If you’re a vinyl enthusiast, you may have come across the term “quartz” when researching turntables. But what does it actually mean?
Is it something you should pay attention to when selecting a turntable?
In this article, we’ll dive into the world of quartz and how it relates to turntables. We’ll also answer some common questions about using the quartz lock feature and pitch control on your turntable.
So sit back, relax, and let’s explore the fascinating world of turntable technology.
What Does Quartz Mean On Turntable
Quartz is a term used to describe a type of clock that is used in turntables to maintain a stable speed for platter rotation. This clock is known for its accuracy and stability, which makes it an ideal choice for turntables.
In a turntable, the quartz clock is used in conjunction with a phase-locked loop circuit. This circuit compares the motor rotation speed to a reference frequency generated by a quartz crystal oscillator. If the values drift, the circuit makes fine adjustments to maintain a stable speed.
The quartz lock feature on direct-drive turntables like the Audio-Technica AT-LP120 is there to ensure that the platter rotates at a constant speed, regardless of external factors. When you activate the quartz lock feature, the turntable’s pitch control feature is disabled, and the motor speed remains constant.
Understanding Quartz Technology In Turntables
Quartz technology is a type of clock that is used in turntables to maintain a stable speed for platter rotation. It is known for its accuracy and stability, which makes it an ideal choice for turntables. The quartz clock is used in conjunction with a phase-locked loop circuit, which compares the motor rotation speed to a reference frequency generated by a quartz crystal oscillator.
When the values drift, the circuit makes fine adjustments to maintain a stable speed. This is important because external factors such as worn belts or damaged flywheels can affect the speed of the platter. By using quartz technology, turntables can maintain a constant speed regardless of external factors.
The quartz lock feature on direct-drive turntables such as the Audio-Technica AT-LP120 is there to ensure that the platter rotates at a constant speed. When you activate the quartz lock feature, the turntable’s pitch control feature is disabled, and the motor speed remains constant. This is because the quartz lock feature locks the pitch at 0% difference, so that the record is being played back at exactly 33.3 or 45 RPM.
In contrast, belt-drive turntables are reliant on more moving parts, which inherently makes them more prone to speed changes. For example, if the belt is worn or the flywheel is damaged, the speed will certainly be affected. However, it is possible to improve the speed consistency of a belt-drive system by adding a speed regulator to the power supply.
The Importance Of Quartz In Turntable Selection
When selecting a turntable, the presence of quartz technology can be an important factor to consider. Turntables with quartz technology have a more accurate and stable rotation speed, which can significantly reduce wow and flutter. This means that the sound quality of your records will be better, and you can enjoy your music without any interruptions or distortion.
Moreover, quartz technology eliminates the need for manual speed adjustments, which can be a hassle for some users. This feature is particularly useful for DJs who need to maintain a consistent speed when playing music.
If you are looking for a turntable that delivers high-quality sound and reliability, then choosing one with quartz technology is a great option. It ensures that your records are played at the correct speed, and you can enjoy your music to the fullest.
Exploring Quartz Lock And Pitch Control Features
In addition to the quartz lock feature, some turntables also have a pitch control feature. This feature allows the user to adjust the speed of the platter rotation, which can be useful for DJing or correcting slightly off-center records.
However, when the quartz lock feature is activated, the pitch control feature is disabled. This is because the quartz lock ensures that the motor speed remains constant, so adjusting the pitch control would have no effect on the speed of the platter rotation.
If you do need to use the pitch control feature, you can disable the quartz lock and adjust the pitch slider until you reach your desired speed. However, it’s important to note that playing a record at an incorrect speed will not improve its quality or sound.
It’s also worth noting that the quartz lock feature cannot fix issues with off-center pressings. Its only job is to maintain a stable speed for platter rotation.
How Quartz Improves Turntable Performance
Quartz improves turntable performance by providing speed stability. This is reflected in the low wow and flutter figures for many quartz drive turntables, which are generally an order of magnitude or at least 5x better than most belt drive turntables. The quartz mechanism keeps the platter spinning at a constant speed, which makes it more accurate at maintaining speed than other types of mechanisms.
Direct-drive turntables, like the Technics SL-1200, represent one of the best bang-for-your-buck decks out there due to their quartz mechanism. They provide superior performance and accuracy compared to belt-drive turntables. While there are some great belt-drive units out there, the quartz mechanism is more reliable and accurate.
Many people still insist that belt-drive is the superior choice, but this is pure superstition. Any audible “cogging” due to the motor design in a direct-drive turntable would have to show up in the wow and flutter or noise specs. In fact, it is possible to improve the speed consistency of a belt-drive system by adding a speed regulator to the power supply.
Common Myths And Misconceptions About Quartz In Turntables
Despite the benefits of using quartz in turntables, there are several myths and misconceptions surrounding its use. One common myth is that quartz turntables are more fragile and prone to damage. However, quartz is a durable material with a Mohs hardness rating of 7, making it resistant to scratches and other types of damage.
Another common misconception is that quartz turntables are more expensive than other types of turntables. While it is true that some high-end turntables use quartz technology, there are also affordable options available for those on a budget.
Some people also believe that using a quartz turntable will result in a loss of sound quality. However, this is not necessarily true. The accuracy and stability of the quartz clock can actually improve the sound quality of your records by reducing wow and flutter.
Finally, there is a misconception that quartz turntables require more maintenance than other types of turntables. In reality, the maintenance requirements for a quartz turntable are similar to those of any other turntable. Regular cleaning and maintenance can help ensure that your turntable lasts for years to come.
In conclusion, while there may be some myths and misconceptions surrounding the use of quartz in turntables, this technology remains an excellent choice for those looking for accuracy, stability, and improved sound quality.
