Audio Analyzer A5 replace AP525

Audio analyzer A5

A5 is a high-performance analog 2-channel audio analyzer , fully benchmarking with AP company APx525. In addition to having ultra-high system performance, it also provides a series of testing plugins to expand testing capabilities, and supports multiple digital interfaces (BT, I2S, HDMI, PDM, etc.). It is a testing equipment for the development stage of consumer audio and automotive electronics and other audio and video products.

With the continuous upgrading and replacement of audio products and Bluetooth technology, early audio analyzers can no longer meet the current test needs in some functions, such as small output and input amplitude, and single codecs supported by Bluetooth. In response to the above problems, we designed and developed the A5 audio analyzer, which has ultra-high system performance: typical THD+N -108dB, maximum input 300Vrms (balanced), analog output amplitude 21Vrms. Support a variety of Bluetooth codecs, such as: SBC, APTX, APTX-LL, aptX-HD, AAC, LHDC (HWA), etc., DSIO option supports higher sampling rate than before, and adds PDM interface options to expand the application range of the instrument, A5 basically meets the audio performance test of all current audio products.
