The PRTBS2 Tube Box S2 offers a wide range of input impedance settings, allowing users to optimize the phono preamplifier for their specific cartridge. The impedance can be adjusted using a simple switch located on the rear panel, providing flexibility and versatility.

The phono preamplifier also features a selectable gain setting, which can be switched between 40dB and 60dB to accommodate different cartridge sensitivities. The gain can also be toggled between MM and MC settings, making the PRTBS2 Tube Box S2 a universal solution for both moving magnet and moving coil cartridges.

The PRTBS2 Tube Box S2 is built with the finest components, including gold-plated RCA connectors, an aluminum chassis, and a high-quality power supply. The aluminum chassis not only looks great but also effectively shields the sensitive electronic components from external interference. The power supply features a low-noise toroidal transformer, which ensures a stable and clean power supply to the phono preamplifier circuit.

The PRTBS2 Tube Box S2 is a true audiophile component that offers a rich, warm, and detailed sound reproduction. Its tube-based design adds a unique character and personality to the music, making every listen an enjoyable experience.
