RS-Line

The Phono Box RS is an ultra-low noise and distortion-free phono pre-amplifier for Moving Magnet (MM) and Moving Coil (MC) cartridges, made with the sophisticated audiophile in mind. The result is a device that not only offers a breath-taking performance, but is also extensively adjustable to work with any type of pick-up cartridge.

Internally, the Phono Box RS uses only the finest available components throughout in dual-mono configuration - like the SSM2019 pre-amplifier module from Analog Devices on the input stages, and Linear Technology's LT1010 as a high current buffer stage - which allows for a very clean sound, free of unwanted noise. The Phono Box RS is then connected into a system via either RCA or XLR connectors, making it one of the most affordable high-end balanced phono stages on the market. Due to the very low output impedance of the phono stage, it is easy to pair with a wide variety of quality cables.

For cartridge matching, there is an extensive list of settings adjustment available. On top of the usual Gain and Capacitance adjustments, the Phono Box RS boasts a fully adjustable dial for attenuating the Input Impedance. This allows for perfect matching with any Moving Coil cartridge on the market, and it can even be adjusted during playback to tailor the sound perfectly to your preference. To further suit individual tastes, there is also an option to choose between fully-passive RIAA or DECCA equalisation curves.

With the Phono Box RS, vinyl playback will never have sounded as clear, detailed and smooth than with this superlative phono stage...
