Premium balanced sound upgrade

Use the single-ended RCA, or go balanced with the 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 to either 24dB or 30dB.

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.

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