SME SERIES 312S

ADDITIONAL INFORMATION

BUILD

The 12in pressure die-cast magnesium construction takes advantage of the reduction in maximum tracking error/distortion afforded by the greater arm length when compared with 9in models.

• Unique pressure die-cast magnesium shell detachable and interchangeable without disturbing cartridge or wiring.
• Design of headshell clamping ensures a rigid junction with the tone-arm.
• Stainless steel cross shaft, ground and thread ground. Carried in massive yoke on 10mm precision ball races. Axes at record mean level to minimise warp-wow.
• Unique assembly gives high rigidity and allows bearings to be critically adjusted before the tone-arm is fitted.
• Stainless steel vertical shaft, ground and thread ground, with integral 16mm diameter flange to couple shaft and yoke.
• 23mm diameter steel pillar, heat treated, ground and honed, carries two 17mm precision ball races, widely spaced to resist tilt.

DAMPING

• Internal constrained layer damps minute residual vibrations making tone-arm acoustically inert.
• Tungsten-alloy balance weight carried on two-point suspension. Extra-low inertia design assists warp riding.
• Underslung weight housing corrects centre of gravity and provides non-reflective tone-arm termination.
• Swivelling, damped output socket minimises vibration transmission in sub-chassis use.

ADJUSTMENTS

• Anti-skate control operates through tension spring and filament. Dial calibrated to correspond with VTF and has positive OFF position.
• Lowering/raising control gives smooth positive action. Height of lift can be adjusted.
• Dual-lock base provides movement control with high rigidity.
• Reference lines on tone-arm facilitate VTA setting.
• Fine adjustment of horizontal tracking angle (HTA).
• Cartridge leads and internal wiring in Silver litz.
