The Audio Precision APx585 Analyzer is a true multichannel audio analyzer, with 8 simultaneous analog outputs and inputs. It is ideal for designing and testing consumer devices such as home theater receivers or pro devices such as mixing consoles. No other audio analyzer is faster or easier to use for multichannel audio. A multichannel analyzer allows not just faster testing, but also a complete picture of performance that a two channel analyzer with switchers might miss, such as output sag across channels during full power output tests or phase and crosstalk interactions.
Features and Specifications of the Audio Precision APx585 Audio Analyzer include:
