How To Measure Phono Cartridge Output

To measure phono cartridge output, you’ll need a multimeter. This tool measures voltage, current, and resistance, and is essential for accurately testing the output of your cartridge.

Here’s a step-by-step guide to measuring phono cartridge output with a multimeter:

1. Remove the wires and cover of the cartridge.

2. Measure the resistance between the pins on either side of the cartridge using the multimeter.

3. Set your multimeter to 10,000 ohms.

4. Check the continuity of the phono cartridge by connecting the multimeter to the white (L) and blue (LG) pins. The reading should be above 100 ohms and 10,000 ohms.

5. Connect the multimeter’s leads to the green (RG) and red (R) pins. The reading should be above 100 ohms and under 10,000 ohms.

6. Check that the reading from step 5 matches the reading from step 4.

7. Connect the multimeter’s leads to the red and white pins. The reading should say “open” or “infinity.”

8. Connect the multimeter’s leads to the green and blue pins. The reading should also say “open” or “infinity.”

9. If you get different results from any of these steps, it means your phono cartridge is defective and needs to be repaired or replaced.

It’s important to note that if the pins on your cartridge are dirty or corroded, this method may not give accurate readings. Make sure to clean them before testing.

Understanding Phono Cartridge Output

Phono cartridge output refers to the electrical signal that is generated by the cartridge as it tracks the grooves of a vinyl record. This signal is then amplified and converted into sound by the rest of the audio system. The output of a phono cartridge is typically measured in milli-Volts (mV), and can vary depending on the type of cartridge.

Moving Magnet (MM) or Moving Iron (MI) cartridges typically produce a maximum output of 5mV, although figures can range from about 2.5mV to more than 7mV for DJ cartridges. Moving Coil (MC) cartridges, on the other hand, produce a much lower output, typically around 0.5mV.

To accurately measure phono cartridge output, it’s important to use a multimeter, which can measure voltage and resistance. The resistance between the pins on either side of the cartridge can be measured using the multimeter, with readings above 100 ohms and under 10,000 ohms indicating proper continuity.

It’s important to note that dirty or corroded pins on the cartridge can affect the accuracy of these readings. If any discrepancies are found during testing, it may indicate that the phono cartridge needs to be repaired or replaced. Overall, understanding phono cartridge output is crucial for optimizing your vinyl listening experience and ensuring that your audio system is functioning properly.

Tools Needed For Measuring Phono Cartridge Output

To measure phono cartridge output, you’ll need a multimeter. This tool is essential for accurately testing the voltage, current, and resistance of the cartridge.

In addition to a multimeter, there are a few other tools that can help you install and align your cartridge properly. The Pro-Ject Align it DS2 cartridge alignment tool is an essential tool for aligning the cartridge and ensuring that it tracks record grooves well. The Pro-Ject Measure it E stylus force gauge helps you set the correct tracking force, reducing wear and tear on the stylus and your records.

If you have specialized cartridges that show a different impedance or cartridge loading, you’ll also need an external preamp with variable loading, like the Pro-Ject Tube Box DS2. This adjustable preamp can help amplify the output from a variety of cartridges and ensure that you get the best sound quality possible.

Interpreting The Results Of Your Measurements

Once you’ve completed the steps above and have accurate readings from your multimeter, it’s time to interpret the results. Here’s what you need to know:

Resistance: The resistance measurement between the pins on either side of the cartridge indicates the health of the internal wiring. If the measurement is too high or too low, it could indicate a problem with the wiring.

Continuity: The continuity measurement between the white (L) and blue (LG) pins checks the left channel, while the measurement between the green (RG) and red (R) pins checks the right channel. If the readings are within the range specified in step 4, it means that the cartridge is functioning properly.

Open Circuit: The open circuit measurements between the red and white pins, as well as between the green and blue pins, indicate that there is no connection between those pins. This is normal and indicates that those pins are not used in this type of cartridge.

By following these steps and interpreting your results correctly, you can accurately measure the output of your phono cartridge and ensure that it’s functioning properly.

Troubleshooting Common Issues With Phono Cartridge Output

If you’re experiencing issues with your phono cartridge output, there are a few common problems that could be the culprit. Here are some troubleshooting tips:

1. Low output: If your cartridge is producing a weak or low output, the first thing to check is the stylus. Make sure it’s clean and not worn out. If it’s dirty, use a stylus cleaning brush to gently remove any debris. If it’s worn out, you’ll need to replace it.

2. Distorted sound: If your sound is distorted, it could be caused by a misaligned stylus. Check the alignment of your cartridge and adjust it if necessary.

3. No output: If you’re not getting any sound at all, check the wiring connections to make sure they’re secure and properly connected. It’s also possible that your cartridge is damaged and needs to be replaced.

4. Uneven output: If your sound is uneven, it could be caused by a damaged or worn-out cartridge. Check the stylus and replace it if necessary. You can also try adjusting the tracking force or anti-skate settings on your turntable.

Remember, if you’re unsure about any of these troubleshooting steps or if you suspect a more serious issue with your phono cartridge, it’s always best to consult a professional technician for help.

Tips For Maintaining Optimal Phono Cartridge Performance

Maintaining optimal phono cartridge performance is crucial for getting the best sound quality from your vinyl records. Here are some tips to help you keep your cartridge in top condition:

1. Clean your cartridge regularly: Dust and dirt can accumulate on the stylus and affect the sound quality. Use an antistatic record brush to remove dust from the record surface before every use, and use a stylus fiber brush to clean the diamond tip before and after playback of each record.

2. Avoid using solvents: Ortofon, a leading manufacturer of phono cartridges, does not recommend using solvents to clean your records or stylus. If necessary, use lukewarm demineralized water with a dash of sulphonic soap to wash your records.

3. Use a stylus guard: Always mount the stylus guard onto the cartridge when it’s not in use to avoid accidental damage to the stylus or cantilever.

4. Replace or resharpen your stylus when necessary: A worn or damaged stylus can affect the sound quality of your records. Look for visible damage, thin sounding playback, and skips or scratches as signs that your stylus may need replacing.

5. Invest in a record cleaning machine: A good record cleaning machine can remove deeper infusions of grease, mold, and grime from your records and add years of listening life by keeping them in good shape.

6. Be careful when changing cartridges: Changing cartridges can be tricky and delicate work. If you’re not confident, it’s worth paying someone to do it for you.

By following these tips, you can ensure that your phono cartridge is performing at its best and getting the most out of your vinyl collection.
