Free shipping: On all orders over 500 SEK
Experience cleaner and more dynamic vinyl sound with the Pro-Ject Phono Box S3 B – a compact, fully balanced phono preamplifier that brings high-end technology at an accessible price. This model introduces Pro-Ject's award-winning True Balanced Connection in the S series, providing exceptional noise reduction and a more open, deeper soundstage. Perfect for those who want to maximize the potential of their turntable, whether using MM or MC cartridges.
- True Balanced Connection – With a 5-pin mini XLR input, you get a fully balanced signal path that utilizes the full potential of the cartridge (especially with MC cartridges and compatible cables). This filters out noise from WiFi, Bluetooth, household appliances, and power cables – ideal for modern homes.
- Support for two turntables – Connect two different cartridges simultaneously and save individual settings for each input in memory.
- Fully discrete circuit design – No use of op-amps or integrated circuits – only carefully selected discrete components for symmetrical gain and semi-passive RIAA equalization.
- Flexible cartridge matching – Adjust impedance and capacitance on the front panel, including ultra-low values (10 ohm / 50 pF) for optimal matching.
- Subsonic filter – 20 Hz with 18 dB/octave to eliminate unwanted low-frequency disturbances.
- Robust construction – Steel and aluminum chassis for high rigidity and effective shielding against interference. Handmade in Europe.
