But what sets an MM turntable apart from other types? To answer that question, let’s delve into the components and inner workings of an MM turntable.

 

Definition of an MM Turntable

At its core, an MM turntable is a device used to play vinyl records. It consists of various components that work together to produce high-quality sound. The distinguishing feature of an MM turntable is the type of cartridge it uses – the Moving Magnet cartridge.

The Moving Magnet cartridge is an integral part of an MM turntable. It is responsible for translating the physical grooves on a vinyl record into an electrical signal that can be amplified and heard through speakers. This cartridge is called a “Moving Magnet” because it has a magnet attached to the cantilever or stylus, which moves with the vibrations of the record. The movement of the magnet generates a small electrical current, which is then amplified to reproduce the sound recorded on the vinyl.

An MM turntable typically has a tonearm that holds the cartridge and stylus in place. The tonearm is carefully calibrated to ensure precise tracking and minimize any distortion or skipping. It also features a counterweight and anti-skate mechanism to maintain the correct tracking force and reduce wear on the record.

In addition to the tonearm and cartridge, an MM turntable includes a platter, which spins the vinyl record at a constant speed. The platter is usually made of aluminum or acrylic and is designed to provide stable rotation for accurate playback. Some high-end MM turntables may also feature a belt drive system, where the platter is driven by a belt connected to a motor, resulting in reduced vibrations and better sound quality.

To control the speed of the platter, an MM turntable typically has a motor and a speed control mechanism. This allows you to switch between different playback speeds, such as 33 1/3, 45, and sometimes 78 revolutions per minute (RPM), depending on the record being played.

To connect the turntable to an audio system or speakers, most MM turntables have a set of RCA output jacks. These jacks allow you to send the amplified signal to a receiver, preamp, or powered speakers for playback.

Now that we have a clear understanding of what an MM turntable is and its basic components, let’s dive deeper into how it works and explore the benefits of using one.

 

Components of an MM Turntable

An MM turntable consists of several key components that work in harmony to deliver high-quality sound reproduction. Understanding these components can help you appreciate the intricate design and engineering behind a well-crafted MM turntable. Let’s take a closer look at each of these components:

  1. Tonearm: The tonearm is responsible for holding the cartridge and stylus. It is a crucial component that ensures the proper tracking and smooth movement of the stylus across the grooves of the record. The tonearm’s design and construction play a significant role in minimizing vibrations and maintaining accurate tracking force.
  2. Cartridge: The cartridge is arguably the most vital component of an MM turntable. It houses the stylus, cantilever, and magnets. The stylus, often diamond-tipped, tracks the record grooves and translates the physical movements into electrical signals. The cantilever transfers these movements to the magnets, generating electrical currents that are then sent to the phono stage for amplification.
  3. Platter: The platter is the circular platform on which the vinyl record sits. It spins at a constant speed, allowing the stylus to track the record grooves accurately. The platter’s material and weight distribution impact the turntable’s overall stability, vibration control, and rotational accuracy. High-end MM turntables often feature heavy platters made of materials like aluminum, acrylic, or glass to enhance performance.
  4. Motor: The motor is the driving force behind the platter’s rotation. It maintains a consistent speed so that the stylus can accurately read the record’s grooves. MM turntables typically adopt either a belt-drive or direct-drive system. In a belt-drive system, the motor spins a belt that, in turn, rotates the platter, resulting in lower motor noise and vibrations. Direct-drive systems, on the other hand, have the motor directly attached to the platter for better speed stability and quick start/stop functionality.
  5. Speed Control: MM turntables offer different playback speeds, commonly 33 1/3, 45, and sometimes 78 RPM. The speed control mechanism allows you to switch between these speeds, ensuring optimal playback for the specific record you are listening to. Some turntables offer manual speed adjustment, while others have electronic controls for convenient switching.
  6. Isolation Feet: Isolation feet are used to reduce vibrations and isolate the turntable from external disturbances. They provide stability and minimize the transmission of vibrations from the surface it rests on, helping to maintain accurate tracking and sound quality.
  7. Phono Stage: The phono stage, also known as a phono preamp, is an essential component for MM turntables. It amplifies the small electrical signals produced by the cartridge and prepares them for output to an audio system or speakers. Some turntables have a built-in phono stage, while others require an external phono preamp for proper signal amplification.

By understanding the various components of an MM turntable, you can make informed decisions when choosing the right turntable for your needs. Each component plays a crucial role in delivering accurate tracking, low distortion, and exceptional sound quality.

 

How an MM Turntable Works

An MM turntable works by converting the physical grooves on a vinyl record into an electrical signal that can be amplified and played through speakers. The process involves the precise movement of components and the meticulous tracking of the stylus along the record’s grooves. Let’s explore the step-by-step process of how an MM turntable works:

  1. Placing the vinyl record: Start by placing the vinyl record onto the turntable’s platter. Ensure that the record is centered and sits flat on the platter, ensuring optimal tracking and minimizing unwanted vibrations.
  2. Lowering the tonearm: Gently lower the tonearm, allowing the stylus to make contact with the record’s surface. The tonearm’s mechanism should provide a smooth and controlled descent to avoid damaging the stylus or the record.
  3. Stylus tracking the grooves: As the record begins to rotate, the stylus tracks along the record’s grooves. The diamond-tipped stylus precisely follows the contours of the grooves, picking up the vibrations encoded in the record’s surface.
  4. Generating electrical signal: The stylus’s movements cause the cantilever to flex, which in turn moves the magnets attached to it. This movement generates a small electrical current in the coil surrounding the magnets.
  5. Amplification: The small electrical signal produced by the cartridge needs to be amplified before it can be heard through the speakers. The MM turntable’s phono stage or preamp boosts the signal to line level, making it compatible with other audio equipment.
  6. Connectivity: The amplified signal is then sent to an audio system or speakers via the MM turntable’s output jacks. These output jacks are usually RCA connectors that allow for easy connection to a receiver, preamp, or powered speakers.
  7. Playback: With the amplified signal now connected to the audio system, the sound from the vinyl record is played back through the speakers, filling the room with the warm and distinct sound of analog music.
  8. Tracking force and anti-skate: Throughout the playback process, it’s important to maintain precise tracking force and anti-skate settings. This helps ensure that the stylus remains in contact with the record’s grooves without pressing too heavily or skipping, resulting in the best possible sound quality.

MM turntables rely on precision engineering and careful calibration to reproduce the best possible sound from vinyl records. The combination of the stylus, cartridge, tonearm, platter, and other components work together to deliver a truly immersive and enjoyable listening experience.
