Patent ID: 8706273

Claim:
An apparatus for conveying audio signals from an input locus to an output locus remote from said input locus; the apparatus comprising: (a) a multi-pin unit configured for receiving at least three signal paths at said input locus; said at least three signal paths including at least two audio signal paths for conveying said audio signals and at least one ground path; (b) at least one cable unit coupled with said multi-pin unit; said at least one cable unit substantially spanning an interval between said multi-pin unit and said output locus; said at least one cable unit presenting said at least three signal paths at said output locus; (c) a connector pin unit coupled with said at least one cable unit at said output locus; said connector pin unit presenting said at least three signal paths in a single-pin configuration; and (d) a filter unit coupled with said at least one cable unit; said filter unit comprising two filter circuits that each include a resistor for filtering at least one predetermined bandwidth of the electromagnetic spectrum from said at least two audio signal paths, and wherein said ground path is continuous from said multi-pin unit to said connector pin unit.
