Enhanced Design and Build Quality

Housed in a new, larger steel and aluminum chassis, the Phono Box S3 B offers increased rigidity and effective isolation from external interference. Available in silver and black finishes, it seamlessly integrates into any hi-fi setup.

Balanced Connections for Superior Sound

The 'B' in Phono Box S3 B stands for 'Balanced.' It supports balanced connections, allowing you to upgrade to true balanced operation with a moving coil (MC) cartridge on most Pro-Ject turntables. Balanced transmissions utilize both hot and cold (positive and negative) signals, effectively carrying identical musical information. A true balanced gain stage extracts the final musical details from these signals while minimizing hum and noise, a technique commonly used in professional recording studios.

Discrete Circuitry for High-Fidelity Audio

The gain stage of the Phono Box S3 B features a fully discrete layout, meaning it is composed of individual electronic components rather than integrated circuits. This design choice, though more costly and time-consuming, results in superior sound quality, providing a more authentic and detailed audio reproduction.

Semi-Passive RIAA Equalization

After processing the balanced signals independently, they are combined and sent through a semi-passive RIAA equalization stage. Maintaining a fully symmetrical gain stage optimizes the signal-to-noise ratio and minimizes interference, ensuring the equalization section receives an optimal signal for precise audio reproduction.

Versatile Compatibility and User-Friendly Features

The Phono Box S3 B is compatible with both moving magnet (MM) and moving coil (MC) cartridges, offering flexibility for various turntable setups. It provides adjustable settings to accommodate different cartridge types and includes aluminum buttons for easy operation.
