SME are proud to enter our 75th anniversary year in 2021 as the world’s finest turntable and tonearm manufacturer. 75 years on we continue to deliver on our status as a highly respected and iconic British brand, founded by audio legend Alastair Robertson-Aikman in 1946.
The MK2 Model 12 is a precision turntable of high mass made to exacting engineering standards for high performance. The chassis and sub-chassis are CNC machined from premium grade aluminium billet. The sub-chassis is suspended on an advanced isolation system for primary resonance control and houses the main bearing, platter and tonearm. Four fully adjustable feet are mechanically de-coupled from the main chassis by isolators providing base resonance control.
The main spindle is 19mm precision machined from high chrome tool steel, ground, super finished and supported in a sealed housing with individually fitted sintered bronze bearings of generous proportions needed for precise bearing and platter rotation.
The platter is machined from aluminium alloy and weighs over 4.6kg. Extensionally dampened with the top surface iso-damp, diamond-turned with a fine scroll for acoustic performance. This method of finishing upsets a myriad of tiny fibres which interface with the underside of the vinyl record. A substantial record clamp operating on the reflex principle ensures the largest possible platter contact even when appreciable record warp is present.
The motor conforms to the highest standards of silent running and the turntable is driven by a custom made bi-phase AC synchronous motor controlled by a highly advanced speed control unit providing precise speed accuracy and stability.
Speed Control Unit
The Speed Control Unit uses a dedicated DSP engine to generate two independent pure mathematical sine waves which provide total control of frequency, phase relationship and amplitude. These in turn are matched (tuned) to the motor for accuracy to obtain the best possible performance.
The speed range is 33.33 and 45rpm with independent memory settings via a switched encoder. Fine pitch speed increments/decrements of +/-0.01% of the selected speed are made by a rotary control on the Speed Control Unit fascia. The SCU case is CNC machined from billet aluminium. A separate mains Power Unit keeps the transformer away from the SCU and importantly separated from the turntable audio signal cables.
Crystal Cable Wiring
The Model 12 is equipped with a premium grade signal cable from Crystal Cable which is installed inside the tonearm. Pure mono-crystal silver conductors in miniature format. Providing precious metal in its most pure version, lifting the musical performance to a higher level.
