“Phono Box DS2 USB is a sophisticated phono stage based on a high-end passive/active ultra-linear phono equalization. MM and MC capability as well as ‘on-the-fly’ impedance adjustment and multiple capacitance settings make this a feature-rich, sound-first design. The two phono inputs and input selector allow enthusiasts to toggle between two turntable/cartridge combos with the push of a button. For the USB model, a low-noise, jitter-free A/D converter is used to convert the analog signal to a high-resolution digital format (PCM up to 192kHz or DSD 128). Via the USB output, it’s easier than ever to record your vinyl to digital. There is also an analog line-in to record other analog sources. Phono Box DS2 USB is housed in a chassis made of 2-layer metal for a simple, sleek look that shields the circuitry from the influence of mechanical or electromagnetic interference.” – Pro-Ject
