Pro-Ject Phono Box S3
The Phono Box S3 B is a phono preamplifier that offers a fully balanced design in a neat, small package. Weāve 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 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 ā 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.
FULLY DISCRETE AND SYMMETRICAL GAIN STAGE
The new Phono Box S3 B gain stage uses a fully discrete layout. A discrete circuit is composed of disparate electronic components, and individual devices. The amplifier section is built of single parts and doesnāt use any integrated circuits! That makes for an extended and more costly design process but results in the best sound quality. The fully symmetrical gain stage can optimize the signal-to-noise ratios, feeding the semi-passive, RIAA equalisation stage with a clean signal to work on.
TRUE BALANCED CONNECTION
The symmetrical design is the fundamental standout feature! Connect your turntable via the 5-pin mini XLR cable and enjoy the benefits of a balanced signal path. A truly balanced gain stage can extract the final musical information, effectively filtering out any noise from interferences stemming from our noisy, modern homes (household appliances, wifi & Bluetooth, power cables, audio amplifiers).
