Universal linear power supply for 15V DC turntables • specially developed for heavy-platter models • audio-grade toroidal transformer • 10,000 µF filtration • soft start system • silver or black finish
The Pro-Ject Power Box RS Uni 1-Way TT is a dedicated linear power supply engineered to elevate the performance of compatible 15V DC Pro-Ject turntables. Designed especially for models with heavier platters, it replaces a standard switch-mode adapter with a far more substantial power platform built around a shielded toroidal transformer, precise voltage regulation, and generous filtration capacity. The result is cleaner power delivery, lower interference, and a more refined analog presentation.
For serious analog listeners, upgrading the power supply can be one of the most effective ways to improve a turntable’s composure, silence, and low-level detail retrieval.
Massive linear power architecture — unlike a compact switch-mode adapter, this unit uses a substantial linear supply topology with a much larger transformer and power reserve to better satisfy dynamic current demands.
Precise regulation and filtration — secondary voltage rectification is paired with precise regulation, 10,000 µF of filtration capacity, and low ESR capacitors for lower noise and stronger stability.
Engineered for lower interference — the transformer’s copper foil shielding and low-noise components with surge protection are part of a design aimed at preserving low-level analog information.
In a well-matched system, the Pro-Ject Power Box RS Uni 1-Way TT can contribute to darker backgrounds, stronger sound staging, and more apparent low-level detail from a compatible turntable.
It is a linear power supply upgrade for compatible Pro-Ject turntables that use a 15V DC supply voltage.
No. It was specially developed for heavy-platter models, but it is also compatible with other Pro-Ject turntables that use 15V DC power.
It uses a larger linear supply with a toroidal transformer, soft start system, precise regulation, and much higher filtration capacity for cleaner power delivery.
Yes. Pro-Ject specifies that both the standard 3-pole connection cable and the connection cable from the power supply to the turntable are included.
No. Pro-Ject specifically notes that it should not be used with Phono Box RS.
