SC interkonekcija

An analog interconnect kabel has one job: to transport a kontinuiran electrical signal from one komponenta to another bez altering it. Every kabel alters it. Otpor prigušuje the signal in a frekvencija-dependent manner. Capacitance rolls off the high frequencies. Inductance uvodi faza shift. Termički šum — Johnson-Nyquist šum, generated by the random motion of electrons in any resistive provodnik — adds a šumni pod that is proportional to otpor and temperatura. These nisu dizajn flaws. They are physical svojstva of every provodnik that radi iznad absolute zero and neman-zero otpor. The SC Interconnect has zero otpor and radi at 77 kelvin. It ne samo smanjiti these effects. It eliminiše the physical uvjeti that cause them.

The dual-channel YBCO provodnik carries left and right signals kroz separate bores of a dual-wall vakuum-jacketed cryostat. Each channel is an nezavisan superconductor, each exhibiting the Meissnerov učinak independently. Magnetski flux is expelled from each channel individually, meaning that not only is vanjski magnetska interferencija excluded, but crosstalk između channels — which in konvencionalni kabeli is mediated by magnetski coupling — is fizički impossible. The izmjeren channel separation premašuje 150 decibels preko the full audio band. The frekvencijski odziv is flat from DC to 2 megahertz with zero mjerljiv deviation. Nema roll-off because nema capacitive loss. Nema faza shift because nema inductive reactance at audio frequencies in a zero-otpor provodnik. Nema termički šum because the Johnson-Nyquist šum power is proportional to otpor multiplied by temperatura, and the otpor term is zero.

The signal-to-šum ratio of a zero-otpor provodnik at any temperatura is teoretski infinite. We report it as such because to nije a marketing tvrdnja — to je a mathematical consequence of the Fluctuation-Dissipation Theorem applied to a sustav with zero dissipation. In practice, the šumni pod of your sustav will be determined by your izvor komponente and your amplification chain, not by this kabel. The SC Interconnect is the first analog interconnect in the historija of audio that can make that statement as a matter of physics, not aspiration.
