Pro-Ject Tube Box DS3 B

Tube Box DS3 B Dual mono balanced tube phono-preamplifier Made In Europe         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 E88CC Settings Made in EU Interference free A balanced connection can extract the final musical information, effectively filtering out any noise from interferences stemming from our noisy, modern homes. Vacuum tubes The E88CC tubes perform with low noise and microphonics. Enjoy the detailed low end paired with warm highs. Continously impedance loading Load impedance can be set continuously via potentiometer. It allows you to seamlessly adjust the impedance during playback High-quality materials The new Tube Box DS3 B is carefully designed and handmade in Europe.         REVIEW & AWARDS Pro-Ject Tube Box DS3 B Phono Stage Review - Read More "Pro-Ject's Tube Box DS3 B is a fabulous phono amplifier that delivers hear-through clarity, a defining characteristic of an accomplished tube design. Its inherently musical nature brings out the best in your record collection, smoothing out the spikiness from poor recordings without introducing intrusive colour to great ones. Well-built and competitively priced, it easily holds its own in a system built around far more expensive components. Sonically, it performs at a level that precious few of its competitors can rival. Partner it with a neutral and transparent amplifier for a wonderful analogue audio experience." - John Pickford   Pro-Ject Tube Box DS3 B Phono Preamp - Read More "While the DS3 B’s treble could occasionally exhibit a certain sharpness, this was largely record-dependent. And while the low-end might not have possessed the raw power or subtlety of its pricier counterparts, it still managed to deliver a satisfyingly robust bass response. At $1,099, the Pro-Ject Tube Box DS3 B phono preamp is an outright steal and a sonic sorcerer all its own, no non-vinyl stimulants required. If your holiday budget allows further investigation, check it out. " - Ken Micallef    Review: Pro-Ject Tube Box DS3 B- Noise-free vinyl sound - Read More "The Pro-Ject Tube Box DS3 B is not only a flexible and user-friendly phono stage. The amplifier opens up the sound of vinyl records in exemplary fashion, sounding resolved, detailed, silky smooth and ear-friendly. Tube Box is a great value for money, especially for those who can benefit from the balanced signal routing from input to output. Noise is minimised and the fine sound is infectiously attractive, no matter what kind of music is coming out of the grooves. The Pro-Ject Tube Box DS3 B is a well-playing alternative to a Rega Aria, Electrocompaniet ECP2 II, Primare R35 and Hegel V10." - Lasse Svendsen     SPECIFICATIONS Tube assembly 2x E88CC / 6922 Input impedance stepless 10-1000 Ohms, fix 47 kOhms Capacitance 50 / 150 / 300 / 400 pF Gain (+6dB using XLR Out) 40 / 45 / 50 / 55 / 60 / 65 dB Output voltage typically 500 mV/1kHz at 5mV/1kHz (at 40dB) Signal-to-noise ratio >87dBV - ‚A‘ weighted THD < 0,03% RIAA curve accuracy +/- 0,5dB/20Hz - 20kHz Subsonic filter at 20Hz with 18dB/octave Input 1x 5-pin mini XLR / 1x pair XLR / 1x pair RCA phono Output 1x pair RCA, 1x pair XLR Power supply 18V/1000mA DC Power consumption max 750 mA DC / < 0,5 watt standby Dimensions W x H x D 206 x 70 x 194 mm Weight 1560g (without power supply)
