How Phono Cartridges Work
A phono cartridge is an essential component of a turntable, responsible for converting the vibrations from the vinyl record grooves into electrical signals that can be amplified and played through speakers. It consists of a stylus (needle) that tracks the grooves, a cantilever that supports the stylus, and a cartridge body that houses the magnets or coils.
There are two main types of phono cartridges: Moving Magnet (MM) and Moving Coil (MC). While both types work on the same principle of generating an electrical signal through magnetic induction, they differ in their design and operation.
MM cartridges are the more common and affordable option. They have a fixed magnet that moves along with the stylus, generating a voltage as it passes over the coils. This voltage is then sent through the turntable’s tonearm and RCA cables to the amplifier. MM cartridges typically have a high output level, making them compatible with most standard phono preamps.
On the other hand, MC cartridges have a stationary magnet and a coil that moves with the stylus. The stylus is attached to a cantilever, which is suspended within the coil’s magnetic field. As the stylus moves, it generates a small current in the coil, which is sent to the amplifier. MC cartridges usually offer better sound quality and tracking ability, but they require a phono preamp with high gain and impedance.
Regardless of the type, the performance of a phono cartridge is influenced by various factors, including the stylus shape (conical, elliptical, etc.), tracking force, compliance (ability to follow the record groove contours), and channel separation. Finding the right balance between these factors is crucial for optimal sound reproduction and longevity of both the cartridge and the vinyl records.
In the next sections, we will compare the sound quality, tracking ability, noise levels, output level, price range, compatibility, and overall performance of moving magnet and moving coil phono cartridges to help you make an informed decision when choosing the right cartridge for your turntable setup.
