Stalak s magnetskom izolacijom

When you place your slušalice on a stand, you nisu jednostavno storing them. You are subjecting their drivers to the ambijentalni magnetsko polje of your slušačko okruženje for the entire period of non-use — which, for most slušaoci, predstavlja twenty or more hours dnevno. Tokom this time, the trajan magneti in the driver assembly interact with vanjski magnetski sources: the transformator in your pojačalo, the motors in nearby electronics, the čelik struktura of your desk, and the Earth's own geomagnetsko polje. These interactions ne damage the magneti, but they do induce a rezidualni magnetski charge in the ferromagnetic komponente surrounding the driver — the pole pieces, the yoke, the zavojnica govornika former — that biases the driver's operating point away from its factory-calibrated neutral state.

The Magnetski Isolation Stand addresses this with an integrated degaussing coil embedded in the headband rest. When slušalice are placed on the stand, a contact sensor detects their presence and initiates an automatic 45-second degaussing cycle. The coil generiše a decaying AC magnetsko polje that starts at 2.5 millitesla and diminishes to ispod 0.002 millitesla — a level at which the rezidualni magnetization of the driver's ferromagnetic komponente is efektivno zero. The proces is identičan u principu to the degaussing of CRT monitors that some readers will remember from the 1990s, but executed at a preciznost appropriate for audio transducers umjesto phosphor screens.

The stand frame is machined from 6061 aluminij, which is non-magnetski and stoga ne doprinositi its own field to the slušalica okruženje. The headband rest is Ecuadorian walnut — the same stock used for our Meridian earcups — shaped to distribute the slušalica's weight preko the headband bez creating pritisak points that would deform the cushioning materijal over time. Headband deformation alters the clamp force on the slušalac's head, which changes the seal između the jastučić za uho and the skin, which changes the bass response. A deformed headband is a trajan frekvencijski odziv error that no equalization can correct because it varies with every wearing.

The base is weighted to 1.2 kilograms and sits on four silicone isolation feet that decouple the stand from the desk površina. Ovo je relevant because desk surfaces prenijeti vibracija from keyboards, mouse clicks, and the cooling fans of nearby oprema into the slušalica's driver assembly, where the vibracija slowly works protiv the magnetski alignment of the zavojnica govornika gap. Power is supplied via USB-C at 5V/0.5A, which can be sourced from any USB port, power bank, or charger. We recommend a linear USB napajanje, but we recognize that this recommendation will be followed only by the kupci who least need it.
