Abstract: An audio splitter is often used with a mixer or other source to take left and right stereo inputs into spaced apart input jacks of a housing and output at least four separate outputs at spaced apart output jacks on the housing for communicating those inputs to the outputs, often for use by cameras. More sophisticated versions include the ability to receive a timecode as an input at a separate jack and then output the timecode as an output at each of the output jacks. Still further sophisticated versions receive a return signal at each of the output jacks which can be monitored or utilized for further processing.
