Inner groove distortion is a phenomenon that occurs when centripetal forces during platter rotation pull the tonearm towards the center of the record, leading to an imbalanced stylus pressure on the groove wall and resulting in distorted sound. To counteract this, tonearm designs require a bias adjustment mechanism, which increases the force gradually as the tonearm approaches the center, compensating for the varying centripetal force.
Our tonearm design incorporates a mechanism that gradually increases force to counteract the centripetal effect as the tonearm approaches the center of the record, providing a unique solution to the issue of inner groove distortion. This results in consistent musical enjoyment from start to finish, differentiating us from other tonearm designs that may not address this problem as effectively.
