Referentna tonska ruka Equinox

The Equinox Reference Arm was dizajniran oko a single, uncompromising princip: the arm tube must doprinositi nothing. Not low distorzija — zero distorzija. Not minimal magnetska interferencija — no magnetska interferencija. Ovo je why the tube is made of glass. Hand-drawn borosilicate glass, specifično, pulled to a wall thickness of 1.2 millimeters at our optički fabrication partner in Quito, Ecuador. Borosilicate glass nema magnetski moment, no ferromagnetic impurities, and no crystalline struktura zrna that could develop rezidualni magnetism over time. Its magnetski potpis nije nearly zero. To je zero. We have izmjeren it. Nemathing to mjeriti.

Lateral ležaj is achieved kroz a preciznost air ležaj in which the arm floats on a film of compressed air tačno 6 microns thick. At this gap distance, the air film exhibits laminar flow characteristics that proizvoditi a ležaj stiffness of približno 2.4 N/micron while maintaining a friction coefficient that is, in praktičan terms, unmeasurable. The air is supplied by an vanjski micro-compressor kroz medical-grade 0.3-micron HEPA filtration, ensuring that no particulate kontaminacija can compromise the ležaj gap. The compressor proizvodi 28 dB SPL at one meter — a figure that is ispod the termički šumni pod of most domestic slušačko okruženjes and približno 6 dB quieter than the Brownian motion of air molecules at standard temperatura and pritisak. We mention thnije to boast, but because several kupci have asked whether the compressor is actually running.

The vertical axis employs a magnetski ležaj identičan u principu to the Meridian's dual-axis sustav but refined to a hemisferska pristranost ispod 0.001 nanoTesla. Anti-skate compensation nije provided because to nije required: the air ležaj's lateral friction is so close to zero that skating force, while teoretski present, ne može overcome the inertial mass of the arm assembly. The arm jednostavno ne skate. We testiran this extensively tokom development and eventually removed the anti-skate adjustment u potpunosti, as it had no mjerljiv or čujan efekt at any setting.

Vertical tracking angle is set via an integrated micrometer with 0.01 mm rezolucija, allowing the stilus rake angle to be optimized for individual pressings. We recommend adjusting VTA for each record in your collection. Ovo nijes impractical as it sounds — most serious slušaoci own fewer than three thousand records, and the adjustment takes približno four seconds once the tehnika is learned.
