Passive audio/video component unbalanced network to balanced network adapter

A passive adapter for reducing distortions originating from a balanced link between an audio/video transmitter connected to a first ground and an audio/video receiver connected to a second ground, the passive adapter comprising:

• a first unbalanced video terminal;
• a second unbalanced video terminal;
• a third unbalanced video terminal;
• a first unbalanced audio terminal;
• a second unbalanced audio terminal;
• a first balanced choke having a first end and a second end;
• a first balun transformer having a first input operatively connected to the first unbalanced video terminal, a first output operatively connected to the first end of the first balanced choke and a second output operatively connected to the second end of the first balanced choke;
• a second balanced choke having a first end and a second end;
• a second balun transformer having a first input connected to the second unbalanced video terminal, a first output operatively connected to the first end of the second balanced choke and a second output operatively connected to the second end of the second balanced choke;
• a third balun transformer having a first input operatively connected to the third unbalanced video terminal, a first output operatively connected to the first balanced choke at a given location and a second output operatively connected to the second choke at a given location;
• a first audio transformer having a first input operatively connected to the first unbalanced audio terminal, a first output and a second output;
• a second audio transformer having a first input operatively connected to the second unbalanced audio terminal, a first output and a second output, said second output of said second audio transformer being operatively connected to said second output of said first audio transformer;
