Pro-Ject MC Step-Up Box S3 Passive Step-Up Transformer - Black
A Sound Upgrade for Your Mc Cartridge
The output level of MC cartridges is very low, compared to a MM (Moving Magnet) one it is about 10x lower, which means, you need a special phono amplifier. A higher gain is needed to utilize the signals, which can result in a higher noise level and distortion. The Pro-Ject MC Step Up Box S3 is the solution.
Lively, Dynamic, and Natural
The MC Step Up Box S3 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 corresponding decrease is current.
As there is no amplification, the MC Step Up Box S3 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.
A cartridge impedance matching button on the back allow two different settings (10-40Ω and 40-150Ω).
Premium RCA Terminals
The MC Step Up Box S3 has gold plated input and output RCA terminals for optimum signal transmission. It also boasts a solid full aluminum housing. Due to the timeless design and rigid aluminum casework, the MC Step Up Box S3 is built for eternity.
