RS232 Control Equipped with both single-ended RCA input sockets and balanced XLR inputs, the Amp Box RS2 offers flexible connectivity options. Input selection is easily controlled via the front panel or through RS232 integration. The amplifier’s gold-plated, isolated speaker terminals support a range of connection types, ensuring compatibility with a variety of speaker cables. Power Box RS2 For those seeking even greater performance, the optional Pro-Ject Power Box RS2 Amp can be added, featuring a linear power supply with a toroidal transformer for enhanced power stability and superior audio reproduction. The Cleanest Power Delivery The power supply plays a crucial role in the audio path, significantly influencing the overall sonic performance of an audio product. By integrating the Power Box RS2 Amp with your Amp Box RS2, you can optimise the power contribution and achieve superior sound quality. Features Power supply for Amp Box RS2 Replaces original “switching” power supplies Significant sound improvement Improved sound stage and detail resolution Cleanest power using non-switching power supply Soft start system avoids current inrush Audio type toroidal transformer Main isolating transformer with copper foil shielding Secondary voltage rectification with precise regulation High filtration capacity (40.000 μF) Low ESR capacitors Low noise components with surge protection Rigid aluminium casing protects against interference Available in silver or black Made in Europe Avoids Interference Penetration The linear power supply features a substantial toroidal transformer, which effectively prevents interference from the mains from affecting the audio component. This transformer offers a considerably higher power reserve than a standard power adapter, boasting a very low output impedance. When paired with extensive filtration capabilities, it effortlessly meets all power requirements. Enhanced Sound Quality This improved power delivery leads to noticeable enhancements in sound staging, deeper silences, and a greater resolution of fine details. These upgrades contribute to a significantly enhanced overall performance of each audio component. The Power Box RS2 Amp is crafted in Europe and is available in a choice of black or silver, with a full aluminium housing.
