Are you unsure if your turntable is equipped with a moving magnet (MM) or moving coil (MC) cartridge?
Don’t worry, you’re not alone.
It can be difficult to determine the type of cartridge installed on your turntable just by looking at it. However, understanding the differences between MM and MC cartridges can greatly impact the sound quality of your vinyl collection.
In this article, we’ll explore the key differences between MM and MC cartridges, how to identify which type you have, and what to consider when choosing a replacement cartridge.
So, let’s dive in and discover if your turntable is MM or MC.
Is My Turntable MM Or MC
The easiest way to determine if your turntable is equipped with an MM or MC cartridge is to look at the stylus itself. MM cartridges have a relatively sharp diamond stylus tip, which measures approximately 0.001 of an inch wide. On the other hand, MC cartridges have a longer and narrower diamond stylus tip, measuring 0.001-0.004 inches wide.
Another way to determine the type of cartridge is by reading the text printed on the front of the cartridge. For example, you may find a round sticker on your cartridge that reads MM = Moving Magnet or MC = Moving Coil (MM-MC).
It’s important to note that if your turntable has a replaceable stylus, it’s most likely an MM cartridge. However, if it has a fixed stylus, it’s an MC cartridge.
The main difference between MM and MC cartridges is in how they generate a signal. An MM cartridge uses a magnet that moves in response to the stylus tracking the record grooves, while an MC cartridge uses coils of wire that move in response to the stylus tracking the grooves.
MC cartridges are preferred by audiophiles and engineers due to their lighter and smoother motion. However, they are typically more expensive than MM cartridges due to the finer wires needed to create a moving coil.
When choosing a replacement cartridge, it’s important to consider factors such as the condition and material of the stylus, the cantilever’s material, and the positioning of the internal parts of your cartridge.
In addition, make sure to choose a cartridge that is compatible with your turntable’s input. Many low-end turntables come equipped with an MM cartridge, while mid-market turntables may have both MM and MC inputs.
What Are MM And MC Cartridges?
MM and MC cartridges are tiny electromagnetic generators that convert the mechanical movement created by their stylus riding in a record’s groove into an electrical signal that can be amplified and processed by a sound system for us to enjoy.
MM cartridges have a magnet that moves in response to the stylus tracking the record grooves, while MC cartridges have coils of wire that move in response to the stylus tracking the grooves.
MM cartridges have a relatively sharp diamond stylus tip, which measures approximately 0.001 of an inch wide. MC cartridges, on the other hand, have a longer and narrower diamond stylus tip, measuring 0.001-0.004 inches wide.
MC cartridges are more delicate compared to MM cartridges and typically do not have a user-replaceable stylus. They also require more delicate electronics than MM cartridges to work without issues due to their lower signal level, which makes them more sensitive to noise.
MM cartridges are more user-friendly and budget-friendly than MC cartridges. When the stylus is worn on an MM cartridge, it can usually be replaced without also replacing the whole cartridge. However, on an MC cartridge, you either have to buy a new cartridge or pay a cartridge specialist good money to replace the stylus for you.
How To Identify If Your Turntable Has An MM Or MC Cartridge
To identify if your turntable has an MM or MC cartridge, the easiest way is to look at the stylus. MM cartridges have a diamond stylus tip that is relatively sharp and measures approximately 0.001 of an inch wide. Meanwhile, MC cartridges have a longer and narrower diamond stylus tip that measures 0.001-0.004 inches wide.
Another way to determine the type of cartridge is by reading the text printed on the front of the cartridge. You can find a round sticker on your cartridge that reads MM = Moving Magnet or MC = Moving Coil (MM-MC).
If your turntable has a replaceable stylus, it’s most likely an MM cartridge. However, if it has a fixed stylus, it’s an MC cartridge.
It’s important to note that you cannot tell a cartridge by its shape alone. The most common type of cartridge is the MM, with a replaceable stylus. To use a low output moving coil cartridge, you need more specialized equipment. However, a high output moving coil will work with a standard moving magnet input.
When choosing a replacement cartridge, make sure to consider factors such as the condition and material of the stylus, the cantilever’s material, and the positioning of the internal parts of your cartridge.
In addition, if you’re unsure which type of cartridge your turntable has, take a close look at it and take note of the type description printed on it. From there, you can simply type the description into Google and look at the top search results to determine if it’s an MM or MC cartridge.
Differences Between MM And MC Cartridges
There are several key differences between MM and MC cartridges. One of the most significant differences is in how they generate a signal. MM cartridges use a magnet that moves in response to the stylus tracking the record grooves, while MC cartridges use coils of wire that move in response to the stylus tracking the grooves.
Another difference is in their weight and size. MM cartridges tend to be smaller and lighter than MC cartridges, typically weighing around 6-9 grams. In contrast, MC cartridges typically weigh between 9 and 18 grams.
Additionally, MC cartridges require a step-up device such as a transformer or head-amp to work with a standard preamplifier, while MM cartridges do not.
One advantage of MM cartridges is that they are more user-friendly than MC cartridges. They are less sensitive to noise and do not require as delicate electronics as MC cartridges to work without issues. Additionally, when the stylus on an MM cartridge is worn out, it can usually be replaced without having to replace the entire cartridge. In contrast, with an MC cartridge, you either have to buy a new cartridge or pay a cartridge specialist to replace the stylus for you.
On the other hand, MC cartridges are generally preferred by audiophiles and engineers due to their ability to produce a wider array of frequencies and provide a more responsive medium. They are capable of reaching audiophile heights and can provide higher quality sound than MM cartridges.
Ultimately, when choosing between an MM or MC cartridge, it’s important to consider factors such as your budget, your turntable’s input compatibility, and your personal preferences for sound quality. Both types of cartridges can provide great performance and are offered in a range of prices, shapes, sizes, and levels of quality.
Advantages And Disadvantages Of MM And MC Cartridges
MM and MC cartridges both have their own set of advantages and disadvantages.
MM cartridges are generally more affordable and have a replaceable stylus, making it easier to change the needle or upgrade to a different stylus type. They also have a medium to high output level, which means they require less gain in the phono stage to amplify the sound. Additionally, MM cartridges are typically more compatible with a wider range of household stereo equipment, making them a simpler choice for installation.
On the other hand, MC cartridges are preferred by audiophiles due to their ability to produce a smoother and more detailed sound. They have a lighter and smoother motion, resulting in improved high-frequency transients and a more detailed reproduction of the original waveform. However, they are typically more expensive than MM cartridges due to the finer wires needed to create a moving coil. MC cartridges also require a dedicated preamp that comes at an additional cost.
Another disadvantage of MC cartridges is that they often have a fixed stylus, which can make them more prone to parasitic vibrations caused by the stylus carrier. In contrast, some MM cartridges come with a firmly fixed or screwed-on stylus that eliminates this issue.
Ultimately, the choice between MM and MC cartridges depends on personal preference and budget. If you’re on a budget and want an easily replaceable stylus with wider compatibility, an MM cartridge may be the better option. However, if you’re willing to invest in a higher-quality sound and have a dedicated preamp, an MC cartridge may be worth considering. Regardless of your choice, make sure to choose a cartridge that is compatible with your turntable’s input for optimal performance.
Choosing The Right Replacement Cartridge For Your Turntable
When it comes to choosing the right replacement cartridge for your turntable, there are a few things to consider. First and foremost, you need to determine whether your turntable is equipped with an MM or MC cartridge. As mentioned earlier, MM cartridges are more common and tend to be less expensive than MC cartridges. However, if you’re looking for the best possible sound quality, an MC cartridge may be the way to go.
Once you’ve determined the type of cartridge you need, it’s important to consider the quality of the stylus. Look for a stylus that is made of high-quality materials and has a shape that is appropriate for your turntable’s tonearm. The shape of the stylus affects how it makes contact with the record groove, so it’s important to choose a stylus that is designed to track your records accurately.
You should also consider the cantilever’s material when choosing a replacement cartridge. The cantilever is responsible for transferring vibrational energy from the stylus tip to the magnet or other generating element, so it’s important that it be as stiff and light as possible. Aluminum alloy is the most common material used in cantilevers, but carbon, boron, and certain copper alloys are also used.
Another factor to consider when choosing a replacement cartridge is trackability. This spec describes how well the stylus can track a modulated record groove. Trackability is influenced by many factors, including stylus shape, cartridge alignment, and tonearm compatibility. Look for a cartridge with a high trackability spec for best results.
Finally, make sure that the replacement cartridge you choose is compatible with your turntable’s input. Most cartridges are either standard mount or P-mount, so make sure you choose a cartridge that is compatible with your turntable’s tonearm.
