-Sme Series V Tonearm
SME engineers, recognising the potential of the latest complementary equipment, accepted the challenge to design and build a pick-up arm which unlike others in existence would make no detectable sound contribution of its own. The work took almost four years and the measure of its success is the acceptance of the SME Series V precision pick-up arm by technical experts and users as one of the world's truly great audio products. The SME Series V Tone Arm sound has an almost startling dynamic range and neutrality enabling high levels to be enjoyed. It escapes the 'LP' sound and demonstrates that structural resonances in pick-up arms are responsible for much that makes vinyl records readily discernible from master tapes.
The SME Series V Tone Arm excellent vibration analysis results owe much to the high stiffness and damping of its tone-arm, but stiffness to be of value must refer to something rigid. Tests disclosed the many points at which rigidity could be lost so all other principal parts were pressure die-cast allowing each to be tailored precisely for its purpose and utilising the high mass of zinc-based alloy to damp out vibration. Ultra-high quality 10mm and 17mm ABEC 7 radial shielded bearings were selected to provide low friction vertical and lateral movements, while holding the tone-arm motionless against front/back and torsional forces. The support afforded by these large, wide contact angle bearings, excludes the possibility of chatter and wear or damage in normal use.
Electrical aspects received no less attention. The internal wiring is of specially developed silver litz, each conductor having five insulated strands. The damped output-socket swivels allowing it to take up its own position for installation and to minimise vibration transmission when used on a sub-chassis. The high quality linear crystal oxygen-free copper audio lead selected for its electrical and mechanical characteristics is terminated at one end with SME right-angle 5-pole DIN contra-plug and gold-plated phono plugs at the other.
The magnesium tone-arm is finished in satin black enamel, other major parts in black chrome with details in bright chrome and polished stainless steel. Each unit is complete with tools, accessories, and an advanced drill jig/template and alignment system simplifying mounting and exact placing.
Structurally inert the SME Series V Tone Arm embodies every worthwhile feature in a pick-up arm. As part of a complete system working in concert with a comparable turntable and cartridge it will provide wide range transparent reproduction of vinyl L.P's, bringing the listener audibly closer to the clarity and dynamics of the original performance.
Unique one-piece pressure die-cast tone-arm utilising the advantages of magnesium, replace conventional fabricated construction. Internal constrained layer damps minute residual vibration leaving the tone-arm acoustically inert. Fine machined cartridge platform, enamel free to avoid interface resonance. A Stainless steel cross shaft, ground and thread ground. Carried in massive yoke on 10mm ABEC 7 ball races. Axis at record mean level to minimise warp-wow. Dynamic balance graduated vertical tracking force (VTF) control applies 0-3g x 0.125g through resonance controlled spring. Unique assembly gives high rigidity and allows bearings to be critically adjusted before 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 ABEC 7 ball races, widely spaced to resist tilt. 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. Subsonic lateral mode fluid damper can be instantly adjusted or cancelled. 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. Adjustment leadscrew journalled in twin ball races with lever clamping. Swivelling damped output socket minimises vibration transmission in sub-chassis use. Fine adjustment of arm height (VTA). Reference lines on tone-arm facilitate VTA setting. Fine adjustment of horizontal tracking angle (HTA). New design alignment protractor sets HTA with greater accuracy. Advanced jig/template system guarantees correct positioning.
