Tube Box DS3 B Is the Latest Evolution of Pro-Ject's European-made Legendary Tube Phono Preamps

  • Dual mono balanced tube phono preamplifier
  • Enhance your analog system with high-end tube sound
  • Support for two turntables connected simultaneously with multiple cartridge options
  • Eliminate noise with a balanced XLR connection

High-End Tube Sound

Tube Boxes have been an integral part of Pro-Ject's product portfolio for years. The new Tube Box DS3 B adds balanced in/outs 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 setting is stored in 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 load options. This is necessary to find just the right load impedance for your cartridge. No other manufacturer implements this feature in this precise and extreme manner.

Balanced Signal Transmission

Connect your turntable either with the 5-pin mini XLR cable or standard XLR cables and profit from a balanced signal transmission. Symmetrical (a.k.a. balanced) transmissions consist of a hot and a cold (+ 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.

Key Features

  • 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.
  • Continuous Impedance Loading: Load impedance can be set continuously via potentiometer. It allows you to seamlessly adjust the impedance during playback.
  • Made in EU: The new Tube Box DS3 B is carefully designed and handmade with high quality materials in Europe.
