The Audio Test Interface is a high-precision, multi-channel measurement device designed for both acoustic R&D and production line testing. It integrates 10 analog input channels (including 2 DC channels) and 8 analog output channels (including 2 amplifier outputs), covering a full bandwidth from DC to 80 kHz. This all-in-one solution handles signal excitation, response acquisition, and amplifier driving, simplifying the testing chain and improving system integration and deployment efficiency. It is suitable for various acoustic testing scenarios.
