Pro-Ject Phono Box S3 B, Black

The Pro-Ject Phono Box S3 B is a versatile phono preamplifier designed to bring clean, detailed vinyl playback to both MM and MC cartridge setups, with a fully balanced signal path and compact, rigid steel and aluminium construction. Its fully discrete and symmetrical gain stage helps minimise noise and interference, while flexible cartridge loading and gain settings make it easy to match different cartridges and audio systems. With balanced 5-pin mini XLR input, XLR and RCA outputs, and a semi-passive RIAA equalisation stage, the Phono Box S3 B offers high-end features in a compact, easy-to-use design.

• Fully balanced phono stage with a symmetrical signal path for clean, low-noise vinyl playback. 
• Fully discrete gain stage uses individual components instead of integrated circuits for detailed signal amplification. 
• MM and MC compatible with flexible settings for a wide range of cartridges. 
• Adjustable input impedance from 10Ω to 47kΩ and capacitance from 50 to 400pF. 
• Four gain levels from 40dB to 65dB, with an additional 6dB available through XLR outputs. 
• 5-pin mini XLR and RCA inputs provide flexible turntable connectivity. 
• Balanced XLR and RCA outputs allow easy integration with different Hi-Fi systems. 
• Semi-passive RIAA equalisation and 20Hz subsonic filter help maintain accurate, controlled playback.
