Created as a companion and to compliment the Series V-12, the Model 30/12 precision turntable enjoys all of the features associated the Model 30/2 precision turntable. The differences are merely ones of scale. The suspension now provides 60 purpose moulded ‘O’ rings supporting the sub-chassis, which has been increased in thickness by some 16%, on one hundred and twenty strands of rubber. The main chassis has received similar attention but in this case the thickness has been increased by 19%. Small differences but necessary to afford the increased rigidity required to ensure acoustic neutrality.
A larger version of our well known Model 30/2, it will accept nine, ten and twelve inch arms but is especially directed at the exciting Series V-12. This offers performance 27% better than a nine inch arm in respect of angular error distortion. Its immaculate construction and finish stem from facilities and uncompromising quality control which have made the name SME a byword for engineering excellence.
CHROME FINISH OPTION
A special chrome finish option is available for the Model 30.
GOLD FINISH OPTION
A special gold finish option is available for the Model 30.
9, 10 and 12 inch arms, but designed to compliment our very own Series V-12 tonearm.
No sonic footprint, the sub-chassis is hung on one hundred and twenty strands of rubber in the form of sixty purpose moulded ‘O’ rings. An ingenious method of anchorage allows them to be removed or replaced instantly.
Sub-chassis motion is disciplined by four fluid dampers, one in each of the supporting columns. These eliminate overshoot and give almost zero Q recovery. The isolation needed to prevent acoustic feedback is bridged by the resistive coupling of the damping fluid through which unwanted reacted energy is conducted away to ‘ground’. This function is adjustable through trimmers which can be used in conjunction with a gauge to give recommended settings or varied to suit individual conditions.
330 mm (13”) diameter weighing 7.5 kg (17 lbs). The face is machined with a fine scroll found to interface better than a plain surface. A substantial reflex clamp ensures maximum contact with the platter even when severe record warp is present. The sub-chassis/arm mounting board interface is extensionally damped and the mounting board is reversible to allow mounting of nine inch pick-up arms when necessary.
The turntable is driven by a 3 phase, brushless outrunner motor with 8-pole Neodymium magnets and 3 integrated Hall effect sensors and virtually vibrationless by reason of its 2.5 kg (5.5 lbs) weight as well as being isolated on urethane mounts that are adjustable for accurate belt positioning.
The electronic controller uses a high performance microprocessor, optimised for motor control. Closed loop speed control is implemented using a proportional plus integral (PI) algorithm. Fine pitch speed adjustment allows increments/decrements of +/-0.01% of selected speed. Speed ranges: 33.3, 45 & 78 rpm.

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. The Hall position sensors on the motor provide accurate feedback to the micro controller allowing very accurate and stable speed control, including 33 1/3, 45 and 78 rpm. The reference oscillator is a 10MHz quartz crystal, which is multiplied by 4 to produce an internal microprocessor clock speed of 40MHz.
The driver stage has CMOS buffers/MOSFET drivers with 1.2 Amp peak drive capability.
The power output stage is six high power complimentary Mosfets in a 3 Phase Bridge Driver configuration.
Closed loop speed control is implemented using a pseudo sine wave commutation sequence and a proportional-plus-integral (PI) algorithm.
The design incorporates a 4 layer surface mount technology pcb with on-board user adjustable speed variation control.
