Description

The Project 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.

Symmetrical and Discrete Circuit

The Pro-Ject design team decided to employ fully symmetrical and discrete circuitry in the Phono Box S3 B gain stage. Discrete circuits involve no operational amplifiers (op-amps), thus resulting in a more neutral, natural, dynamic, and vivid sound.

They are more complicated to put together and involve a greater variety of components, but when utilised in a well-organised electrical layout, they produce true high-end sound.

Impedance and Gain Options

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

True Balanced Connections

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 or specially designed moving magnet 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.

This requires engineering never before seen at this price point, opening up iconic mid-level turntables, such as the Debut Pro, to the benefits of True Balanced Connections.

RIAA Equalisation

Elsewhere in the Phono Box S3 B design, the semi-passive RIAA equalisation stage is optimised for absolute accuracy and signal integrity. Depending on the outputs you are using, this stage is then either directly fed to the output stage (when using RCA outputs) or is connected to a balancing stage for onward balanced connections.

Minimalist Design

The Phono Box S3 B has a steel chassis, covered by silver or black aluminium panels, for extreme rigidity and good electrical isolation. The neat minimalist aesthetic allows for good spacing between controls on the front panel and connections on the back panel, despite its smaller size. It also features an external power adapter, to keep the sensitive internal signals free from any interferences.
