Upgrade to best possible turntable performance with convenient speed changeover through keypress!
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 and some also offer the possibility to play 78 rpm records with the addition of a special accessory pulley!
