Abstract

This invention discloses an anti-interference audio signal isolation distributor, belonging to the field of audio signal processing technology. It aims to solve the problem that traditional audio signal isolation distributors are unable to effectively block external electromagnetic interference. The distributor includes a housing and its interface, as well as a signal distribution module, an audio isolation transformer, an impedance matching module, and a frequency response characteristic module. The signal distribution module is used to distribute one signal to multiple mixing consoles, and has direct output and isolated output. The signal distribution module also includes a microprocessor-controlled intelligent signal distribution switching unit, which automatically adjusts the signal distribution path and parameters according to the type and number of mixing consoles connected and the real-time signal transmission status. This invention significantly improves the purity and stability of audio signal transmission, meeting the high sound quality requirements of professional audio production, large-scale performances, and other fields.
