The Series 300 broadens the application of SME technology.
Although the unique one-piece magnesium tone-arm is used for the Series 300 Model 309, advanced metal techniques produce a fabricated arm of exceptional stiffness for the Series 300 Model 310 and 312 arms thus allowing a choice of three arm lengths to suit all decks.
The detachable magnesium headshell has a new style coupling, providing the convenience of rapid cartridge interchange without loss of rigidity.
SME designers can be proud of these models which offer a performance and manufacturing excellence unmatched by many more expensive models.
- Unique pressure die-cast magnesium shell detachable and interchangeable without disturbing cartridge or wiring.- New design clamping arrangement ensures rigid junction with tone-arm. - Internal constrained layer damps minute residual vibrations making tone-arm acoustically inert.- Unique assembly gives high rigidity and allows bearings to be critically adjusted before tone-arm is fitted.- Anti-skate control operates through tension spring and filament. Dial corresponds 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.- Tungsten-alloy balance weight carried on damped 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.- Reference lines on tone-arm facilitate VTA setting.- New design alignment protractor sets HTA with great accuracy.
