Preamplifiers — Pro-Ject Pre Box S2 Analogue

The Pre Box S2 Analogue is a preamplifier from Pro-Ject, built with an exceptionally low distortion figure in a remarkably compact chassis. The Pre Box S2 Analogue brings Pro-Ject's considered engineering to a space-efficient line-level signal control format.

Key specs that matter

Two single-ended inputs and one single-ended output are provided. Gain is 8.5dBu. Input impedance is 15,000 ohms. Frequency response spans a wide 20Hz to 40,000Hz within plus-or-minus 3dB. Signal-to-noise ratio is a strong 100dB unweighted, with total harmonic distortion plus noise at an exceptionally low 0.0005% - an impressive figure for such a compact chassis. At a remarkably compact 103 x 36 x 120mm and just 0.405kg, the Pre Box S2 Analogue maintains a minimal, space-efficient preamplifier chassis.

Sound and use context

Expect exceptionally clean, transparent signal handling reflecting the near-immeasurable 0.0005% distortion figure combined with the strong 100dB signal-to-noise figure, packed into this remarkably compact chassis.
