Replacing the celebrated Speed Box S, the Speed Box S2 is a high-precision external electronic speed control designed expressly for Pro-Ject turntables. With ultra-compact dimensions and presented in a chassis of entirely metal construction, the Speed Box S2 is a product whose primary function is to allow the adjustment of the rotation speed of the traction motor and, therefore, go from 33 rpm to 45 rpm without need to manually change the drive belt from one pulley to another. But the Pro-Ject also performs another function: since it incorporates a quartz oscillator and a microprocessor, it ensures extraordinary stability to the motor rotation. Specifically, its precision of 0.001% makes it possible for rotation stability to be multiplied by five. Likewise, lovers of vintage records will be pleased to know that it is also possible to obtain 78 rpm rotation by adapting a specific pulley and selecting 45 rpm. The Speed Box S2 is powered by an external, direct current, low noise power supply that contributes to reinforcing its exceptional performance.
