If your ICE1 turntable is spinning too fast or too slow, your records may sound distorted or off-pitch. While the RPM switch can handle most speed adjustments, fine-tuning the motor speed can restore precise playback. This guide explains how to safely adjust the motor and why it affects playback speed.
Why Adjust the Motor Speed?
The motor drives the turntable platter, determining how fast your vinyl spins. If the motor rotates too fast or too slow, the record will play at the wrong pitch and tempo, making music sound unnatural or distorted. Adjusting the motor speed corrects minor deviations caused by belt tension, motor wear, or manufacturing tolerances. By turning the motor’s calibration holes, you can ensure the platter spins at the correct 33 1/3 or 45 RPM for accurate vinyl playback.
Step-by-Step Guide to Adjust Motor Speed
Tools You’ll Need
Screwdriver set (Phillips/flathead)
Small flathead (1-head) screwdriver for motor adjustment
Flashlight (optional, for better visibility)
Step 1: Prepare the Turntable
Remove any record and the record pad.
Secure the tonearm to prevent damage during adjustment.
Turn the ICE1 turntable over to access the bottom panel.
Step 2: Open the Bottom Panel
Loosen the 3 screws on the bottom key board (refer to the numbers marked in the picture/diagram).
Gently lift the bottom plate to expose the motor and internal components.
Step 3: Locate the Motor and Adjustment Holes
The motor is usually highlighted or circled in diagrams.
The motor has two calibration holes:
“L” hole → adjusts 33 1/3 RPM
“H” hole → adjusts 45 RPM
Step 4: Adjust the Motor Speed
Make sure the speed selector is set to the corresponding RPM (33 or 45).
Insert a 1-head screwdriver into the matching adjustment hole:
Turn counterclockwise → increases speed
Turn clockwise → decreases speed
Make small adjustments at a time, testing playback after each turn to avoid over-correcting.
⚠️ Tip: Adjust only one hole at a time depending on the record you plan to play.
Step 5: Test and Fine-Tune
Reassemble the bottom plate lightly.
Play a record or use a strobe disc or smartphone app to check the RPM accuracy.
Repeat adjustments until the platter spins at the correct speed.
Maintenance Tips
Keep the motor and surrounding area clean to prevent dust or debris from affecting speed.
Apply a drop of light oil to the motor shaft if it feels dry.
Check the belt for wear and replace if necessary to maintain stable rotation.
Store the turntable in a dry, dust-free environment to protect both the motor and your vinyl records.
Conclusion
Adjusting the motor speed on the ICE1 turntable ensures your vinyl plays at the correct pitch and tempo. By following these steps, you can correct deviations that the RPM switch alone may not fix. Proper maintenance and careful adjustments will keep your ICE1 delivering accurate, high-quality playback for years to come.
