The Industry Leader In Affordable Analog Products
Pro-Ject Audio Systems was founded by one of Austria’s leading high-end audio distributors, Heinz Lichtenegger, in early 1991. A genuine music lover and a dyed-in-the-wool audiophile, Heinz challenged the common “cost-no-object” approach to analog audio equipment by manufacturing turntables, tonearms, and accessories at a reasonable price without compromising build quality or sonic performance.
HIGH-END TUBE SOUND
The Tube Boxes have been an integral part of our product portfolio for many years. Now, the new Tube Box DS3 B adds balanced in- and outputs to the beloved tube amplification. This precision tube phono preamplifier benefits from outstanding circuit technology from Dr. Sykora and uses ultimate components.
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.
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
