The Synchronous Drive System (SDS) combines a turntable motor speed controller and a line isolator into one convenient 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 the frequency fed to the turntable motor. 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.

The SDS works best with synchronous motor driven turntables, such as those from VPI. The speed of a synchronous motor is determined by the frequency it is fed. It is only logical then that a device with which speed is based on the line frequency will always function better when a stable frequency is delivered. A constant motor speed translates into a quieter, more faithful musical presentation.

Synchronous turntable motors benefit from the SDS. My VPI HW-19 Mk-III motor works more silently, and smoother. It's rotational speed can be set precisely or to chosen variations. The motor coasts with reduced stress (and notable smoothness) when the SDS reduces the working voltage upon reaching the chosen speed. My synchronous 'table is more silent, accurate, consistent and smoother with the SDS. It has worked perfectly for 15 years without missing a single day!
