AD2504 Audio Analyzer with analog 2 outputs and 4 inputs, and can adapt to the needs of multi-channel production line testing

Super scalable, flexible configuration

AD2504 is a basic test instrument in the AD2000 series audio analyzers. It expands two analog input interfaces on the basis of AD2502. It has the characteristics of analog 2 outputs and 4 inputs, and can adapt to the needs of multi-channel production line testing. The maximum input voltage of the analyzer is up to 230Vpk, and the bandwidth is >90kHz.

In addition to the standard dual-channel analog input port, AD2504 can also be equipped with various modules such as DSIO, PDM, HDMI, BT DUO and digital interfaces.
