Pro-Ject MC Step Up Box DS3 B

The MC Step Up Box DS3 B 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 DS3 B 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.

Lundahl LL 1678 - Balanced In/Out

For the MC Step Up Box DS3 B we use high quality Lundahl LL 1678 audio transformers to ensure every detail remains. You can set the transformer ratio with a push of a button on the back panel.

Use the single-ended RCA, or go balanced with the miniXLR or XLR in- and outputs and benefit from a low noise interference free signal transmission. Switch the in- and outputs via the push buttons on the front. Additionally, you can set the gain level either on 24dB or 30dB.

Designed & handmade in Europe

The new Step Up Box DS3 B 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 DS3 B 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.
