- Effective length: 233.15 mm
- Overhang: 17.8 mm
- Effective mass: 10.0 g / 11.0 g
- Weight: 700 g
- Unique one-piece pressure die-cast tone-arm utilising the
advantages of magnesium, replaces 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.
- Stainless steel cross shaft, ground and thread ground. Carried
in massive yoke on 10mm ABEC 3 ball races. Axis at record mean level to minimise
warp-wow.
- 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
filarnent. 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. Adjustment leadscrew journalled in
twin ball races with lever clamping.
- Swivelling damped output socket minimises vibration transmission
in sub-chassis use.
- Reference lines on tone-arm facilitate VTA setting.
- Fine adjustment of horizontal tracking angle (HTA)
- New design alignment protractor sets HTA with great accuracy.

The Series IV precision pick-up arm owes much to the technology developed for
the acclaimed Series V. Although presented at a lower price it retains the
unique one-piece magnesium tone-arm, dual-lock base and other advanced features
listed.
The Series IV is a worthy relative of 'the best pick-up arm in the world' with a
sonic performance reflecting the care and attention to detail underlying its
design and manufacture. |
