Audio Precision SYS-2722 音頻分析儀
The Audio Precision 2722 Audio Analyzer is the flagship model of Audio Precision’s award-winning PC-controlled audio analyzers, long the recognized worldwide standard for the design and test of audio equipment. The fullfeatured SYS-2722 provides the unmatched distortion and noise performance required to test the latest advances in converter technology, combined with 192k digital input and output capabilities.
The AP SYS-2722 features true dual domain architecture which enables uncompromised measurement of 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 precise, high-speed measurement techniques for either domain. Cross-domain work can be accomplished using the best of both worlds.
