ADC Series IV

Stereo Phonographic Cartridge

ADC Series IV


The Series IV cartridge has a new, high compliance pivot-armature system. Critical tolerances are held to within 1/4 the thickness of a human hair to assure precision assembly and consistency from one stylus to another.

The Omni-Pivot system is assembled without the use of unpredictable adhesives, wires or restrictive armature governors. Each armature is micro-machined to perfectly lock into ADC's newly formulated, high-definition suspension block, which provides optimum location of the armature, at all times.
