Pro-Ject MC Step Up Box DS3 B Step Up Transformer

The MC Step Up Box DS3 B is a premium step-up transformer for moving coil cartridges, particularly suited to balanced turntable connections.

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 DS3 B makes use of high-quality Lundahl LL1678 audio transformers to ensure every piece of musical detail is passed through to the phono stage. For further system compatibility it is also possible to select between RCA and XLR inputs and outputs as well as choosing between two transformer ratios depending on the level of gain required.

The MC Step Up Box DS3 B delivers remarkable clarity with minimal noise and distortion. Suited to both balanced and unbalanced systems, it is one of the most flexible step-up transformers available today. 

The new MC 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.
