  • Improved power supply for older turntables
  • Automatic switching between 33 and 45RPM
  • Makes some turntables 78RPM compatible

The Speed Box S2 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.

The Speed Box S2 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 Speed Box S2 can shift frequency, for easy changing between 33 and 45RPM at the push of a button.

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

Connection is simple, as the Speed Box S2 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 (see below), and in some cases the Speed Box S can even add 78RPM compatibility, when partnered with a special Speed Box Pulley.

Please Note: The Speed Box S2 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.
