PRO-JECT MC Step Up Box S3 Step Up Transformer

Sound upgrade for your MC cartridge

The output level of MC cartridges is very low, compared to a MM (Moving Magnet) one it is about 10x lower, which means, you need a special phono amplifier. A higher gain is needed to utilize the signals, which can result in a higher noise level and distortion. The MC Step Up Box S3 is the solution.

We always recommend a step-up transformer in combination with a high quality MM phono (especially tube) preamp, rather than MC phono preamplifiers.

Lively, dynamic & natural

The MC Step Up Box S3 works very differently compared to a phono preamplifier. The windings ratio of the transformer determines the gain factor. As it works completely passive and no external power is needed, no extra power can be produced. The increase in voltage is achieved by a coresponding decrease is current. As there is no amplification, the MC Step Up Box S3 has a remarkable noise performance and a very low level of distortion. The sound with a Step-Up Transformer will be more lively, dynamic and natural.
