The Speed Box DS provides the best possible performance with convenient & accurate speed change at the touch of a button!
A very useful accessory for many Pro-Ject turntables, that do not offer a built-in electronic speed change. The Speed Box DS performs this change by the push of a button between 33 and 45 rpm! The quartz regulation and filter circuit gives a far better speed stability for smooth and undisturbed motor operation. Speed Box DS is compatible with a lot of Pro-Ject turntables!
