Elektrostatska referenca

An elektrostatički pokretač suspends a dijafragma thinner than a human hair između two perforated metal plates — the stators — and applies a high-napon bias charge to the dijafragma. When the audio signal is applied to the stators as a push-pull differential napon, the electrostatic field accelerates the dijafragma prema one stator and away from the other, producing sound with a linearity and speed that neither dynamic nor planarni magnetski drivers can approach. The dijafragma has virtually no mass. It ne store energy. It ne ring. It jednostavno follows the signal with a fidelity that makes every other transducer tehnologija sound like a mehanički approximation of music — because that is what they are.

The Electrostatic Reference uses a 108mm dijafragma of 1.35-micron Mylar film with zlato-sputtered electrodes. Zlato was odabran for its oksidacija otpor and uniform conductivity — kritičan svojstva when the electrode must održavati a perfectly even charge distribution preko its entire površina area. The stators are perforated čelik, kriogeno tretirani at -196°C to relieve rezidualni stress from the stamping proces and matched in pairs to a tolerancija of 0.01%. Stator matching at this preciznost osigurava that the push and pull forces on the dijafragma are identičan in magnitude, which eliminiše the even-order harmonic distorzija that plagues electrostatic slušalice built to looser tolerances. We are aware that some proizvođači match stators to 1%. We are also aware that 1% is one hundred times less precise than 0.01%. The arithmetic nije subtle.

The bias napon is supplied by a dedicated energizer unit — a separate kućište that must be placed unutar kabel reach of the slušalice and connected to AC mains power. The energizer sadrži a monokristalni bakar transformator wound u našem pogonu u Quitu, which converts the incoming AC to a stable 580V DC bias with manje od 0.3mV of ripple. Konvencionalni energizers use polycrystalline bakar transformatori, in which granice zrna između bakar kristali act as micro-resistors that modulate the bias napon at frequencies corresponding to the mehanički resonances of the transformator core. Single-kristal bakar nema granice zrna. The bias napon it proizvodi is, unutar the limits of our mjerenje oprema, perfectly smooth.

The ear chambers are lined with mu-metal — a nickel-iron alloy with exceptionally high magnetska permeabilnost that redirects vanjski elektromagnetska interferencija oko the driver umjesto allowing it to impinge on the dijafragma. The oklapanje pruža 80dB of EMI attenuation, which means that the elektromagnetski šum from your smartphone, your Wi-Fi router, and the switching power supplies in every other uređaj in your prostorija za slušanje is reduced by a factor of ten thousand prije it reaches the dijafragma. The slušalice connect to the energizer via a dedicated 5-pin kabel that is incompatible with every other slušalica pojačalo on the tržište. Ovo je by dizajn. If you could plug these into a standard pojačalo, you would, and then you would blame us for the rezultat.
