About the Speed Box S
The Speed Box S is an accessory for Pro-Ject turntables that lack built-in electronic speed change. It provides a convenient way to switch between 33 and 45 rpm with the press of a button. The quartz regulation ensures high precision speed stability of +/- 0.001%, contributing to smoother motor operation and reduced mains interference. The device is compatible with turntables using a 16-volt AC motor and is available in black or silver finishes.
