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 (see list on homepage) and some also offer the possibility to play
78 rpm records with the addition of a special accessory pulley!

YES, BUT your turntable motor needs to be less than 3Watts power, it must be a 16V AC motor (non-DC motor, non-DC power supply) and there must be no phono preamplifier integrated. If you have an electronic speed regulation built into your turntable, also please do not use this speed box!
