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!

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, both times the fully symmetrical gain stage can optimize the signal-to-noise ratios, feeding the fully passive and discrete RIAA equalization stage with the cleanest signal to work its magic on.

Entirely split passive equalization allows for better impedance matching and lower deviation from the ideal RIAA curve. The Phono Box DS3 B 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 circuit.

TRUE BALANCED CONNECTION

The symmetrical design is the fundamental standout feature! Connect your turntable via the 5-pin mini XLR cable or standard XLR cables and enjoy the benefits of our new True Balanced Connection. A truly balanced gain stage can extract the final musical information, effectively filtering out any noise from interferences stemming from our noisy, modern homes (household appliances, wifi & Bluetooth, power cables, audio amplifiers).

High-End Features

Limitless Loading

Steel & aluminium casework. Entirely discrete audio circuitry. Fully symmetrical gain stage. Split passive RIAA EQ. Dual mono. Balanced in & outputs. Stepless impedance matching.

True Balanced

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.

GOOD BUY
Color: Grey, Number of Items: 1
This is a good sturdy table. It is the perfect size for an end table or nightstand. The USB ports and Outlets really come in handy. It is made out of real wood which is rare, it is definitely worth money.

Good for small spaces.

Great size. Its medium/small. Not cheap looking which is great. It has space for our phone charger, a drink and a small lamp. (The one in the photo is too big) My fiance put it together within an hour, the instructions were easy to understand. It does not wobble but we do have it on wood. Its not heavy so it does slide around.
