This foundation ensures that your calibration efforts will be effective.
Adjusting the Tracking Force
Understanding tracking force
Tracking force refers to the amount of pressure exerted by the stylus on the vinyl record during playback. It is crucial to set the tracking force within the manufacturer’s recommended range to prevent excessive grove wear or mistracking. Insufficient tracking force may result in skips and distortion, while excessive force can damage the record or the stylus.
Finding the recommended tracking force
Consult the user manual or the manufacturer’s website to determine the recommended tracking force for your specific cartridge. This information ensures that you can achieve the best possible sound quality while preventing unnecessary wear on your records.
Adjusting the tracking force
To adjust the tracking force, use a tracking force gauge. Place the gauge on the turntable platter and carefully lower the tonearm onto it. Observe the gauge reading and make the necessary adjustments using the counterweight located at the rear of the tonearm. Rotate the counterweight until the gauge reflects the recommended tracking force. Be sure to double-check the tracking force after making adjustments to ensure accuracy.
Setting the Antiskate
What is antiskate?
Antiskate, or anti-skating, is a mechanism designed to counterbalance the inward force exerted on the tonearm by the groove walls during playback. Setting the antiskate correctly helps maintain proper tracking and prevents the stylus from being pulled too forcefully towards the center or outer edge of the record.
Determining the recommended antiskate setting
The recommended antiskate setting for your turntable is typically provided by the cartridge manufacturer or can be found in the user manual. It is often expressed in the form of a number or range, corresponding to the tracking force used.
Adjusting the antiskate
To adjust the antiskate, use the antiskate adjustment tool provided with your turntable or tonearm. Consult the user manual for specific instructions on how to adjust the antiskate mechanism. Generally, you will adjust the antiskate to match the tracking force you have set, ensuring proper balance and allowing the stylus to track the grooves accurately.
Balancing the Tonearm
Why is balancing the tonearm important?
Balancing the tonearm is crucial for ensuring proper tracking and minimizing wear on both the stylus and the vinyl record. An unbalanced tonearm can cause mistracking, poor sound quality, and potential damage to your valuable vinyl collection. Balancing the tonearm properly allows for smooth and accurate playback.
Locating the tonearm balance point
The tonearm’s balance point is the position at which it is neither weighted down nor lifted up. To locate this point, gently elevate the tonearm and observe at which point it remains level. This indicates the balance point.
Adjusting the tonearm balance
Once you have identified the tonearm’s balance point, adjust the counterweight located at the rear of the tonearm. Rotate the counterweight until the tonearm is parallel to the turntable’s surface when positioned above the record. If the tonearm tilts up or down, make slight adjustments to the counterweight until balance is achieved.
Aligning the Cartridge
Why is cartridge alignment important?
Proper cartridge alignment ensures accurate tracking and minimizes distortion during playback. It ensures that the stylus is properly aligned within the groove walls, allowing it to reproduce the music as intended. Poor alignment can result in skips, mistracking, and subpar sound quality.
Types of cartridge alignment
There are various cartridge alignment methods, including Baerwald (also known as Löfgren A), Stevenson, and null point alignment. Each method has its own set of equations and alignment geometries. It is important to choose the alignment method recommended by the cartridge manufacturer or consult a professional if you are unsure.
Aligning the cartridge
To align the cartridge, use a protractor specifically designed for your chosen alignment method. Place the protractor on the turntable platter and carefully position the stylus according to the provided guidelines. Adjust the cartridge body using the provided screws or alignment mechanism until the stylus aligns perfectly with the designated points on the protractor. Take your time during this process to ensure accurate alignment.
Checking the Vertical Tracking Angle
Understanding vertical tracking angle
Vertical tracking angle (VTA) refers to the angle at which the stylus meets the record’s grooves. Proper VTA ensures optimal sound quality and minimal distortion during playback. If the VTA is not set correctly, it can result in imbalanced frequency response and compromised audio performance.
Checking the vertical tracking angle
To check the VTA, use a VTA gauge or a similar tool. Place the tool on the turntable plinth or tonearm base and adjust the tonearm height until the stylus is parallel to the tool’s surface. This ensures that the stylus is perpendicular to the record’s grooves and set at the correct VTA.
Making adjustments if necessary
If the VTA is not set correctly, adjust the tonearm height until the stylus aligns perfectly with the VTA gauge. Take into account any cartridge-specific recommendations or consult the cartridge and turntable manufacturer for guidance.
Eliminating Wow and Flutter
What is wow and flutter?
Wow and flutter refer to variations in the turntable’s rotational speed, resulting in pitch fluctuations during playback. These speed inconsistencies can produce audible wobbling or warbling effects, negatively impacting the listening experience.
Detecting wow and flutter
To detect wow and flutter, listen carefully to your turntable’s playback. Pay attention to any noticeable speed variations or pitch fluctuations. If you observe consistent speed variations or audible warbles, your turntable may be experiencing wow and flutter.
