Pro-Ject Tube Box DS3 B True Balanced Phono Preamplifier

Description

Pro-Ject Tube Box DS3 B True Balanced Phono Preamplifier

The Pro-Ject Tube Box DS3 B True Balanced Phono Preamplifier is powered from an external adapter. It is important to keep all the parts which can radiate electromagnetic fields out of the amplifier range.

This is the reason why Pro-Ject use an outboard power supply. Due to legal requirements, this power supply must be a switch mode type with guaranteed stand-by mode power consumption 0,1W. An outboard power supply with linear construction is even better, because it can offer much cleaner power.

When you want to manufacture such clean and really high-end power supplies, you have to use a transformer with a very low core saturation and preferably with shielding between primary and secondary windings.

Balanced XLR – Interference free

A balanced connection can extract the final musical information, effectively filtering out any noise from interferences stemming from our noisy, modern homes.

E88CC Vacuum tubes

The E88CC tubes perform with low noise and microphonics. Enjoy the detailed low end paired with warm highs.

Settings – Continously impedance loading

Load impedance can be set continuously via potentiometer. It allows you to seamlessly adjust the impedance during playback

Made in EU With High-quality materials

The new Tube Box DS3 B is carefully designed and handmade in Europe.

Cartridge loading options

You can connect two turntables at the same time & easily set everything on the front plate.

Each input settings are stored in the memory. Large ranges from 40dB up to 65dB are possible. You can perfectly match it with a wide variety of cartridges and integrate it into the rest of your Hifi system, matching the volume levels accurately to other sources like CD players or streaming devices.

Load impedance can be set continuously via potentiometer, a system invented by Pro-Ject Audio Systems. It allows you to seamlessly adjust the impedance during playback and immediately assess the impact of different loading options. This is necessary to find just the right load impedance for your cartridge. No other manufacturers implement this feature in this extreme way.

Balanced signal transmission

Connect your turntable either with the 5-pin mini XLR cable or standard XLR cables & profit from the balanced signal transmission.

Symmetrical, also called balanced, transmissions consist of a hot and a cold (also called + and -) signal. Both signal chains effectively carry the same musical information. The Tube Box DS3 B can extract the final musical information out of the +/- signals and remove all noise that was potentially added along the transmission. All components including tube output and polypropylene capacitors are audiophile grade and guarantee a breathtaking sound experience.
