Product Description

Phono Box S3 B

Pro-Ject

True High-End For the New Entry-Level

The 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. 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.

The New Phono Box S3 B

The 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.

Balanced By Nature

Cartridges are balanced signal transducers by nature! Due to the internal wiring of MM cartridges, you'll need to upgrade your turntable with an MC cartridge to access the entirety of that balanced signal. Together with our new True Balanced Connection cables you'll be able to access high-end features that were previously only available on the most expensive of phono stages. And the best of all: any Pro-Ject turntable with RCA, miniXLR or 5P outputs can do it!

Das Produkt liefert den üblich hervorragenden Klang, den man von der Firma erwartet. Durch den symmetrischen Aufbau verbessert sich die Wiedergabe, insbesondere in punkto Brumm und Rauschfreiheit. Hat sich wirklich gelohnt, diesen Vorverstärker zu erwerben.

Audio comes through perfectly, very open and clean, no added layers of warmth or other noticeable adjustments to the sound.Easy to install with a wide range of options to support almost any MM and MC cartridges, and even allows full balanced audio connection from turntable to the amplifier!Although marketed as “mid-range”, I think this is might be the perfect “end-game” phono stage for most people!
