Pro-Ject Power Box Phono S3 – Turntable and Phono Preamp optimally powered

An elegant solution for the power supply of the phono chain, i.e. record player and phone preamplifier, should be available with the latest solution of the Pro-Ject Box Design Series, the Pro-Ject Power Box Phono S3.

The new Pro-Ject Power Box Phono S3 represents a special solution of the Pro-Ject Box Design Series, this can be said clearly. It is a power supply unit that provides clean power to the two essential components for record playback, namely the phono preamplifier and the record player, provided these are solutions from Pro-Ject Audio Systems.

Pro-Ject Power Box Phono S3 – Central power supplier

Pro-Ject Audio Systems rightly calls this an all-in-one power supply for the entire phono set-up, because instead of two power supplies, there is only one in the power strip, namely an 18 V 1,000 mA power supply for the Pro-Ject Power Box Phono S3 itself. This in turn supplies a phono preamplifier with 18 V DC and the record player with 15 V DC.

This solution is therefore compatible with a wide range of Pro-Ject Box Design Series phono preamplifiers, as well as with almost all current record players from Pro-Ject Audio Systems.

Free from sound-damaging effects

According to Pro-Ject Audio Systems, the new Pro-Ject Power Box Phono S3 increases the quality of playback simply because the power supply can be placed in such a way that it has no negative effect on the actual signal processing.

In addition, this solution has two tailor-made outputs for supplying the record player or the phono preamplifier and relies on sophisticated DC filtering, linear voltage regulation and thus provides a low-noise, stable power output.

Compact Pro-Ject Box Design S3 Series solution

As befits a Pro-Ject Box Design S3 Series solution, the new Pro-Ject Power Box Phono S3 presents itself as a very compact solution with an aluminium housing in either silver or black. With dimensions of 103 x 37 x 106 mm, this solution weighs 370 g.

Prices and availability

The new Pro-Ject Power Box Phono S3 should be available in specialist shops within the next few days at a recommended retail price of € 179,-. Pro-Ject Audio Systems would like to emphasise once again that this is a solution that is manufactured exclusively and entirely in Europe.

Getting to the point

The new Pro-Ject Power Box Phono S3, which is now available from specialist dealers, is dedicated to the task of supplying phono preamplifiers and record players with a single power supply. Pro-Ject Audio Systems offers an extremely practical solution that also raises the quality of playback to a new level.
