Pro-Ject Phono Box S3

he Phono Box S3 B is an entry-level phono preamplifier that offers a fully balanced design in a neat, small package. We’ve packed this tiny chassis to the brim with high-end features. One of those is our new True Balanced Connection. At Pro-Ject, balanced connections were exclusive to our RS range of products until now. The Phono Box S3 B brings those features to an incredible new entry level.

True High-End For the New Entry-Level

Our Phono Box S3 B comes in complete new casework. The bigger size enabled us to bring a completely new feature set that was never seen before in this price range. The new steel & aluminium case also offers very high rigidity and isolation against outside interferences, which is essential for the new technology inside. Connect up to two turntables simultaneously – all parameters for each input get stored in the memory. You can perfectly match the Phono Box S3 B to a wide variety of cartridges. Use the gain setting to accurately match the output to other sources like CD players or streaming devices. Ultra-low values like 50 pF or 10 ohms allow you to account for all situations.
