MODEL-30/2 (without arm)
With its many original design features the Model 30/2 is a unique turntable. There are no critical adjustments or setting up procedures. Its immaculate construction and finish stem from facilities and uncompromising quality control which have made SME a byword for engineering excellence. The sub-chassis is machined from 19mm thick aluminium alloy plate and weighs approximately 17kg while the base with its four supporting pillars adds a further 16kg. This offers the high mass and stiffness required for uncoloured reproduction further aided by efficient extensional damping of both components to reduce the amplitude and duration of their vibrational modes.
Built-in locks one at each corner of the sub-chassis, enable the suspension to be secured and automatically sealed for transport. Model 30/2 is equipped for but not including SME precision pick-up arm.
The turntable is driven by a 3-phase, 6 pulse, inductance motor, with 8 pole Neodymium magnets and 3 integrated Hall position sensors.
The electronic controller uses a high performance microcomputer, optimised for motor control allowing very and accurate and stable speed control, including 33.3, 45 and 78 rpm.
This design incorporates a 4 layer surface mount technology pcb with on-board user adjustable speed variation control.
