A tonearm is a critical component of any turntable setup. It is tasked with one of the most crucial jobs in the chain of sound production—from the stylus touching the vinyl record to the audio signals reaching your ears. To deliver an optimum and accurate audio reproduction, proper adjustment of the tonearm and tracking force is necessary. This article seeks to demystify tonearm adjustment and tracking force to help you get the best sound quality out of your vinyl records.
Understanding the Tonearm
The tonearm, located on the right side of your turntable, houses your cartridge and stylus. Its role is to guide the stylus precisely over the grooves of the vinyl record to extract the audio information embedded within. Incorrect settings or adjustments can degrade sound quality or even damage your vinyl records or stylus over time.
Components of a Tonearm
To grasp tonearm adjustment, it’s important to understand its key elements. A typical tonearm is made up of a variety of components, each with its own function:
1. Counterweight: Balances the weight of the cartridge, adjusting the tracking force exerted on the record.
2. Anti-skating device: Maintains equilibrium in the stylus’s horizontal tracking.
3. Arm height adjustment: Alters the vertical position of the entire arm relative to the record.
4. Arm lift lever: Allows the tonearm to be lowered or raised from the record safely.
5. Headshell: Holds the cartridge and stylus and is usually removable for easy cartridge replacement or maintenance.
Setting the Tracking Force
The tracking force refers to the amount of downward pressure the stylus exerts on the vinyl record. It is measured in grams and set utilizing the counterweight found at the back of the tonearm.
To begin, remove any protective stylus cover, then reset the tonearm balance. This should be done carefully, so you don’t risk damaging the stylus. To do this floating the tonearm—adjusting the counterweight until the tonearm sits level with the platter. Once the tonearm floats freely, set the counterweight’s dial to zero without moving the weight itself.
After this, you’ll need to set your desired tracking force, which will usually be specified by the cartridge manufacturer. Rotate the counterweight (without moving the dial) clockwise to increase the tracking force and counterclockwise to decrease it.
Getting the Anti-skate Right
Anti-skate is a key adjustment that ensures the stylus tracks the record’s grooves evenly in both the left and right channels. Ideally, the amount of anti-skate dialled in should match the tracking force. For example, if your cartridge’s tracking force is 2 grams, then your anti-skate setting should also be at 2. It may require fine-tuning to find the perfect balance as anti-skate requirements can vary between different turntable and cartridge combinations.
Adjusting Tonearm Height (VTA)
Vertical Tracking Angle (VTA) refers to the angle at which the stylus hits the grooves of the record. This should be around 20 to 22 degrees, though it is subject to slight change due to variations in record pressing.
To adjust this, loosen the height adjustment collar situated near the base of the tonearm. From there, you can raise or lower the tonearm to meet the desired angle. Note that not all turntables come with the capability to adjust VTA.
Setting Overhang and Alignment
Overhang refers to the distance the stylus goes beyond the center of the spindle. The overhang and alignment of the cartridge are essential to minimize distortion and maintain consistent and correct sound reproduction.
To achieve this, use an alignment protractor—a special tool or template that shows exact measurement points. Ensure the stylus tip sits correctly on the points marked on the protractor, then carefully adjust the cartridge within the headshell until the alignment is correct.
In conclusion, fine-tuning your tonearm and adjusting the tracking force can significantly affect the audio quality you get from your vinyl records. It minimizes record and stylus wear, increases the life of your equipment, and most importantly, enhances your listening experience. Although these adjustments might seem complicated at first glance, with patience and practice, they become pretty straightforward.
Remember to always consult your turntable and cartridge instructions regarding specific adjustments and settings—each system may have unique features or requirements that need special attention. Enjoy the euphoria of well-played vinyl, knowing you’ve fine-tuned your turntable to its optimum performance.
