Understanding the type of cartridge on your turntable is essential for optimizing your vinyl playback setup. Two common types of cartridges are moving coil (MC) and moving magnet (MM). Whether you’ve inherited a turntable, purchased one secondhand, or simply forgotten the specifics of your setup, this article will help you identify whether you have a moving coil or moving magnet cartridge.
Differentiating Between MC and MM Cartridges
1. Check the Cartridge Body:
Moving Coil Cartridge (MC): MC cartridges tend to have a more compact design with a smaller body. The wires connecting to the cartridge pins are usually thin and delicate.
Moving Magnet Cartridge (MM): MM cartridges often have a larger and more substantial body. The wires leading to the cartridge pins are usually thicker and more robust.
2. Examine the Stylus Assembly:
Moving Coil Cartridge (MC): MC cartridges typically have a smaller stylus assembly with a fine and delicate stylus tip. The stylus is often housed in a small and precise cantilever.
Moving Magnet Cartridge (MM): MM cartridges have a larger stylus assembly with a stylus tip that may appear more substantial. The cantilever might be larger and less delicate compared to MC cartridges.
3. Look for Model Markings:
Moving Coil Cartridge (MC): MC cartridges often have model names or numbers that include the term “MC” or “Moving Coil.”
Moving Magnet Cartridge (MM): MM cartridges may have model names or numbers that include the term “MM” or “Moving Magnet.”
4. Check Manufacturer Specifications:
Refer to the documentation or specifications that came with your turntable or cartridge. If you no longer have the documentation, you can often find manufacturer specifications and details online using the model name or number.
5. Test with a Magnet:
Moving Coil Cartridge (MC): MC cartridges are not influenced by magnets. If a magnet is placed near the cartridge, there should be little to no effect on its performance.
Moving Magnet Cartridge (MM): MM cartridges are sensitive to magnets. If a magnet is brought close to the cartridge, you might notice a change in sound or even distortion.
6. Seek Professional Assistance:
If you’re still unsure about the type of cartridge you have, consider seeking help from a knowledgeable audio specialist, turntable technician, or retailer. They can provide expert guidance based on visual inspection and tests.
Identifying whether you have a moving coil or moving magnet cartridge is crucial for optimizing your turntable setup and choosing compatible equipment. By examining the cartridge body, stylus assembly, model markings, and using basic tests, you can confidently determine the type of cartridge you have. This knowledge will guide your decisions when selecting phono preamps, replacement styli, and other components to enhance your vinyl listening experience.
