RS Laboratory RS-A1


The RS-A1 tonearm is based on the theory that the tonearm should be the mechanical earth to the vibration system.

Much like an electrical system where the ground potential is the potential where all other references are considered.

To pick up the tone signal accurately from the disc, the support part of vibration system (including cartridge body, shell, arm, arm base) should not be moved relatively to the vibration system.
