The Audio Precision’s System SYS-2722 is the newest generation of PC-controlled audio test and measurement instruments. The 2700 series continues to provide the unmatched distortion and noise performance required to test the latest advances in converter technology, while raising the bar with new 192k digital input and output capabilities.

In the SYS-2722 dual-domain architecture provides uncompromised performance for both analog and digital signals: the hardware generator and analyzer specifications surpass those of any digital configuration, while digital analysis techniques offer a wide array of high-speed, precise measurements for either domain. Cross-domain work can be accomplished using the best of both worlds.

• The unparalleled precision of a dedicated hardware instrument


• Fast instrument operation and powerful analysis under sophisticated control software.


• Programmatic control for high-speed automation.


• Serial digital interface testing.


• Flexible configuration options.


• A family of auxiliary instruments for specialized testing.


• AES3, IEC60958 (SPDIF) and PSIA input and output sample rates at 192 kHz.
