RS Line

The development of Pro-Ject's RS Series of Box Design electronics has sparked the creation of a series of power supply upgrades for the various sources, amplifiers and accessories within the range. As part of this development, Pro-Ject have also kept one eye on their coveted range of turntables by creating a high-quality link cable that allows for the Power Box RS UNI 1-Way or Power Box RS UNI 4-Way to be connected to one of their high-end DC-powered (15V) turntables.

The Power Box RS TT-Lead is a high-quality shielded cable that includes a linear voltage regulator, for stepping down the clean 20V output from the power supply to 15V, so a Pro-Ject turntable can accept the input. The regulator not only steps down the voltage, but it also decreases internal impedance's within the cable to keep the power signal consistent.

There are many advantages to be gained from upgrading the power supply that was supplied with your turntable, including improved motor performance and efficiency. So by providing this, owners of high-end Pro-Ject turntables can now elevate their listening experience even further.

The Power Box RS TT-Lead comes in two types, one for Pro-Ject's mid-range of turntables, and one for the high-end designs (see FAQ).

Key Features:

  • Power Box RS UNI and Power Box RS TT-Lead combine to make power supply upgrade
  • Compatible with UNI 4-Way so you can still connect other RS electronics
  • Linear power supply upgrade for high-end turntables
  • Voltage regulator steps down voltage and reduces internal impedance
  • Improve turntable performance

Please Note: This upgrade is only compatible with Pro-Ject turntables that are supplied with 15V DC power supplies.


What is the difference between the standard and high-power TT Leads?

In terms of electrical design, both TT Leads are laid out the same. The only difference is that the "High Power" version has a vented box for the voltage regulator, and larger heat sinks. This allows it to better deal with the higher power demand required to run the heavier platter on the higher end turntables.

Which TT Lead do I need for my turntable?

Standard TT Lead version is for use with:

  • RPM 5 Carbon
  • The Classic
  • 2 Xperience SB
  • 2Xperience Acrylic
