Industrial Automatic Control Systems and Controllers Annotation << Back Microcontroller-Based Automation Module for Comparative Headphones Testing with the Connection Integrity Protection Korotich A.V., Lebedev A.A. The developed device is intended for high-quality reproduction of the audio-information from solid-state carriers (flash cards of format MMC/SD) on eight independent stereo headphones. Reproduction is carried out on in advance set algorithm and according to actions of the operator (user). In the course of work continuous control of integrity of connection of phones by measurement of their electric characteristics (indirect measurement of resistance) is made. The device is applied as a part of the stand of comparative testing of stereo headphones in trading floors, and as in offices of learning of foreign languages. Key words: headphones, audio playback.
