Double power for your turntable and phono preamp!

Power Box S3 Phono is an efficient and flexible power filter for your turntable and phono preamp. By moving the power supply from outside of the main component, unwanted noise and audio signal contamination is avoided. Clean energy makes a significant positive contribution to the sound quality. The two outputs are specifically engineered to power Pro-Ject turntables and phono preamplifiers. The sophisticated DC filtration can have a dramatic impact on the sound quality. In addition to the sonic improvements, Power Box S3 Phono also offers its users a more streamlined cable solution.
