VPI ADS
Best speed controller for audiophiles seeking perfect turntable pitch stability.
The VPI ADS Analog Drive System is a precision speed controller designed to provide exceptionally accurate speed stability for compatible turntables. It features two pure analog frequency generators with low distortion and noise, coupled with a high-current Class-A/B amplifier. The system offers analog control logic for quiet operation and precise 33/45 RPM speed adjustment. It is easy to set up, requiring only a connection to compatible turntables with AC synchronous motors under 10 watts. The ADS is designed to be left powered on for optimal performance and features illuminated indicators for status and speed selection.

Know before you buy
The ADS is compatible with most turntables that utilize an AC synchronous motor rated under 10 watts. It works with both belt-drive and direct-drive systems, provided they meet these power requirements.
No, the unit is designed to remain powered on at all times. Leaving it on ensures the internal components stay at an optimal operating temperature for the best sonic performance.
By using pure analog frequency generators and a high-current Class-A/B amplifier, the ADS provides a cleaner, more stable power signal to your motor. This reduces speed fluctuations and electrical noise, resulting in tighter pitch stability and a lower noise floor.
Yes, the ADS features precise analog speed adjustment for both 33 and 45 RPM settings. It comes factory-calibrated, but allows for fine-tuning to ensure your playback speed is perfectly accurate.
Setup is straightforward. You simply connect your turntable's AC power cord directly into the ADS output and plug the ADS into your wall outlet, requiring no complex wiring or modifications to your turntable.
