Suspended on thirty purpose moulded 'O' rings, the SME model 15 sub-chassis and platter weighs more than 11Kg making it a high density construction on which freedom from colouration depends.
The suspension is adjustable through trimming screws in each column and when used with a gauge, it can give recommended settings or varied to suit individual requirements.
The central fluid damper disciplines the suspension while manipulating the sub-chassis motion to provide a resistive ground for acoustic signals, eliminating overshooting and giving almost zero 'Q' recovery.
Machined from aluminium alloy, the platter weighs over 4.6kg and is extensionally damped. The diamond-turned upper surface features a fine scroll and the finishing method disrupts a myriad of tiny fibres which interact with the underside of the record.
A significant clamp operating on the reflex principle increases platter contact to the largest possible and a considerable record warp is applied. The central spindle is 19mm and constructed from high chrome steel, ground super finished and supported in a sealed housing with separately fitted sintered bronze bearings that are needed to support the platter.
The Model 15 motor is built to the higest standards of silent running in a turntable. Driven by a 3-phase, brushless outrunner inductance motor with 8-pole Neodymium magnets and 3 integrated Hall position sensors, the electronic motor controller uses a high performance microporocessor that is optimised for motor control.
Closed loop speed control is implemented using a proportional plus algorithm while fine pitch speed adjustment allows you to tweak the selected speed at increments/decrements of +/- 0.01%. The speed ranges can be chosen from between 33.3, 45 & 78 RPM.
A soft dust cover is provided to accomodate the turntable and arm, when not in use. Mains voltages available are 90-110V, 105-125V and 220-240V 50/60Hz. Standard arm mountings suit all SME 9" and 10" arms.
The SME Model 15 turntable is available with or without the 309 tonearm.
