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.
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.
- Electronic speed change between 33 and 45RPM (see below)
- 78RPM also possible after fitting accessory pulley (see below)
- Replaces the existing 16V turntable power supply
- Quartz-generated high precision electronic speed regulation
- Creates a cleaner AC mains signal for your turntable
- Allows the motor to run more efficiently and with less resonance
