The high performers in the Clearaudio turntable range – the Innovation series, Ovation and Performance DC - all use sophisticated decoupled high-torque DC motors. Even in the top models which employ technological advantages such as Clearaudio's optical speed control (OSC), the drive system is vulnerable to degradation from a polluted mains power supply.

Enter the accudrive: a revolutionary turntable DC power supply. It pairs twin lead acid batteries with a complex electronic security mechanism to protect against short circuit, overload, noise and voltage fluctuations. The accudrive's constant charging system maintains the batteries in optimum operating condition and feeds the turntable drive system with the perfect 24-volt with less than 0.2 mV deviation. The result is pitch stability and a purity of sound beyond expectation.
