Know before you buy
You can connect up to six components simultaneously. The unit features specific outputs for two 9V devices, three 18V devices, and one 15V device.
The Power Box DS3 Sources is specifically engineered for Pro-Ject components. It is not recommended for use with third-party equipment, as the voltage outputs and connector types are tailored to Pro-Ject's specific requirements.
Standard switching power supplies can introduce high-frequency noise into your audio signal. This linear power supply uses a toroidal transformer and advanced filtration to provide a cleaner, more stable current, which typically results in improved soundstage depth and better detail resolution.
Setup is straightforward; simply connect your compatible Pro-Ject components to the corresponding voltage outputs on the back of the unit. It features a soft-start system to manage current inrush, so no special maintenance or power-up sequences are required.
The rigid aluminum casing acts as a shield against electromagnetic and radio frequency interference. By isolating the internal components from external electrical noise, it ensures the power delivered to your audio gear remains as clean as possible.
Yes, the Power Box DS3 Sources supports universal input voltage, making it compatible with both 115V and 230V AC power standards found globally.
