Pro-Ject Tube Box DS3 B Balanced MM/MC phono pre-amplifier

Highlights:
• Precision tube phono amplifier with balanced inputs and outputs
• Cartridge loading options for two connected turntables
• Large adjustable gain from 40dB to 65dB
• Impedance control adjustable during playback
• Balanced signal transmission for noise-free sound
• High-end components and tube output for an impressive sound experience

The Tube Box DS3 B is the latest addition to our Tube Box range, which has been an integral part of our product portfolio for many years. This precision tube phono amplifier features balanced inputs and outputs and benefits from unique circuit technology developed by Dr. Sykora, combined with ultimate components.
With the possibility of connecting two turntables at the same time and easy setting on the front panel, you can store settings for each input in memory. Gain ranges from 40dB up to 65dB make it possible to precisely match different cartridges and integrate it seamlessly into your HiFi system. The load impedance is continuously adjustable via potentiometer, a unique feature from Pro-Ject Audio Systems that allows you to adjust the impedance during playback and assess the effect of different settings.

Balanced Signal Transfer: Connect your turntable either with 5-pin mini XLR cable or standard XLR cables and enjoy the balanced signal transfer. The symmetrical transmission removes noise that has potentially been added during the transfer and ensures that all components, including tube output and polypropylene capacitors, are of audiophile quality, guaranteeing a breathless sound experience.
