The Quartz-controlled oscillator of the Speed Box SE II generates clean AC-power without mains distortion. Power outputs are galvanic decoupled from the input current. Many turntables in the market (including all the Pro-ject models) use AC synchronous motors and the Speed Box SE II can be used for ultimate speed consistency and electronic speed change between 33 and 45rpm. Additionally, speed can be altered in graduated steps on either setting.
