Pro-Ject Audio Systems Tube Box DS2

 

 

Our precision Tube Box DS2 phono preamplifier benefits from outstanding circuitry design by the brilliant Czech engineer, Dr. Bohumil Sykora. Compatible with most MM & MC cartridges on the market, it offers two turntable inputs so enthusiasts can easily toggle between two different turntable/cartridge combos. Continuously adjustable (‘on-the-fly’) input impedance for low output MC cartridges is a must-have feature that allows you to ‘tune’ the loading to achieve the sonics that best suit your system and your ears. Other features include input capacitance for MM cartridges and a switchable subsonic filter to stave off mechanical noise. All components including the tube output stage and polypropylene capacitors are audiophile-grade and guarantee a breathtaking sonic experience.

• Suitable for MM and MC cartridges
• Precise RIAA equalisation
• Ultra low noise circuitry
• Selection between 2 phono inputs & 2 line outputs
• Dual mono circuitry for optimized channel separation
• Selectable input impedance (for MC: fixed or variable)
• Selectable input capacitance (for MM)
• Selectable subsonic filter
• Gold-plated RCA in & outputs
• Sandwich alu/metal casing protects from vibrations and electromagnetic interference
• Finishes: silver or black, with/without wooden side panels
