High-end phono preamp with unique impedance matching

The lowest possible noise and distortion make this phono preamplifier something outstanding for real vinyl lovers.

Not only the breathtaking performance, but also the optimal adaptability to any pickup, thanks to the continuously adjustable impedance during playback, make this preamp a real highlight. Thanks to the best components, such as the input stages SSM2019 from Analog Devices and the high-current buffer stage LT1010 from Linear Technology, the Phono Box RS convinces with fantastic top marks for low noise and freedom from distortion. Due to the extremely low output impedance, the Phono Box RS is less sensitive to cable selection and lengths. You can choose between purely passive RIAA and DECCA equalization.

The fully symmetrical design guarantees outstanding sound quality via the XLR and RCA inputs and outputs. Never before have you been able to enjoy your valuable vinyl treasures as clearly, seamlessly and with as much detail as with the Phono Box RS!

Pro-Ject Phono Box RS - high-end phono preamplifier

Reference class phono preamplifier with unique impedance control

This ultra low noise and distortion preamplifier is made for the audio conniosseur and offers not only breathtaking performance but is capable of adapting to virtually any phono cartridge through variable impedance control. Impedance adjustment can be done while playback! Due to use of best parts, like SSM2019 from Analog Devices as input stages and Linear Technology LT1010 as high current buffer stage, Phono Box RS delivers ultra low levels of distortion and noise. Its very low output impedance makes it insensitive to selection of interconnect cables and lengths.

Fully passive RIAA and DECCA equalization is selectable. Phono Box RS offers fully balanced circuitry and both XLR and RCA inputs and outputs. All in all vinyl playback will never have sounded as clear, detailed and smooth, than with this superlative phono stage!
