From connecting the cartridge to your turntable, to aligning it for perfect playback, we’ve got you covered.
So sit back, relax, and let’s dive into the world of phono cartridges.
How To Set Up A Phono Cartridge
Step 1: Mounting the Cartridge
The first step in setting up a phono cartridge is mounting it onto the headshell of your turntable. Most turntables and headshells accept cartridges with a 0.5 inch spacing between the mounting holes. Use the screws and nuts provided with the cartridge to secure it into place on the headshell assembly.
Step 2: Connecting the Cartridge
Once you have mounted the cartridge onto the headshell, it’s time to connect it to your turntable. Use the following color codes to ensure correct connection:
– Red = ‘+ Right’
– Green = ‘- Right’
– White = ‘+ Left’
– Blue = ‘- Left’
Step 3: Setting the Azimuth
To ensure optimal sound quality, it’s important to set the azimuth of your cartridge. This refers to the angle between the plane of the turntable and the vertical axis of the phono cartridge. The stylus must be perpendicular to the record to prevent any imbalance between the right and left channels of the groove. Use a small screw located on the tonearm hinge to adjust the azimuth. Note that this screw may be hidden by the external ring of the hinge or directly in the headshell, depending on your turntable model.
Step 4: Setting the Alignment
Using an alignment template, ensure that your cartridge is perfectly aligned on the groove’s tangent. Position this template on the platter of your turntable and place your cartridge on the mark. Check if it is aligned horizontally and vertically, corresponding to the overhang of a cartridge. Once aligned, ensure that you apply the recommended tracking force correctly.
Step 5: Checking for Damage
Phono cartridges are fragile, so it’s important to handle them with care. Check that your stylus cover is still properly mounted before use. If you have a moving magnet design, it may be possible to get a replacement stylus assembly if necessary. However, if you damage a moving coil cartridge, you’ll likely need to purchase a new one or get it repaired at great cost.
Understanding Phono Cartridges
Phono cartridges are the heart of your turntable’s sound system. They convert the mechanical vibrations of the stylus into electrical signals that are amplified and transformed into music. There are two main types of phono cartridges: moving magnet (MM) and moving coil (MC).
Moving magnet cartridges have a magnet attached to the end of the cantilever, which moves in a fixed coil to create an electrical signal. They are generally more affordable and easier to use than moving coil cartridges, but they can lack some of the detail and accuracy of their more expensive counterparts.
Moving coil cartridges are more complex and expensive, but they offer superior sound quality. They have a tiny coil attached to the cantilever, which moves within a fixed magnet to create an electrical signal. This design allows for greater accuracy and detail, but it also requires a more powerful preamp or amplifier to properly drive the signal.
When choosing a phono cartridge, it’s important to consider your budget, as well as the quality of your turntable and sound system. It’s also important to choose a cartridge with a stylus that matches the type of records you will be playing (e.g. 78 RPM vs. 33 RPM).
In addition, it’s important to properly care for your phono cartridge to ensure optimal sound quality and longevity. This includes regularly cleaning the stylus and keeping the cartridge protected when not in use.
By understanding the different types of phono cartridges and how to properly care for them, you can ensure that your turntable produces high-quality sound for years to come.
Choosing The Right Cartridge For Your Turntable
When it comes to choosing the right cartridge for your turntable, there are a few key factors to consider. The first is the stylus shape. The narrower the contact radius of the stylus, the better it will be able to track modulations in the groove. Elliptical shaped styli have a smaller contact radius than conical styli, allowing them to trace grooves more accurately and extract more musical information, especially high frequencies.
Another important factor is the cantilever. The material, size, and construction of the cantilever affect how well a cartridge can reproduce a range of audio frequencies. The most common material used in cantilevers is aluminum alloy, although carbon, boron, and certain copper alloys are often used.
Trackability is also an important spec to consider. This refers to how well the stylus can track a modulated record groove. Trackability is influenced by many factors, including stylus shape, cartridge alignment, and tonearm compatibility. The higher the trackability spec, listed in micrometers (μm), the better.
The generator type is another consideration. The two main types are moving magnet (MM) and moving coil (MC). MM cartridges are most common, while MC cartridges tend to be lower output and require a preamp with a special MC setting. MC cartridges are generally more expensive.
Finally, it’s important to consider mount type. Most cartridges are standard mount and secured to the tonearm by 2 vertical screws spaced 1/2″ apart and feature four small posts for connecting the tonearm leads. P-mounts have four slender pins that plug directly into tonearms specifically made for use with P-mount cartridges.
When choosing a cartridge for your turntable, consider your home system, budget range, and what kind of listening experience you consider ideal. Research different brands and models to find one that meets your specific needs and preferences.
Tools You’ll Need For Cartridge Setup
To set up a phono cartridge, you’ll need a few tools to ensure that your cartridge is mounted and calibrated correctly. Here are the tools you’ll need:
1. Screwdriver: You’ll need a flat-head screwdriver to mount the cartridge onto the headshell assembly. Make sure it’s the right size for the screws provided with your cartridge.
2. Long-nose pliers: These pliers come in handy when disconnecting the lead-out wires from the cartridge. They allow you to gently grip the connector at the cartridge end and pull it out without damaging the wires.
3. Tracking weight gauge: This tool is essential for setting the tracking force of your cartridge. It measures the downward force that your stylus exerts on the record and ensures that it’s within the recommended range for your cartridge.
4. Cartridge alignment tool: An alignment tool helps you position your cartridge precisely on the groove’s tangent. It ensures that your stylus tracks accurately and minimizes distortion.
5. Azimuth adjustment tool: This tool allows you to adjust the azimuth of your cartridge, ensuring that it’s perpendicular to the record groove. A small screw located on the tonearm hinge is used to make this adjustment.
6. Test record (optional): While not necessary, some audiophiles use a test record to fine-tune their cartridge setup. Test records can help you dial in azimuth, tracking force, and other tonearm adjustments, but they’re not essential if you trust your ears.
By using these tools and following the steps outlined above, you can set up your phono cartridge for optimal sound quality and maximum musical enjoyment.
Connecting Your Cartridge To Your Turntable
After mounting your cartridge onto the headshell and connecting the wires, it’s important to ensure that the cartridge is properly connected to your turntable. To do this, you’ll need to follow the color codes provided by your cartridge manufacturer. Typically, red is for the right channel positive, green is for the right channel negative, white is for the left channel positive, and blue is for the left channel negative.
To connect your cartridge to your turntable, you’ll need to use a pair of long-nose pliers to gently connect each wire to its corresponding pin on the back of the cartridge. Be careful not to push too hard or damage any of the connectors. Once all four wires are connected, you can remove the stylus guard and proceed to set up your tonearm.
To avoid damaging your cartridge during this process, it’s best to remove the counterweight and secure your tonearm in its resting place with a cable tie. This will prevent any accidental movements that could cause damage.
Once you have connected your cartridge to your turntable, it’s important to check for any signs of damage or misalignment. If you notice any issues, it’s best to address them before playing any records. Remember, taking care of your phono cartridge will ensure that you get the best possible sound quality from your vinyl collection.
Balancing Your Tonearm
The final step in setting up your phono cartridge is balancing your tonearm. This is crucial for optimal sound quality and preventing damage to your stylus and records.
To begin, power off your turntable and ensure that the counterweight is properly installed on the end of the tonearm with the numbers facing the front of the turntable. Make sure that the anti-skate is set to 0.
Next, use the cueing lever to lock the tonearm in the rest position on the armrest. Gently remove the protective cover from the stylus by sliding it straight forward off the front of the cartridge. Be very careful not to damage the stylus.
Gently hold the headshell to keep the tonearm stable while releasing the tonearm locking clamp. The tonearm will now swing freely since it’s unbalanced, so be sure to hold onto the headshell to prevent it from crashing into the turntable platter.
Keep the cueing lever in the down position while holding the headshell above the rest position. Carefully turn the counterweight on the rear of the tonearm until the tonearm is horizontally balanced. This means that the headshell won’t be moving up or down but will naturally float above the rest position.
Once you’ve found this balance spot, set the counterweight to zero. Now, you’ll want to set the proper tracking force for your phono cartridge. Turn your entire counterweight counterclockwise to adjust the weight in grams and gently place the stylus and entire cartridge onto a stylus force gauge, which will clamp to your turntable platter.
Once you’ve set your tracking force, you can now turn on the anti-skate setting and match it in grams to your tracking weight. If your tracking weight is 1.5 grams, you’ll want anti-skate on 1.5 grams as well.
By following these steps, you can ensure that your phono cartridge is properly balanced and set up for optimal sound quality and longevity.
Adjusting Vertical Tracking Force (VTF)
After mounting and connecting your cartridge, it’s time to set the vertical tracking force (VTF). This refers to the amount of weight that the stylus exerts on the record’s groove. Setting the VTF correctly is crucial for optimal sound quality and to prevent damage to your records and stylus.
There are a few different methods for setting VTF, but one recommended way is to use a digital stylus force gauge. This type of gauge is accurate to within .001 gm and comes pre-calibrated from the factory. To use it, turn off your turntable and place the gauge on the table with the left side against the spindle. Press the power button on the gauge and wait until the readout shows all zeros. Lower the stylus onto the marked measuring circle on the right-hand side of the gauge. Make sure that your turntable’s queuing lever is in the down position so that the full weight of the cartridge/stylus is on the gauge. The display will show you the current VTF in grams.
Adjusting VTF involves finding a setting that yields the lowest possible total harmonic distortion (THD) across both high and low frequency test tones. The Analog Magik test LP contains two test tracks for VTF calibration, one with a high-frequency test signal and one with a low frequency. Repeat the measurement by using different tracking force levels. You may discover that different VTF settings will cause THD% to go up or down between the two frequencies.
Once you have found the optimal VTF, adjust it using the sliding weight on your tonearm or by adjusting a setting ring on your tonearm assembly. Check your VTF again using the digital stylus force gauge to ensure that it is set correctly. It may take some trial and error to find the right setting, but once you do, you’ll notice a significant improvement in sound quality and less surface noise from your records.
Note that there are many factors that can interfere with this test method, such as cartridge quality, stylus shape, tonearm bearing chatter, resonance, and other uncontrollable factors. If you’re having trouble finding an optimal VTF using this method, more rigorous test methods such as sine wave observation or using other test tones may be needed.
