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!
** Use only with 230 & 16 volt power connection, that use AC motors
Does not work with DC power supplied turntables
