A better foundation for stable rotation

Steady platter rotation is fundamental to vinyl playback. Even minuscule and momentary speed variations can degrade the soundstage and obscure the musical timbre. Pure Fidelity turntables reflect a comprehensive approach to rotational stability, upgraded with the quartz-locked Conductor speed control now included with our turntables.

Quartz crystal precision of ±0.003%. The combination of a quartz crystal reference frequency and microprocessor phase-locked-loop control maintains speed within ±0.003%. Even temperature changes in your listening environment will not affect platter speed.

High precision pitch adjustment.

Because many classic albums pre-date modern speed control, they may have been mastered at speeds slightly higher or lower than 33-1/3 rpm – rendering music slightly sharper or flatter than perfect pitch. The Conductor speed control enables you to compensate for off-speed discs across a range of ±5% in 0.2% steps. Rear panel controls provide separate pitch adjustment for 33-1/3 and 45 rpm discs, with a center detent for easy return to factory calibration.

Factory calibration. To assure ultimate rotational accuracy at the pitch adjustment center detent, we calibrate each Conductor SC to each individual turntable.

Achieving clean power.

As the name implies, AC synchronous motors are controlled by the alternating current they are fed. While your household AC mains might be fine for lightbulbs and dishwashers, it’s beset by noise, spikes and distortions – poorly suited to turntable drives. Dirty power degrades motor performance and impairs your listening experience. For this reason, the motor drive voltage is completely isolated from your household mains.
