Pro-Ject Speed Box S Black - Electronic engine control with speed selection

Useful accessory for Pro-Ject turntables that do not have a built-in electronic speed switch. The Speed Box S allows for switching between 33 and 45 revolutions per minute at the push of a button. The filtered and quartz-stabilized control ensures absolute running smoothness with minimal speed deviation. The Speed Box S is compatible with many Pro-Ject turntables, and with some models, it is also possible to play shellac records (78 revolutions per minute) using the optional Pulley SB.
