Pro-Ject MC Step Up Box S3 Step Up Tranformer

The Step-Up Box S3 is an affordable Step-up transformer that operates within your system passively, and provides your Moving Coil with a sound upgrade, and boosts the output signal in order to increase the overall efficiency of your system.

The MC Step Up Box S3 is a high-quality step-up transformer for moving coil cartridges, bringing new levels of flexibility and convenience to premium analogue systems.

Step-up transformers exist to passively increase the output level of a moving coil pick-up cartridge to a level like that of a typical moving magnet design. The level of gain achieved is defined by the winding ratio of the transformer. By making this initial gain phase entirely passive no extra power is required, and the audio signal can maintain its integrity. The further benefit is that less electrical power is now required from the phono stage, further allowing the signal to be freer of unwanted electrical noise. 

The MC Step Up Box S3 makes use of premium materials throughout to deliver a high-quality sound performance. The 1:16 transformer ratio is suited to a wide range of modern pick-ups, allowing the transformer to function as a great upgrade solution for high-end integrated amplifiers that are limited by a built-in moving magnet phono stage. 

The new Step Up Box S3 is carefully designed and handmade in Europe. Our goal is to develop a technically flawless device in a housing that is only as big as necessary to safe raw materials. Due to the timeless design & rigid aluminium casework, the MC Step Up Box S3 is built for eternity.

With high-quality materials and components, but also well-thought-out design, we want to be a pioneer in the industry.
