The Reed 5T Tonearm pivoted tonearm has a unique design that uses a servo-controlled, battery-powered motor and a laser to enable it to track tangentially and also to address antiskating. Compared to pivoted tonearms, the 5T's smaller moment of inertia allows for better tracking.
Arm tube suspension system is similar to one used in Reed 2G tonearm, and the tonearm’s turning part is based on low noise thrust-sleeve bearing. For angular rotation of tonearm we designed and built limited rotation sectional torque motor. Tonearm’s position is controlled by laser and linear sensor array.
The 5T has user-replaceable arm tube – feature, which allows to change tonearm’s effective mass yourself. Tonearm also has VTA and azimuth adjustments.
Reed 5T has following advantages if compared with pivot tonearms:
Smaller moment of inertia,
No need for anti-skating mechanism,
Max tracking error is +/- 5 Minute of Angle (MOA). (Figure 2). Pivot tonearms usually have max tracking errors up to 1.5 deg.
