Using the same DSP (digital signal processing) generator found in the RP10 the Neo is built upon a high stability crystal. The Neo features an advanced anti-vibration circuit fine motor speed adjustment and the convenience of electronic speed change. The DSP generator will divide the accurate signal from the crystal to the exact frequency required to turn the platter at the selected speed whilst will producing a near perfect sinusoidal waveform to drive the 24v motor.
