Abstract
Abstract A cable interconnection for an audio component system includes a first cable and a second cable. The first cable has a pair of first conductors, each of the first conductors are adapted to make an electrical connection between a source positive terminal and a load positive terminal of a signal source and load, respectively. The second cable has a trio of second conductors. A first one and a second one of the trio of second conductors, are each adapted to make an electrical connection between a source negative terminal and a load negative terminal of the source and load. A third one of the trio of second conductors is adapted to be coupled electrically only to the load negative terminal. The third one of the second conductors extends substantially the full length of the second cable. A rheostat may be provided to be coupled electrically in series between the third one of the second conductors and the load negative terminal. Adjustment of the rheostat provides for a variable length of the unterminated second conductor. Instead of a rheostat, a switch may be provided which selectively couples the unterminated conductor to or uncouples the unterminated conductor from the load negative terminal.
