PRO-JECT BOX DS3B PHONO PREAMP

Versatile

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.

B is for Balanced

Some turntables offer balanced or RCA outputs. 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.
