Description
Moerch model UP-4 is a tonearm for your turntable that is built around Moerch’s unique uni-pivot design. The UP-4 offers great accuracy and stability when following the grooves on your turntable.
UP-4 Design
Moerch’s model UP-4 tonearm has a unique uni-pivot design. The bearing, which is dampened in all directions, is made of a hardened steel pivot resting on a concave, polished sapphire. The low positioning of the bearing provides better stability because a considerable part of the moveable mass of the arm is placed above the pivot point.
Customisable Tonearm
The model UP-4 uses counterweights for the azimuth adjustment to allow you to get the best level for tracking. Like all Moerch models, they also have the facility of interchangeable arm wands.
