Please note that to make super-fine adjustments, press either the top speed increase button or the bottom
speed decrease button once. Each click adjusts the speed 0.1RPM at the spindle. Given that the spindle to
platter ratio is approx. 1/10, each click is adjusting the speed by 1/100
th
of an RPM. This is only practical for
very fine adjustment.
For adjustments of a greater magnitude, press and hold either the top speed increase button or the bottom
speed decrease button for 5 seconds. The speed will either increase or decrease, depending on which button
you are pressing. When you are satisfied with the speed, do not press any buttons for 60 seconds. At this
point, the new calibrated speed will be stored in the turntable’s memory (ROM) and will be the new setting
from that moment onwards, even if the power is turned off.
Please note that the Helix One is a ‘set and forget’ design, meaning it has been designed to hold its
performance parameters and not need adjusting, so it is very rare that a turntable will require any speed
adjustment but the functionality is there in the event that it’s needed.
Each Turntable has a Serial Number
Each Döhmann Audio Helix One Mk2 turntable has a unique Serial Number that is recorded in the
manufacturer’s database along with all the information pertaining to that specific unit. The Serial Number
starts with a “DA” and can be found on the turntable’s identification tag on the rear panel as shown in the
image below.
