Pro-Ject Power Box RS Uni 1-Way TT, with this new solution of the Pro-Ject Box Design Series or more specifically the Pro-Ject Box Design RS Series, the company Pro-Ject Audio Systems introduces the latest tuning option for record players. This is a universal linear power supply that is specially designed for turntables with heavy platters.

Pro-Ject Power Box RS Uni 1-Way TT as universal linear power supply unit

It is a well-known fact that the power supply is one of the critical components of a record player, which, unfortunately, is rarely given the attention it deserves, according to Pro-Ject Audio Systems.

It is a proven fact that the power supply is a very important component in an audio chain, as it makes a decisive contribution to the sound quality of a system, the Austrian company states.

The task of the new Pro-Ject Power Box RS Uni 1-Way TT is to significantly improve the sound of a record player.

Specially developed for turntables with heavy platters

The new Pro-Ject Power Box RS Uni 1-Way TT has been specially developed for turntables with a heavy platter. This applies to the Pro-Ject RPM 9 and Pro-Ject RPM 10 models, the Pro-Ject Signature 10 and Pro-Ject Signature 12 models, and the Pro-Ject Xtension 9, Pro-Ject Xtension 10 and Pro-Ject Xtension 12 solutions.

In addition, the new Pro-Ject Power Box RS Uni 1-Way TT is of course also compatible with a wide range of other Pro-Ject Audio Systems turntables, as long as they have a supply voltage of 15 V DC.

High-purity power supply free of switching power supplies

Pro-Ject Audio Systems uses a linear power supply with an oversized toroidal transformer at its heart. This has an effective shielding of copper foil between the primary and secondary windings to ensure the transmission of interference from the mains. In addition, the toroidal transformer offers significantly more power reserves than standard power supplies. A very low output impedance and a high capacitor capacity should ensure that there are no restrictions in the provision of power. For this purpose, a filter capacity of 10,000 μF and low ESR capacitors are used.

Another important feature is the so-called soft-start system, which avoids voltage peaks.

By the way, the Pro-Ject Connect it Power RS – TT 15V MiniXLR – 2.1 cable is part of the delivery.

The new Pro-Ject Power Box RS Uni 1-Way TT is available in black or silver. It measures 201 x 72 x 195 mm and weighs an impressive 4.8 kg.

Getting to the point

The new Pro-Ject Power Box RS Uni 1-Way TT is intended to provide an optimal power supply for record players. This power supply, designed as a universal linear power supply, is superior to any standard switching power supply, thanks to a high-purity power supply with enormous power reserves. This makes the new Pro-Ject Power Box RS Uni 1-Way TT ideal for turntables with particularly heavy platters.
