The linear tracking arm of the PS-LX500 is designed to duplicate the movement of the head which cuts the record master. Compared with a pivoted arm, a linear tracking arm has a very small tracking error (with greatly reduced harmonic distortion) and almost no pressure on the inside wall of the groove, which means improved tracking ability and channel separation. The arm transport buttons allow you to move the tonearm easily over the desired point of the record with the dust cover closed. Start/stop of the record play and tonearm up/down can also be controlled using the buttons on the front panel. Using the optional RM-44 remote controller, start/stop play and tonearm up/down can be remotely controlled.
