PHONO BOX DS3 B

THE INPUTS

As the Phono Box DS3 B is equipped with both balanced XLR inputs and outputs, it is also part of Pro-Ject’s True Balanced Connections concept. Connect your turntable via the 5-pin mini XLR cable or standard XLR cables and enjoy the benefits of the new True Balanced Connection, your analogue system can benefit from increased dynamics, less noise and improved signal-to-noise ratios.

THE OUTPUTS

Elsewhere in the Phono Box DS3 B design, the fully-passive and discrete 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 a fully discrete output stage (when using RCA outputs) or is connected to a fully discrete balancing stage for onward balanced connections.

NEW TECHNOLOGY INSIDE

The Phono Box DS3 B incorporates a true, fully balanced gain stage design. Whether you're using a single-ended RCA or balanced connection, both times the fully symmetrical gain stage can optimise the signal-to-noise ratios, feeding the fully passive and discrete RIAA equalisation stage with the cleanest signal to work its magic on. Entirely split passive equalisation allows for better impedance matching and lower deviation from the ideal RIAA curve.

ACCESSORIES AND VARIATIONS

The Phono Box DS3 B is finished in a steel chassis, covered by silver or black aluminium panels, for extreme rigidity and good electrical isolation. The neat minimalist aesthetic can be further enhanced by the addition of retro-inspired, magnetically installed wooden side panels (available separately). It also features an external power adapter, to keep the sensitive internal signals free from any interferences.
