When it comes to turntable cartridges, there are two main types: Moving Magnet (MM) and Moving Coil (MC). Each type has its own characteristics and requires specific settings for optimal performance. If you’re unsure about the type of cartridge installed on your turntable, this article will guide you through the process of determining whether your cartridge is MM or MC, enabling you to make informed decisions about setup, compatibility, and upgrades.
- Consult the Turntable Manual or Manufacturer: The easiest way to determine the cartridge type is by referring to the turntable’s manual or contacting the manufacturer. The manual or product description will usually specify the recommended cartridge type or provide information about the cartridge that comes pre-installed with the turntable. This is the most reliable and straightforward method to identify the cartridge type.
- Check the Cartridge Body Label: If the turntable manual or manufacturer’s information is not readily available, examine the cartridge itself. Many cartridges have a label or marking on the body that indicates whether it is an MM or MC cartridge. Look for abbreviations such as “MM” or “MC” on the cartridge body, often located near the connectors or on the top surface. However, not all cartridges may have clear markings, so additional methods may be necessary.
- Observe the Number of Pins: MM and MC cartridges differ in the number of pins used for connection. MM cartridges typically have two pins, while MC cartridges usually have four pins. Carefully examine the cartridge connectors on the tonearm or headshell. Count the number of pins present on the cartridge and compare it to the expected pin count for MM and MC cartridges.
- MM Cartridge: Two pins (one for each channel, usually left and right)
- MC Cartridge: Four pins (two for each channel, often labeled as “+” and “-“)
- Examine the Output Voltage Specifications: MM and MC cartridges also differ in their output voltage levels. MM cartridges generally have higher output voltages compared to MC cartridges. Check the technical specifications provided by the manufacturer or refer to the cartridge documentation to find the output voltage information. If the output voltage is relatively high (around 2-5 millivolts or higher), it is likely an MM cartridge. Conversely, if the output voltage is lower (usually below 1 millivolt), it is likely an MC cartridge.
- Seek Professional Assistance: If you have exhausted all the above methods and are still uncertain about the cartridge type, it may be beneficial to consult a knowledgeable audio professional or turntable specialist. They can help you identify the cartridge type accurately and provide recommendations for setup, compatibility, and potential upgrades based on your specific needs.
Conclusion: Determining whether your turntable cartridge is MM or MC is essential for proper setup, alignment, and compatibility. By referring to the turntable manual, checking the cartridge body labels, observing the number of pins, and examining the output voltage specifications, you can confidently identify the cartridge type. Remember that MM and MC cartridges have different characteristics and require specific settings to achieve optimal performance. If you are still unsure or seek further guidance, consulting the turntable manufacturer or seeking assistance from audio professionals can provide the necessary expertise to ensure the best possible audio experience with your turntable setup.
