Pro-ject Audio Systems - USA Phono Box DS3 B

True Balanced, Dual Mono & Fully Discrete Audiophile Phono Stage

A New Level of Balance

The New Phono Box DS3 B

At Pro-Ject, balanced connections were exclusive to our RS range of products until now. The Phono Box DS3 B model offers some of the high-end features of the Phono Box RS2 at an affordable price and trusted Pro-Ject quality. One of those is our new True Balanced Connection.

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 get stored in the memory. Perfectly match the Phono Box DS3 B to a wide variety of cartridges. 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!

Balanced By Nature

Cartridges are balanced signal transducers by nature! Due to the internal wiring of MM cartridges, you'll need a MC cartridge to access the entirety of that balanced signal. Together with our new True Balanced Connection cables you'll be able to access high-end features that were previously only available on the most expensive phono stages. And the best: any Pro-Ject turntable with RCA, miniXLR or 5P output can do it!

Unleash the full power

Phono Box DS3 B is ready for our new True Balanced Connection. Single-ended RCA connections, quite literally, only use half of your cartridge's output. With one of our new True Balanced phono cables and an MC cartridge you'll hear details and dynamics, previously exclusive to only the most expensive phono stages.
