Premium step-up transformer

Made In Europe


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 either on 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.

Balanced XLR

Interference free

A balanced connection can extract the final musical information, effectively filtering out any noise from interferences stemming from our noisy, modern homes.

Lundahl LL 1678

High quality transformers

Lundahl transformers ensure highest sound quality and that every detail of your record remains.

Settings

Match your cartridge

Switch the in- and output & adjust the gain on the front. The cartridge impedance can be set on the back with a push of a button.

Made in EU

High-quality materials

The new Step Up Box DS3 B is carefully designed and handmade in Europe.
