SME Model 60 Turntable with Series VA Tonearm

Design features include: de-coupled adjustable feet with multipoint isolation, an intelligent suspended suspension system with horizontal and vertical control, hydraulically dampened main bearing, acoustically treated main chassis, sub-chassis and platter, sophisticated new generation drive system with highly accurate speed control, AC motor and independent power transformer. 

The Model 60 is equipped with the new Series VA tonearm which is an advanced version of the famous Series V tonearm which has been extensively sonically improved by use of a non-metallic tonearm CNC machined from an advanced polymer resin material with high density and high rigidity properties. The Series VA tonearm tube is acoustically inert with a significantly reduced resonance signature, optimised effective mass and a wide cartridge balance weight range

The turntable is driven by a custom made bi-phase AC synchronous motor. 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 output driver stage is a 2 channel, class AB Bi-polar design with low distortion and relay coupled directly to the motor. The entire design is implemented using high quality surface mount technology on a gold plated FR4 PCB.

The speed range is 33.33 and 45rpm with independent memory settings via a switched encoder.
