Circuitry cancelling potential differences and for signal linearisation

摘要

The circuitry is used in high-quality sound recording and playback systems. Even in these systems, the ground wires have a finite resistance. The currents flowing through them therefore generate voltages, albeit of a very low level. Potential differences thus occur over the length of the ground wires. This impairs playback. To cancel or at least minimise these potential differences, the invention provides that all ground wires have a lower specific resistance than the signal wires and the same resistance as one another.
