Bidirectional, variable-impedance instrument-level to professional-level audio interface with signal splitters and balanced DC power

摘要

An audio frequency variable-impedance instrument-level to professional-level audio interface with balanced DC power, comprising a unique arrangement of electronic elements, consisting of the musical instrument-level signal splitter with professional-level audio output interface 10, the professional-level signal splitter to instrument-level interface 12 and the power supply with regulation, innovative new DC balancing and power distribution 14. The innovation of balanced DC power effectively cancels the unwanted power supply noise on professional audio electronics giving greatly improved distortion and lower noise specifications over previous designs.
