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

Pro-Ject Speed Box S Electronic Speed Changer

 

Inside, the Speed Box S 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 S Line component. 

Connection is simple, as the Speed Box S 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.

Key Features:

  • Electronic speed change between 33 and 45RPM (see below)
  • 78RPM also possible after fitting accessory pulley (see below)
