Pitch Control vs Quartz Lock: Do You Need Both

What pitch control does

Pitch control is a feature that lets you adjust the turntable's playback speed, usually expressed as a percentage range above and below the standard 33⅓ and 45 RPM. It changes the rotation speed of the platter, which alters both the tempo and the pitch of the music. This is essential for DJs who need to beatmatch two tracks by matching their tempos, and for anyone who wants to fine-tune the speed for creative mixing.

Pitch control is typically found on direct-drive turntables designed for DJing, but it also appears on some belt-drive models. The adjustment is usually made with a slider or a series of buttons, and the range can vary. Some turntables offer a wide range, while others offer a narrower band for subtle corrections. If you never plan to mix or alter tempo, pitch control might be an unused feature, but it can still add flexibility.

For a deeper look at the mechanics of pitch adjustment, see our article on what turntable pitch control is.

What quartz lock does

Quartz lock is a speed stabilization technology that uses a quartz crystal oscillator to keep the platter speed precisely on target. The turntable continuously compares the actual platter speed with a reference generated by the crystal and corrects any drift. This eliminates wow and flutter caused by belt wear, voltage fluctuations, or other mechanical factors, ensuring the music plays at the intended pitch.

Quartz lock is especially valuable for listeners who want accurate pitch and timing. It is common on higher-end turntables, especially direct-drive models aimed at audiophiles. Because it locks the speed, you get consistent playback from the start of a record to the end, without the gradual slowdown that can affect less stable designs.

How they work together

On many turntables, pitch control and quartz lock are not mutually exclusive. You can first use the pitch slider to set a desired tempo, then engage quartz lock to hold that speed precisely. This combination gives you the flexibility to adjust speed for mixing while ensuring that the speed does not drift once set. It is a powerful feature set for DJs who need both control and stability.

In practice, the two features work in tandem. Without quartz lock, a pitch-controlled turntable might drift over time, causing the beat to gradually fall out of sync. With quartz lock engaged after setting the pitch, the speed remains rock steady, making beatmatching more reliable. For home listeners, quartz lock alone is often enough, but having pitch control as an option does not hurt.

The distinction between the two is clarified in our article on quartz lock speed control.

Who needs pitch control

Pitch control is a must for DJs who mix records. It allows you to match the tempo of two tracks so they play in sync, a technique called beatmatching. Without pitch control, you would have no way to adjust the speed of a record to match another. Even for casual mixing, a small pitch range can be useful for subtle tempo corrections.

Scratching and turntablism also rely on pitch control. DJs often adjust pitch to change the character of a sound or to align with a backing track. If you plan to perform or practice DJing, pitch control is non-negotiable. Direct-drive turntables with pitch control are the standard for this use, as they also offer the high torque needed for quick starts and stops.

Who needs quartz lock

Quartz lock is for anyone who values accurate pitch and worry-free playback. If you listen to records for pleasure, you want the music to sound exactly as the artist intended. A stable platter speed ensures that the pitch never wavers, which is especially important for vocals and acoustic instruments. Quartz lock gives you that peace of mind.

It also reduces the impact of external factors like voltage fluctuations, which can cause a motor to slow down or speed up. On a quartz-locked turntable, the speed is constantly corrected, so you can play records without constantly checking if the music sounds right. For high-end systems, quartz lock is a hallmark of engineering quality.

If you are building a home listening setup, you might not need pitch control at all. Focus on speed accuracy and other specs. Our article on turntable speed accuracy and wow and flutter explains why this matters. You might also want to compare belt drive vs direct drive to see which suits your needs.

Deciding what to buy

The choice boils down to your intended use. DJs and turntablists need pitch control, and often quartz lock as a bonus for stability. Home listeners can be perfectly happy with a turntable that has quartz lock but no pitch control. Many entry-level and mid-range turntables offer neither, relying on a well-regulated motor to maintain speed. If you want to guarantee accuracy, look for quartz lock.

You can also find turntables that give you both. These are often direct-drive models marketed for DJs, but they work just as well for home listening. The added complexity of pitch control does not diminish sound quality as long as the turntable is well built. In fact, having both gives you maximum flexibility for the future, should you ever decide to try mixing.

What to pick for your use

Questions

Can you use pitch control and quartz lock at the same time?

Yes, many turntables allow you to set the pitch first and then engage quartz lock to hold that speed. This combines the flexibility of adjustment with the stability of locking.

Does quartz lock affect sound quality?

Quartz lock improves speed consistency, which helps maintain accurate pitch. It does not alter the sound directly, but a stable speed prevents pitch instability that can affect tonal accuracy.

Do all turntables have pitch control?

No, pitch control is most common on DJ-oriented direct-drive turntables. Many home turntables omit it to keep the design simple and reduce cost.

Is quartz lock worth having?

If you are sensitive to pitch accuracy and want worry-free playback, yes. Quartz lock ensures the platter speed stays on target, which is especially valuable for critical listening.

Can I add pitch control to a turntable that does not have it?

No, pitch control is a hardware feature built into the motor control circuit. You cannot retrofit it. If you need pitch control, choose a turntable that includes it.

Do belt-drive turntables ever have quartz lock?

Yes, some belt-drive turntables incorporate quartz lock to stabilize speed. While less common than on direct-drive models, it is a feature found on higher-end belt drives.
