Product Description

Pro-Ject Power Box RS Phono has been specifically designed to upgrade the Phono Box RS, by improving its power supply.  By optimising the power supply it manages to deliver the cleanest high-quality power source to the phono pre-amplifier.


The Pro-Ject Power Box RS Phono uses a Lithium-Ion battery power output to fully isolate, by means of physically separating the mains power from the pre-amp, which reduces interference and noise during playback for optimal sound quality. The linear power supply uses advanced Lithium Polymer batteries, with one assigned for each channel, and a playback duration of 4 hours, approximately.


With an estimated charging time of 4 hours, the unit manages such a fantastic battery life due to its smart microprocessor controlling the charging electronics.  To keep the unit user-friendly it features status indicator LEDs on the front panel and similar to whole RS range, it is available in a black or silver.
