How To Adjust Anti-Skate On Music Hall Turntables
Before adjusting the anti-skate on your Music Hall turntable, it’s important to ensure that the turntable is properly leveled, the cartridge is aligned, and the tracking force is correctly set.
Once you’ve taken care of these initial steps, you can begin adjusting the anti-skate force. Here’s how:
1. Set the anti-skate loop on the first notch.
2. Select a stereo LP record of your choice, preferably one that you’re very familiar with. Place it on the platter and switch the turntable to play.
3. Listen to the LP. When the anti-skating is too low, the left channel will dominate in terms of volume. Increase the anti-skating to the next notch and listen again. Repeat this step until you reach a point where both the right and left channels sound equally expressive, and the soundstage is wide open.
4. You will know that you have reached the correct anti-skating force when you have exceeded it. This will be manifested sonically by a sudden deterioration in sound quality. Then, adjust anti-skating to the previous notch.
It’s important to note that anti-skate should not be used for stereo imaging or any other purpose besides balancing tracking force and preventing distortion. If your record sounds best in the inner grooves, you may have too much anti-skate.
Music Hall turntables use a Pro-Ject tone arm system with three simple notches to adjust anti-skate. While some users may consider adding intermediate notches for fine-tuning, it’s generally not necessary with these turntables.
If you’re experiencing issues with your anti-skate weight rubbing against the support hoop, you can replace it with a fishing drop casting sinker weighing two grams. Use the formula VTF of your cartridge ÷ 0.63 = anti-skating weight in grams to determine the correct weight size for notch 3.
Understanding Anti-Skate Force
To understand anti-skate force, it’s important to first understand the forces at play when a turntable is in use. As the stylus tracks the record groove, it experiences a force of friction that pulls it forward along the groove. However, this force is not parallel to the tonearm or armtube. Instead, it can be resolved into two perpendicular components: one along the line running to the tonearm pivot (which causes no motion or side force on stylus), and one inward toward the spindle, perpendicular to the armtube.
If the stylus were not locked into the groove, the arm would move inward due to this inward component of the force vector. This is why anti-skate force is necessary: to exert a force on the tonearm to pull it outward and prevent excess pressure on one side of the record groove.
The anti-skate feature applies a small outward force to the tonearm, counteracting the tendency of the arm to move inward (skate) toward the center of the record as it approaches the end of the record. This helps maintain good channel balance, minimize distortion, and minimize stylus and record wear.
It’s important to note that while some turntables have an adjustable anti-skate control, others may not have this manual adjustment. However, this does not mean that the turntable does not have this feature; it may be handled internally or preset at a fixed value by the turntable’s manufacturer.
When adjusting anti-skate on a Music Hall turntable, it’s important to start with the loop on the first notch and adjust gradually until both channels sound equally expressive and the soundstage is wide open. It’s also important to note that anti-skate should not be used for stereo imaging or any other purpose besides balancing tracking force and preventing distortion.
Tools Needed For Adjusting Anti-Skate On Music Hall Turntables
Adjusting the anti-skate on your Music Hall turntable doesn’t require any specialized tools. However, you will need a few items to ensure that the process goes smoothly:
1. A stereo LP record of your choice: This will be used to test the anti-skate force at different notches.
2. A small screwdriver: You’ll use this to adjust the anti-skate weight on the tonearm.
3. A tracking force gauge: This will help you set the tracking force accurately before adjusting the anti-skate.
4. A level: Make sure your turntable is level before making any adjustments.
5. A clean workspace: Ensure that your workspace is clean and free from dust or debris that could damage your turntable or records.
By having these tools on hand, you’ll be able to adjust the anti-skate on your Music Hall turntable with ease and precision.
How To Measure Anti-Skate Force On Your Turntable
Measuring the anti-skate force on your turntable is crucial to achieving optimal sound quality. Here’s how to do it:
1. Start by playing the anti-skating test track on the AnalogMagik Test LP. Use the Anti-Skating function on the AnalogMagik software to measure the distortion figures between the left and right channels.
2. Repeat the measurements with increased or decreased anti-skating force until you find a balance where the distortion figures are as close together as possible.
3. Keep in mind that the amount of anti-skating force required will vary depending on the VTF, cartridge quality, and tonearm design. On good setups, you should aim for a distortion percentage difference of approximately 0.05% between channels, while the net number should be below 1% on good setups.
4. Some tonearm designs have inherent imbalances and will register numbers that are skewed towards one channel. In such cases, there’s nothing that can be done.
5. It’s important to note that antiskating affects azimuth, and an incorrect anti-skate setting can cause crosstalk readings to be skewed, making it impossible to achieve optimal numbers.
6. To achieve an optimal set of numbers, you may have to go back and forth between anti-skating and azimuth, as well as VTF and VTA. No setup parameter can be optimized in isolation.
7. Once you’ve adjusted the anti-skate force, listen to your record again to ensure that both channels sound equally expressive and that there’s no distortion or deterioration in sound quality.
By following these steps, you’ll be able to measure and adjust the anti-skate force on your turntable for optimal sound quality.
Testing Your Adjustments And Fine-Tuning For Optimal Sound Quality
Once you’ve adjusted the anti-skate on your Music Hall turntable, it’s important to test your adjustments and fine-tune for optimal sound quality. Here’s how:
1. Select a test record, such as the Hi-Fi News test record mentioned earlier, or any other test record that includes a bias setting track.
2. Set the anti-skate to zero and place the stylus on the test record’s bias setting track. Start playing the track and slowly increase the anti-skate force until you hear a clean and undistorted signal in both the left and right channels.
3. If you’re using a test record with other tracks, listen to them and make any necessary adjustments to the anti-skate force to achieve optimal sound quality.
4. Once you’ve fine-tuned the anti-skate force, listen to your favorite records and pay attention to the sound quality. If you notice any distortion or imbalance in the stereo image, make small adjustments to the anti-skate force until you achieve optimal sound quality.
Remember that adjusting anti-skate is a delicate process and requires patience and attention to detail. Take your time and don’t be afraid to make small adjustments until you achieve the best possible sound quality from your Music Hall turntable.
Tips For Maintaining Proper Anti-Skate On Your Music Hall Turntable
Once you have properly adjusted the anti-skate on your Music Hall turntable, it’s important to maintain it for optimal performance. Here are some tips to help you do just that:
1. Regularly clean your stylus to prevent buildup of debris that can affect tracking force and cause distortion.
2. Avoid using warped or damaged records, as these can cause uneven tracking force and lead to excessive wear on your stylus.
3. Keep your turntable level and on a stable surface to prevent any unwanted movement or vibration that can affect tracking force and anti-skate.
4. Don’t use excessive force when lowering the tonearm onto the record, as this can cause uneven tracking force and damage your stylus.
5. Check your anti-skate periodically to ensure that it is still properly adjusted. Over time, it may need to be readjusted due to changes in the cartridge or other factors.
By following these tips, you can maintain proper anti-skate on your Music Hall turntable and enjoy optimal sound quality from your vinyl collection.
