High-Performance Pro-Ject Phono Box RS MM/MC Preamplifier

The Pro-Ject Phono Box RS stands out as an exceptionally flexible and sonically superior phono stage that delivers unparalleled value. This ultra-low-noise and ultra-low-distortion preamplifier caters to the discerning audio enthusiast, offering breathtaking performance courtesy of its dual-mono circuit topology and advanced design.

The Phono Box RS's adaptability is a key strength, as it can accommodate any phono cartridge. Users have the option to select a fixed gain setting or utilize the variable gain, which can be adjusted on the front panel to 40, 50, or 60 dB. Moreover, the innovative 'infinitely' variable impedance control, also located on the front panel, provides a continuously adjustable impedance range between 10 and 1200 ohms, allowing for seamless impedance adjustment during playback.

Enhancing the flexibility further, the Phono Box RS offers adjustable input capacitance via the rear panel settings, providing a choice of 100, 200, 300, 420, or 520 pF. This comprehensive array of adjustments ensures that the phono preamp can be perfectly tailored to extract the best performance from any phono cartridge.

The superb quality of the Phono Box RS is evident in its construction, which features premium components throughout, including the latest-generation SSM2019 audio preamplifier from Analog Devices as the input stage and a Linear Technology LT1010 as the high-current buffer stage. This attention to detail results in exceptionally low levels of distortion and noise, while the very low output impedance makes the unit insensitive to the selection of interconnect cables and lengths.

For even greater flexibility in the sonic signature, the Phono Box RS offers the option to select fully passive RIAA or DECCA equalization, further expanding the sonic possibilities. Additionally, the unit boasts fully balanced circuitry, with both XLR and RCA inputs and outputs, catering to a wide range of system configurations.

In conclusion, the Pro-Ject Phono Box RS is a remarkable phono stage that sets a new standard for performance and versatility in its price range. Its combination of advanced features, premium components, and meticulous design results in a phono preamp that elevates vinyl playback to new heights, delivering clear, detailed, and smooth sound that will captivate any audio enthusiast.
