Low output MC moving coil phono cartridges send an output that’s about a tenth the output of MM moving magnet phono cartridges. This means they require a specialty phono preamp with more gain and different electrical parameters – unless you add a step-up transformer to prep the signal for your MM phono stage. The Pro-Ject MC Step-Up Box DS3 B works very differently from a phono preamplifier. The windings ratio of the transformer determines the gain factor. Because it’s a passive device that doesn’t require a power supply, no additional power can be produced. The increase in voltage is achieved by a corresponding decrease in current. Since there is no amplification, the MC Step-Up Box DS3 B is remarkably low in noise and distortion with a lively, dynamic and natural sonic signature.
