Balanced connections were exclusive to Pro-Ject's RS range of products until now.
The Phono Box DS3 B offers some of the high-end features of the Phono Box RS2 at an affordable price with astounding sonic quality. It features the 'True Balanced Connection', which, in combination with a Pro-Ject turntable with a 5-pin balanced output and 5P to XLR cable, can achieve a totally balanced connection, minimising noise and delivering a breathtaking analogue signal.
High-End Features and Limitless Loading Options
The Phono Box DS3 B employs a steel chassis enveloped by aluminium panels. This construction offers very high rigidity and isolation against interferences, which is essential for the new technology inside. Magnetic wooden side panels are available separately as add-ons. You can connect up to two turntables simultaneously – all parameters for each input are stored in the unit.
The Phono Box DS3 B perfectly matches to a wide variety of cartridges in real time. Load impedance can be set continuously via a potentiometer, a system invented by Pro-Ject Audio Systems, to adjust the impedance during playback and assess the impact of different loading options in real-time. No other manufacturer implements this feature as elegantly!
A Technical Deep Dive
The Phono Box DS3 B incorporates a true, fully balanced gain stage design. Whether you're using a single-ended RCA or balanced connection, 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. The Phono Box DS3 B also uses fully discrete audio circuitry. A discrete circuit is composed of disparate, individual electronic components, also called discrete components. Years of experience have proven that even the best Op-Amps do not come close to the neutral, natural, dynamic, and vivid presentations of discrete circuits.
