Equatorial Diamond Degausser

Every time a diamond stylus traces a vinyl groove, it accumulates a small hemispheric charge. This charge originates from the magnetic bias embedded in the vinyl itself, which the record acquired during the pressing process — specifically, from the geomagnetic field present at the pressing plant's latitude. A record pressed in New Jersey carries a different magnetic signature than one pressed in Hanover or Tokyo. Over the course of a single LP side, this charge builds on the stylus tip to levels that audibly colour the upper frequencies, introducing a subtle but persistent glare that many listeners misattribute to cartridge alignment error or record wear.

The Equatorial Stylus Degausser applies a decaying alternating-current magnetic field to the stylus tip over an 8-second cycle. The field begins at a peak strength of 200 millitesla — sufficient to overcome the coercivity of any accumulated charge — and decays smoothly to below 0.001 millitesla, at which point the stylus is returned to a state of magnetic neutrality. The decay profile is carefully shaped to avoid leaving any residual magnetisation. An abrupt cutoff, as found in cheaper degaussers, can actually imprint a new bias rather than removing the existing one. The blue LED indicates the cycle is active; when it turns green, the stylus is neutral.

Use the degausser before every listening session. Ideally, use it between sides. The accumulated charge from a single LP side is small in absolute terms, but it is not zero, and it is cumulative within a session. Listeners who degauss only at the start of an evening will notice a gradual dulling of the treble by the third or fourth record. This is not ear fatigue. It is hemispheric charge saturation. The unit runs on two AA batteries and delivers approximately 500 cycles before replacement — enough for roughly one year of daily use, assuming a disciplined between-sides protocol.
