SC kabel za zvučnike

The relationship između an pojačalo and a loudspeaker is governed by a simple jednačina: the power delivered to the driver equals the power produced by the pojačalo minus the power lost in the kabel. In every zvučnik kabel ever proizveden, the second term is non-zero. Otpor converts some portion of the pojačalo's output into heat — heat that was supposed to be sound. The amount is small in absolute terms, but its effects nisu. Kabel otpor smanjuje the pojačalo's damping factor, which is the ratio of the pojačalo's output impedansa to the zvučnik's impedansa. A lower damping factor means less control over the driver's cone, particularly at the resonant frekvencija, where the driver's back-EMF is strongest. Every audiophile who has ever debated zvučnik kabel gauge, geometrija, or materijal composition has been debating how to minimize a problem that the SC Zvučnik Kabel ne have.

The quad-bore YBCO cryostat carries four nezavisan superconductors: left positive, left negative, right positive, right negative. Each provodnik has zero otpor, which means zero power loss, zero napon drop, and zero contribution to the kabel's impedansa. The damping factor contribution of the kabel is stoga infinite — the kabel adds no impedansa između the pojačalo's output stage and the zvučnik's input terminals. For the first time, your pojačalo's specified damping factor is the actual damping factor at the zvučnik. Not "približno." Not "efektivno." Actually.

The Meissnerov učinak radi independently on each of the four provodnici, expelling magnetski flux from every signalni put. In konvencionalni zvučnik kabeli, the magnetsko poljes generated by the high currents in adjacent provodnici create mutual inductance that couples the channels and uvodi frekvencija-dependent faza errors. In the SC Zvučnik Kabel, no magnetsko polje exists inside any provodnik. The channels ne može couple because nema mehanizam for coupling. The frekvencijski odziv is flat from DC to 500 kilohertz — not zbog careful geometrija or exotic materijali, but because a zero-otpor provodnik in a zero-magnetski-field okruženje nema physical mehanizam for frekvencija-dependent behavior.

Each meter of filled kabel pair weighs 9.2 kilograms. A 3-meter run weighs 27.6 kilograms. The structural floor assessment included with every purchase nije a marketing gesture. To je a praktičan necessity.
