Linear Power Supply for 15V DC Turntables
Meet the Power Box RS Uni 1-Way TT
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.
15V DC Turntables Linear Power Supply Heavy-Platter Ready Toroidal Transformer 10,000 µF Filtration
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.
Highlights & Benefits
-
Specially developed for demanding turntables — Pro-Ject designed this model specifically for heavier-platter decks such as RPM, Xtension, and Signature line turntables.
-
Cleaner power than a standard adapter — the non-switching linear design is intended to reduce noise and interference reaching the turntable.
-
Audio-grade transformer design — a toroidal transformer with copper foil shielding helps isolate the turntable from mains-borne contamination.
-
Soft start protection — the integrated soft start system helps avoid current inrush in the primary winding.
-
High current capability — rated at 15V / 3A maximum, it offers substantially greater power reserve than a typical stock wall supply.
-
Performance-focused upgrade path — the Pro-Ject Power Box RS Uni 1-Way TT is an ideal step for listeners who want more stable, more sophisticated power behind a serious analog front end.
Technology & Design
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.
FAQ — Power Box RS Uni 1-Way TT
What is this product designed to do?
It is a linear power supply upgrade for compatible Pro-Ject turntables that use a 15V DC supply voltage.
Is it only for heavy-platter turntables?
No. It was specially developed for heavy-platter models, but it is also compatible with other Pro-Ject turntables that use 15V DC power.
What makes it different from a standard adapter?
It uses a larger linear supply with a toroidal transformer, soft start system, precise regulation, and much higher filtration capacity for cleaner power delivery.
Does it include the connection cables?
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.
Can it be used with Phono Box RS?
No. Pro-Ject specifically notes that it should not be used with Phono Box RS.
