- A very useful accessory for many Pro-Ject pickup plates that do not offer the possibility to change the rotation speed. The Speed Box S2 performs this change at the push of a button between 33 and 45 rpm!
- The quartz filter and regulation circuit provides much better speed stability for smooth and undisturbed engine operation.
- The Speed Box S is compatible with lots of Pro-Ject pickups (see list below) and others offer the ability to play 78rpm recordings with the addition of a special accessory wheel!
- Compatible with the following products:
- 33/45 and optional 78 with additional accessories: Pro-Ject Debut III, Debut Carbon (US version with 16 volt motor), 1-Anniversary, Art-1, 1-Xpression III & Classic, RPM-5.1
- Do not use with the following products:
