The Cabinet is made of metal and a thick brushed aluminum front panel is decorated in a minimalist style. In its centre is the only knob to adjust the volume, and on the right there are two buttons for input selection with corresponding led indication.


In the device used perfect accessories with a low noise level, and its Assembly is designed to minimize the length of audiotape. The volume control is made on accurate potentiometer and provided with actuators for remote control. Pro-Ject Stereo Box S Phono has four inputs: three linear and one that is designed to connect a MM-pickup of the turntable. Scheme Phono stage built-in amplifier for precision RIAA-compensation and noise level is not inferior to individual high-end devices.


Pro-Ject Stereo Box S Phono is also equipped with two stereo outputs. One of them, RCA jacks, is adjustable, that is, the signal can be fed to an external amplifier or active speaker system, do not have their own volume control.
