A two chassis system
The Helix One Mk3 Vacuum turntable system consists of the main turntable chassis that sits on its powerbase and a second vacuum system chassis (box).
The faceplate of the Vacuum box can be ordered in a black finish or in the chosen finish of the turntable so it matches the turntable.
What does a vacuum hold-down system do?
A vacuum turntable uses a gentle suction beneath the record to draw the vinyl firmly and uniformly onto the platter surface. For this to work, the platter must have a special design: an air channel or pathway and a sealing mat or lip around the edge that allows the vacuum to create a seal under the record. Once the vacuum is engaged, the vinyl becomes effectively part of the platter — fully “coupled” and flat, eliminating air gaps and ensuring full-surface contact. This pressure is evenly spread across the whole disc, not just at the label/spindle area (as with a clamp) or edge (as with some stabiliser rings). Aside from presenting a flat vinyl record, the vinyl and the platter present as one ‘effective mass’, which has sonic benefits.
