The Phono Box S3 B is a compact, affordable moving magnet and moving coil phono stage with dual-mono layout, discrete circuitry and balanced inputs and outputs. With its spacious, minimalist design layout, it is easily customisable to suit any connected cartridge, and offers unrivalled value for money and performance when connected to any matching analogue hi-fi system.

Key Features:

  • New 5-pin mini XLR balanced input 
  • New balanced XLR outputs 
  • New fully symmetrical & discrete gain stage 
  • New easy settings adjustment on the faceplate 
  • MM & MC capable 
  • Dual mono design 
  • Semi-passive RIAA equalization 
  • Superior low noise / low distortion 
  • Aluminium casing protects against interference 
  • Available in silver or black 
  • Made in Europe 

The Pro-Ject design team took the decision to employ fully symmetrical and discrete circuitry in the gain stage of the Phono Box S3 B. Discrete circuits involve no operational amplifiers (op-amps), and the result is a more neutral, natural, dynamic, and vivid sound. They are more complicated to put together and involve a greater variety of components, but the result when utilised in a well-organised electrical layout is a true high-end sound.

The Phono Box S3 B is extensively customisable so suit the moving magnet or moving coil cartridge it is connected to. With five Impedance (Ω), four Capacitance (pF) and four Gain options on offer, there are very few cartridges this box of tricks cannot accommodate.

As the Phono Box S3 B is equipped with both balanced inputs and outputs, it is also part of Pro-Ject’s True Balanced Connections concept. By connecting to a turntable with a moving coil cartridge and using one of Pro-Ject’s balanced connection cables, your analogue system can benefit from increased dynamics, less noise and improved signal-to-noise ratios. Going true balanced is like hearing parts of your music that were not there before.
