What You Will Need
- Turntable
- Strobe disc or smartphone app with a strobe function
- Screwdriver (usually a Phillips head)
Step 1: Understand the Basics
Before diving into the adjustment process, it’s essential to understand the basics of how turntable speed works. Most turntables have two adjustable speed settings: 33 1/3 RPM and 45 RPM. The speed is controlled by a motor that spins the platter on which the record sits. By adjusting the speed, you can ensure the correct playback rate of your vinyl records.
Step 2: Verify the Correct Speed
The first step is to verify if your turntable is running at the correct speed. To do this, you will need a strobe disc or a smartphone app that has a strobe function. Place the strobe disc on the turntable and set the speed to 33 1/3 RPM. Activate the strobe function on the app or point a light with a frequency of 50 or 60Hz at the strobe disc. Observe the markings on the disc. If the markings appear stationary, the turntable is running at the correct speed. If not, proceed to the next step.
Step 3: Access the Speed Adjustment Controls
Locate the speed adjustment controls on your turntable. These are usually located underneath the platter or on the outside of the turntable’s housing. Consult the user manual for specific instructions on where to find these controls for your particular model. Once located, you can proceed with making the necessary adjustments.
Step 4: Adjust the Speed
Using a screwdriver, carefully turn the speed adjustment screws to make the necessary changes. To increase the speed, turn the screw clockwise. To decrease the speed, turn the screw counterclockwise. It’s crucial to make small adjustments and then recheck the speed with the strobe disc or app after each adjustment. This way, you can fine-tune the speed to ensure it is accurate.
Step 5: Repeat the Verification Process
After making adjustments, repeat the verification process using the strobe disc or app. Place the strobe disc back on the turntable, set the speed to 33 1/3 RPM, and activate the strobe function. Observe the markings on the disc. If the markings now appear stationary, congratulations! Your turntable speed has been successfully adjusted. If not, continue to make small adjustments until the speed is correct.
Adjusting the speed of a turntable is a straightforward process that can significantly enhance your listening experience. By understanding the basics, verifying the speed, accessing the adjustment controls, and making careful adjustments, you can ensure your turntable is running at its optimal speed. Dust off your favorite vinyl records and enjoy the warm, high-fidelity sound that only a turntable can deliver!
