPIB.
