Product Details

It is a proven fact that a power supply is a very important part of the audio path and significantly contributes to the sonic quality of an audio product. In order to offer the possibility of improving sound quality, Pro-Ject designed the linear power supply Power Box DS Sources. It significantly enhances the sound quality of up to six Box Design components, like streamers, CD players, pre-amplifiers and also offers the possibility to connect a DC-driven turntable.

A linear power supply consists of a massive toroidal transformer with shielding between primary and secondary winding, which acts as an isolating transformer and avoids penetration of interferences from mains into the audio component. The built-in transformer has a much higher power reserve compared to the standard power adapter. It has very low output impedance and in combination with large filtration capability it can easily manage all power needs. Sound staging, darkness of silent backgrounds and small detail resolution will improve strongly and contribute to a far better overall performance of each component.

Six standard connection cables are included in delivery.

The following interconnect power cables are supplied in box:

2 x 9V (1.3mm connector) – a detailed list of supported Pro-Ject devices can be found in the manual and product information in the Downloads section below

3 x 18V (2.5mm connector) – a detailed list of supported Pro-Ject devices can be found in the manual and product information in the Downloads section below

1 x 15V (2.1mm connector) – to connect a 15V DC driven Pro-Ject Audio Systems turntable.
