The RONDINE 3 provides 33, 45, and 78 rpm and nine other fixed speeds for vintage discs and half-speed mastering. Its small DC belt-drive motor and Lo-Noise power supply results in very low rumble and ultra-low hum. Arm height is adjustable for all discs. The spindle is removable for correcting eccentric records. The Delrin platter is similar in composition to the actual discs played and provides them with excellent dampening, resulting in neutral sound.
