Pro-Ject Power Box S3 Phono

Power Supply Upgrade for Pro-Ject Phono Preamps (18V) & Turntables (15V, DC Only)

Power Box S3 Phono is a very efficient and flexible power filter for your turntable and phono preamp. By separating the power supply from the main component, noise and signal contamination are avoided. It is no secret that clean, steady power contributes significantly to the sound quality of audio components.

An Instant Upgrade for Turntables & Phono Preamps

The two outputs are specifically engineered to power Pro-Ject turntables (15V DC only!) and phono preamps (18V). Sophisticated DC filtration allows your turntable & preamp to perform their best. Expect greater speed stability from your turntable and a lower noise floor from your phono preamp, amounting heightened clarity and resolution in analog playback. In addition to the sonic improvements, Power Box S3 Phono also helps with cable/PSU management by eliminating the need for turntable & phono preamp wall-wart power supplies.
