Power Box RS Phono: Phonoklang on the highest level!
At Pro-Ject Audio Systems, we believe that the power supply is a very important part of the audio chain and makes a significant contribution to the sound quality of an audio device. On the one hand, to ensure the maximum reproduction quality and, on the other hand, the complete separation of the phono preamplifier from the mains, the Power Box RS Phono with battery power was created. The power supply quality is particularly crucial if the signals to be amplified are very small. A low-output MC pickup typically has an output voltage of 0.2mV = 0.0002V. Such signals are highly sensitive to interference signals from the power grid.
How does the Power Box RS Phono work?
If the Power Box RS Phono is connected and switched on with the Phono Box RS, then only the battery connection to the Phono Box RS exists. Since the power supply unit and the charging unit are physically separated, disturbances from the mains supply can not be harmful to the sound. If the battery charge falls below a certain level, further playback could damage the batteries. Therefore, the charging electronics is automatically active, the charging status is indicated by LEDs on the front panel. The playback will continue, but the advantage of a complete disconnection from the mains will not exist for the period of loading. Although this is the biggest advantage temporarily not exist, the battery acts as a filter and the sound quality is still far better than with the standard power supply. As soon as the batteries are fully charged, the charging electronics are automatically disconnected and the Phono Box RS is only supplied with power via the batteries.
