Replacement counterweight number 30 (weight 71 g) for Pro-Ject RPM10, Xtension 10, X1 and 1-Xpression Carbon turntables
Replacement counterweight number 30 (1945875030) for Pro-Ject RPM 10, Xtension 10, X1 and 1-Xpression Carbon turntables (see configurator below).
Weight of counterweight 71 g.
For increased vibration resistance and better damping, the weight is filled with Sorbotan® on the back side.
The purpose of the counterweight is to set the optimum contact force for the turntable.The precisely adjusted downforce guarantees the best possible groove tracking and perfect reading of the recorded information. Correctly adjusted vertical contact force (VTF) on the stylus is a prerequisite for the best listening experience
Finding the most suitable counterweight depends on the type of turntable, the type of arm and the weight of the fitted cartridge.
CONFIGURATOR
Before placing an order, we recommend that you check in the turntable and turntable database on the configurator that the selected counterweight matches your turntable and turntable configuration.
In cases where you do not find a suitable counterweight for your turntable in the configurator, you can try searching for a suitable type in the detailed configuration table which you can find in the download section for each counterweight model.
THE PROCEDURE FOR SETTING THE PRELOAD (VTF)
The correct pressure range is individual to each turntable and the recommended values for your turntable can be found in the turntable's user manual. The most typical downforce values for current transmissions range from 1.3 to 2 grams. (It used to be much more). Sometimes the pressure values may be quoted in units of mN (milinewton). The conversion is simple 1 g = 10 mN. The pressure is adjusted by means of a pivoting counterweight installed at the end of the arm.
By rotating the counterweight, first try to reach a position where the arm remains in equilibrium (floating) and the tip floats freely a few millimeters on the LP plate surface. If the arm is gently deflected up or down, the arm will spontaneously return to its original position.Then hold the metal part of the counterweight in the set position to prevent it from rotating anymore, and on the pivoting set the value 0 (zero) with the other hand on the pivoting scale - the default position - by aligning zero with the adjustment mark on the arm tube. Then, by rotating the whole counterweight and the scale, the desired pressure values can be set.
Alternatively, it is possible to use additional aids such as mechanical (usually included in theor digital scales (must be purchased) specifically designed for measuring the pressure of the turntables. The adjustment is of course most accurate when using a digital scale, e.g. Pro-Ject MEASURE IT E or MEASURE IT S2 (accurate to 3 decimal places).
A video tutorial for setting the pressure can be found HERE.
