The S2 Speed Box from Pro-Ject offers a functional and convenient upgrade for many Pro-Ject turntables with a 16V AC motor that do not already have built-in speed control. It  acts as an AC generator for the turntable, replacing the fluctuant supply from a normal 16V power supply and regulating it. The result is a clean power signal that allows the motor to perform optimally. The added convenience is that the S2 Speed Box can shift frequency, for easy changing between 33 and 45RPM at the push of a button.

Inside, the S2 Speed Box makes use of high-quality materials in the quartz-controlled oscillator and filter circuits. Externally it is stylish, compact and minimal, matching any other S2 Box Design component. 

Connection is simple, as the S2 Speed Box is supplied with a link cable that plugs into your turntable instead of the normal power supply. There is also a wide range of compatibility and in some cases it can even add 78RPM compatibility, when partnered with a special Speed Box Pulley.

Please note: The S2 Speed Box will not work with newer Pro-Ject turntables that feature a DC power supply. It will only work with older AC powered turntables that feature an external 16V power supply and do not already have built-in speed control.
