Utilise the single-ended RCA or opt for balanced signal transmission with the XLR inputs and outputs, which offer the advantage of low noise and interference-free transmission. 

The MC Step Up Box S3 operates distinctly from a phono preamplifier, with its gain factor determined by the transformer's windings ratio. Functioning entirely passively, it requires no external power. Voltage increase is accomplished through a corresponding decrease in current.

With the new Power Box RS2 Phono you can connect both your turntable and phono preamp, and benefit from the perfect power contribution. The new Power Box is compatible with all of our Phono Boxes and every 15V DC Pro-Ject turntable.
