The Phono Box DS3 B is a dual-mono, fully discrete moving magnet and moving coil phono stage with balanced inputs and outputs. With a host of customisable features, it offers exceptional value for money and brings a notable upgrade to any mid-/high-end analogue hi-fi system.

Key Features:

  • New balanced XLR in- & outputs
  • New 5-pin mini XLR balanced input
  • New fully symmetrical & discrete gain stage
  • New fully passive & discrete RIAA equalisation
  • New fully discrete audio circuitry - NO Op-amps!
  • MM & MC capable
  • Balanced & single ended in- & outputs
  • Dual mono design
  • Continously variable input impedance loading
  • Most precise MC cartridge matching
  • Superior low noise / low distortion
  • Trigger in- & output
  • Heavy aluminium casing protects against interference
  • Available in silver or black
  • Magnetic wooden side panels avaialable separately
  • Made in Europe

The Pro-Ject design team took the decision to employ discrete circuitry in the Phono Box DS3 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.

This philosophy for the best possible performance carries through to the variety of conveniently-placed features the Phono Box DS3 B has on offer. The phono stage can be connected to two turntables at the same time, and each input will save its previous settings in memory so the Impedance, Capacitance (for MM cartridges) and Gain will all be set as you switch between turntables. For MC cartridges, the continuously adjustable load-impedance dial on the front panel allows you to perfectly set the impedance to suit your cartridge and your ears.

As the Phono Box DS3 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.
