Overview
SDS Drive
The Synchronous Drive System (SDS) combines a turntable motor speed controller and a line isolator into one convenient 407(W) x 77(H) x 305(D)mm package. The SDS breaks new ground in clean accurate power delivery using advanced digital technology and quartz crystal accuracy.The SDS allows for the adjustment of both the voltage and frequency fed to the turntable motor. Adjustments are easily made from the front panel using intuitive, soft touch controls. The selected output voltage and frequency are shown using large, easy to read LED displays. The SDS slowly ramps the voltage and frequency up or down to the selected value in order to prevent premature motor wear due to abrupt changes. During motor startup, the SDS increases its output voltage in order to bring the platter up to speed quickly. Once the desired platter speed has been reached, the SDS ramps the output voltage down in order to reduce motor vibration and, therefore, the systems noise floor.
The circuit used in the SDS provides an incredibly accurate line frequency of great stability. Additionally, the electronic circuitry effectively isolates the output voltage from the input voltage, doing away with voltage spikes, low level fluctuations, RFI, and frequency variations.
Instead of merely filtering the power line, the SDS first changes it into pure DC voltage and then digitally regenerates its own clean signal. This approach is superior to that used in many of the other power line conditioners on the market.
