At Pro-Ject we go to great lengths when designing new turntables to get the best quality sound possible. One of the ways we can improve sound quality is by isolating the motor to avoid motor vibrations, or rumble, being transferred through the deck and ultimately your ears.
The Debut and 1 Xpression series of turntables feature a suspended motor design that requires the two transport screws to be removed for optimum sound quality.
Fortunately this is an easy process:
Step 1 - Remove the platter
Step 2 - Remove the 2 transport screws which secure the motor during transportation
Step 3 - Replace the platter
You should now experience your quality turntable free of vibration and rumble.
