ABSTRACT:
A circuit and method for improving the accuracy of an electrical signal communicated between electrical devices, particularly audio equipment, is disclosed herein. The apparatus includes a circuit that biases a cable to a biased voltage. A signal, analog or digital, is communicated through the biased cable. The present invention has applicability in any cable that is used to send electrical signals between electrical equipment, and particularly equipment for reproducing audio signals, such as high fidelity stereo equipment in order to more closely reproduce the musical qualities of the original recordings.
