Description
Tube Box S3 B
Crafted in Europe, the Tube Box S3 B by Pro-Ject Audio Systems features a robust aluminium chassis that protects against interference and vibration. Front-panel controls offer easy access to key settings, while dual turntable inputs add convenience for vinyl enthusiasts.
The sleek, compact form is available in silver or black, making it a stylish addition to any hi-fi system.
Balanced Signal Path
The "B" means Balanced – and that is where this phono stage shines. Using a symmetrical signal path via a 5-pin mini XLR input and balanced XLR outputs, it extracts musical detail while cancelling out noise.
This design ensures a purer, more dynamic sound, typically found in far more expensive equipment.
Flexible Cartridge Matching
With gain settings from 40 dB – 65 dB and ultra-low loading options like 50 pF and 10 Ohms, the Tube Box S3 B adapts to a wide range of MM and MC cartridges.
Each input stores its own settings, allowing seamless switching between turntables.
Whether you’re dealing with high-capacitance cables or fine-tuning your setup, this phono stage offers precision and ease.
