With its vacuum hold-down system and ultra-precise motor control, it delivers unmatched realism and stability in vinyl playback.\u003c\/p\u003e\n\u003c!-- TABS --\u003e\n\u003ch5\u003eOVERVIEW\u003c\/h5\u003e\n\u003cp\u003eThe Helix One Mk3 has earned a reputation as an absolute reference turntable, despite not offering a vacuum system and has been frequently compared favorably in reviews to other turntables at the same pricing level which feature vacuum. For many owners, the vacuum system may be deemed to be unnecessary. However, for those customers who demand a vacuum system for the benefits that it gives and desire to have that ‘ultimate’ specification of a Döhmann turntable, the Helix One Mk3 Vacuum sets a new benchmark in audio playback. The vacuum system creates suction and turns itself off just as the stylus touches the grooves. There’s no pump action during replay at all and even if the system experienced a loss of suction which required the pump to activate, it is designed in a way that its operation is silent and decoupled from any aspect of the system that may affect the sonic performance. Furthermore, the virtual o-ring technology results in absolutely no influence of platter inertia whatsoever, the vacuum system contributes no influence on the carefully engineered platter \u0026amp; bearing systems. This level of performance is simply unprecedented.\u003c\/p\u003e\n\u003ch5\u003eFEATURES\u003c\/h5\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDöhmann vacuum hold-down system featuring Rotary Feedthrough Technology\u003c\/li\u003e\n\u003cli\u003eFacilities for two tonearms\u003c\/li\u003e\n\u003cli\u003eCustom designed Swiss-manufactured motor\u003c\/li\u003e\n\u003cli\u003ePowerBase with new advanced DC power supply circuitry\u003c\/li\u003e\n\u003cli\u003eAdvanced Composite Armboards\u003c\/li\u003e\n\u003cli\u003eMicro Signal Architecture© (MSA)\u003c\/li\u003e\n\u003cli\u003eNegative Stiffness Mechanism Vibration Isolation (NSM)\u003c\/li\u003e\n\u003cli\u003eMechanical Crossover Technology (MCT)\u003c\/li\u003e\n\u003cli\u003eTri-Modal Platter system (TMP)\u003c\/li\u003e\n\u003cli\u003eEdge Damping Ring (EDR)\u003c\/li\u003e\n\u003cli\u003eTone arm Damping System (TDS)\u003c\/li\u003e\n\u003cli\u003eResonance Tuned Suspension (RTS)\u003c\/li\u003e\n\u003cli\u003eDiamond Like Coating Amorphous Material Bearing Friction Modifier (DLC)\u003c\/li\u003e\n\u003cli\u003eHigh Torque Adjustable Drive (HTAD)\u003c\/li\u003e\n\u003cli\u003eHigh frequency and RF absorption features\u003c\/li\u003e\n\u003cli\u003eRSA resonance control technology\u003c\/li\u003e\n\u003cli\u003eA suspension stabiliser for ease of operation during record changeover\u003c\/li\u003e\n\u003cli\u003eRecord Clamp with RSA resonance control technology\u003c\/li\u003e\n\u003cli\u003eLighting control system and power filtration functions\u003c\/li\u003e\n\u003cli\u003e0.5 Hz (Fz) Vertical\u003c\/li\u003e\n\u003cli\u003e1.5 Hz (Fz) Horizontal\u003c\/li\u003e\n\u003cli\u003ePush button Speed Adjust\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eWhat does a vacuum hold-down system do?\u003c\/b\u003e\u003cbr\u003eA 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 stabilizer rings). Aside from presenting a flat vinyl record, the vinyl and the platter present as one ‘effective mass’, which has sonic benefits.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eWhat are the sonic benefits of a well-designed vacuum hold-down system?\u003c\/b\u003e \u003cbr\u003e\u003cbr\u003e\u003cb\u003eEliminates warps and air gaps\u003c\/b\u003e\u003cbr\u003eA vacuum hold-down system forcibly flattens the record against the platter, whether the vinyl is slightly warped, has uneven pressing or simply isn’t perfectly flat. This ensures the stylus rides the grooves with consistent geometry. This can help avoid groove mis-tracking, distortion, or pitch instability that might otherwise result from warps or uneven contact. Because the entire surface is in intimate contact, you avoid “air pockets” under the record that might introduce resonance or micro-flutter. \u003cbr\u003e\u003cbr\u003e\u003cb\u003eBetter stylus tracking and groove contact\u003c\/b\u003e\u003cbr\u003eWith the record held perfectly flat and flush, the stylus can maintain consistent contact with the groove walls and floor, which improves tracking accuracy. This helps especially with delicate groove passages, subtle dynamics, and complex recording mixes, where even slight variations in contact can smear or blur detail. Also, because vacuum hold-down distributes force over the entire disc, it avoids some of the potential downsides of clamps (which only press at center) or weights (which increase inertia but may not flatten warped records completely). \u003cbr\u003e\u003cbr\u003e\u003cb\u003eReduces resonance, vibration \u0026amp; feedback loops\u003c\/b\u003e\u003cbr\u003eAnalog playback is highly sensitive: as the stylus tracks the groove, it generates tiny vibrations. Those vibrations can travel from the vinyl to the platter, bearing, and even into the tonearm or plinth — potentially feeding back into the stylus and muddying detail. By rigidly coupling the vinyl to the platter, the vacuum system reduces the chances for micro-movements and resonance, minimizing energy interplay between the stylus and platter. This means fewer distortions, less “smearing,” and a more stable, accurate reproduction of the groove’s fine details. \u003cbr\u003e\u003cbr\u003e\u003cb\u003eMore consistent speed \u0026amp; stability (less wow\/flutter noise)\u003c\/b\u003e\u003cbr\u003eOnce the record is tightly coupled to the platter, there’s less likelihood of slippage or micro-variations in rotation, both of which can cause wow and flutter (subtle pitch fluctuations) or timing instability. A vacuum system results in a minimal increase in rotational inertia compared to heavy weights, meaning less strain on the motor and platter bearing, yet you gain improved rotational stability. \u003cbr\u003e\u003cbr\u003e\u003cb\u003eIncrease in sonic clarity, detail and accuracy\u003c\/b\u003e\u003cbr\u003eThe overall improvement of superior stylus contact, reduced micro-vibrations and the elimination of warps\/air gaps is less resonance and fewer mechanical anomalies. This allows the stylus to convert the groove geometry into an electrical signal more accurately. Discerning listeners report fewer distortions or coloration, which often improves mid-range purity and clarity of vocals and instruments. Tighter bass, greater low frequency clarity, improved transient impact (drums, percussion), more image stability and better overall fidelity. \u003cbr\u003e\u003cbr\u003e\u003cb\u003eA two chassis system\u003c\/b\u003e\u003cbr\u003eThe Helix One Mk3 Vacuum turntable system consists of the main turntable chassis that sits on its powerbase and a second vacuum system chassis (box).
