Tonearm effective mass is the mass of the tonearm, including the cartridge and headshell, that is seen by the record groove. It is a measure of how much force is required to move the tonearm, and it is an important factor in the tracking ability of the tonearm.
The effective mass of a tonearm is calculated by adding the mass of the tonearm, the cartridge, and the headshell. The mass of the cartridge and headshell is usually specified by the manufacturer. The mass of the tonearm can be measured using a scale.
The effective mass of a tonearm is measured in grams. A lower effective mass means that less force is required to move the tonearm, which can improve tracking ability. However, a lower effective mass can also make the tonearm more susceptible to vibrations.
The ideal effective mass for a tonearm depends on the type of cartridge that is being used. Some cartridges are more sensitive to tracking force than others. If you are using a sensitive cartridge, you will need to use a tonearm with a lower effective mass.
If you are not sure what effective mass tonearm you need, it is a good idea to consult with a qualified audio professional. They can help you choose the right effective mass tonearm for your cartridge and turntable.
Here are some of the factors that can affect the effective mass of a tonearm:
- The mass of the tonearm: The heavier the tonearm, the higher the effective mass.
- The mass of the cartridge: The heavier the cartridge, the higher the effective mass.
- The mass of the headshell: The heavier the headshell, the higher the effective mass.
It is important to note that the effective mass of a tonearm is just one factor that affects the tracking ability. Other factors, such as the compliance of the cartridge and the tracking force, will also have an impact on the tracking ability.
I hope this helps!
