Personal computer audio interface device and method of using the same

An interface system for interconnecting an audio output port of a personal computer to first and second audio input ports of a home stereo system, each of said first and second audio input ports being characterized by a substantially higher input impedance than an output impedance of said audio output port, comprising:

• a housing;
• a first impedance transformer disposed within said housing for improving an impedance match between said audio output port and said first audio input port;
• a second impedance transformer disposed within said housing for improving an impedance match between said audio output port and said second audio input port;
• a multiple conductor elongated cable having a first coupling device at one end thereof and a second coupling device at another end thereof, said first and second coupling devices being dimensioned and arranged to establish respective electric signal paths through said cable by electrically interconnecting said audio output port and corresponding low impedance windings of said first and second impedance transformers;
• and
• third and fourth coupling devices mounted on said housing, said third and fourth coupling devices being dimensioned and arranged to accommodate electrical connections between corresponding high impedance windings of said first and second impedance transformers and the first and second audio input ports of said home stereo system.
