Dear Clearaudio customer,

Congratulations!
Thank you for choosing the “Accu Drive” a revolutionary turntable DC power supply, a high
quality product made in Germany by Clearaudio.

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” Accu Drive”:
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” Accu Drive‘s” constant charging system maintains the accumulatores 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.

We wish you a lot of pleasure with your new Clearaudio “Accu Drive” power supply.

After 30 seconds the device goes into the charging mode.
Depending on the existing residual charge of the integrated accumulators the charging time
may vary.
If the nominal charge is reached the load deactivation happens automatically.

Only after this first charge, you should connect the device to the appropriate
consumer load.
