    Cleanest Power for Ultimate Sound Quality from RS-Series Gear

    Get maximum performance and ultimate sound quality from your Pro-Ject RS-series Box Design components with the Pro-Ject Power Box RS. The super clean and regulated specially designed power supply significantly enhances the sound quality of the CD Box RS, DAC Box RS, Head Box RS, Pre Box RS, Pre Box RS Digital and Stream Box RS.

    Choose the Power Box RS Uni 1-way to power one of these components or the Power Box RS Uni 4-way to power up to four RS-series components.

    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. You will notice a significant improvement with the Power Box RS compared to the standard power supply that comes with your RS-series component.

    Linear Power Supply Design

    The linear power supply used in the Power Box RS 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 RS-series power adapter. It has very low output impedance and in combination with large filtration capability it can easily manage all power needs.

    Purest, Cleanest Power

    The Power Box RS provides the purest and cleanest power using a non-switching power supply. The soft start circuitry avoids current inrush in primary winding. The power supply features secondary voltage rectification with precise regulation and high filtration capacity (10,000 µF). It uses low-ESR capacitors and low-noise components with surge protection.

    Soundstaging, the 'darkness' of silent backgrounds and small detail resolution will improve strongly and contribute to a far better overall performance of each component.
