Gain ranges from 40dB to 65dB cater to a wide variety of cartridges, ensuring seamless integration with your Hi-Fi system and perfect volume matching with other audio sources. Pro-Ject Audio Systems’ unique potentiometer allows for continuous load impedance adjustment during playback, letting you find the optimal setting for your cartridge in real-time—an exclusive feature in the industry.
Balanced Signal Transmission
Achieve superior sound quality with balanced signal transmission using either the 5-pin mini XLR or standard XLR cables. Balanced transmissions, with hot and cold (+ and -) signals, deliver the same musical information through both channels. The Tube Box DS3 B processes these signals to eliminate any noise introduced during transmission, thanks to its audiophile-grade tube output and polypropylene capacitors, ensuring an extraordinary listening experience.
Interference-Free Performance
Balanced connections ensure that any noise from modern electronic interferences is effectively filtered out, preserving the purity of your music.
E88CC Vacuum Tubes
The E88CC tubes in the Tube Box DS3 B are known for their low noise and minimal microphonics. Enjoy a rich, detailed low end combined with warm, inviting highs.
Continuous Impedance Loading
Adjust the load impedance seamlessly during playback with the potentiometer, allowing for real-time fine-tuning of your audio setup.
