Pro-Ject Phono Box RS Phono Pre Amp (MM/MC)

The Phono Box RS represents Pro-Jects first foray into the world of high-end electronics. Its an ultra-low noise and distortion Pre Amplifier made with the audio connoisseur in mind. With this in mind, it offers not only a breathtaking performance, but is also capable of being fine-tweaked to suit a wide variety of premium pick-up cartridges. The Phono Box RS has a unique variable impedance control on the front panel which means impedance adjustments can now be done during music playback!

Due to the use of some of the finest quality components available, like the SSM2019 pre-amplifier from Analog Devices on the input stages and Linear Technology's LT1010 as a high current buffer stage, the Phono Box RS delivers ultra-low levels of distortion and noise. Its very low output impedance makes it insensitive to the selection of interconnect cable types and lengths.

Fully-passive RIAA and DECCA equalisation is selectable via the stylish switches on the front panel, as is the output Gain (on XLR and RCA) and a handy Mute function (the F/V switch relates to switching on and off the variable impedance control). Further cartridge adjustment is done via the familiar dip-switch layout on the back panel. The Phono Box RS offers fully balanced, dual-mono circuitry and both XLR and RCA inputs and outputs, earning it recognition in a wide variety of high-end systems.
