The Origine tonearm and its adjustments
The following section will explain the different adjustments of the Origine unipivot tonearm. The proper
functioning of your Origine turntable and its level of performance when reproducing music greatly depends on the
fact that all the following parameters have been calibrated precisely!
The Origine tonearm is a lightweight unipivot design. There is a moveable weight attached to its armtube
that we like to call the Olive. The primary role of the olive is to cut the armtube in two segments, effectively
getting rid of unwanted armtube resonances. For phono cartridges of high compliance we have found that the
sonically ideal position is in the center of the armtube. However owners of medium and low compliance
cartridges are invited to experiment with olive positions closer to the headshell as the proximity of the olive may
simulate a higher effective mass and enhance the tonearm / cartridge match. Remember to always re-calibrate
the VTF after any olive position change!
Attention!
If you have purchased your Origine turntable with the optional Ortofon 2M Blue cartridge know
that it has been pre-installed and calibrated at the factory which means that the VTA and azimuth
adjustments were already performed on the Origine tonearm.
Phono cartridge installation procedure
-
Carefully mount your phono cartridge to the tonearm headshell using the appropriate mounting
hardware. Make sure you keep the stylus guard in place during the whole process until you are
ready for the final calibration step.
-
Secure the cartridge lightly to the headshell so it can be moved for the precision calibration
-
Using needle nose pliers connect the tonearm phono leads to the cartridge.

-
Do not install the anti-skating weight pins at this time.
-
Remove the stylus guard
-
Perform a tracking force pre-
setting according to your phono cartridge manufacturer’s tracking
force recommendation.
Geometry calibration
Note:
The calibrator disc alignment with the tonearm pivot shaft is performed with the tonearm tube
assembly removed.
The tonearm wiring is very fragile please handle with great care.
Before
removing the tonearm from its pivot shaft PLEASE RE-INSTALL THE STYLUS GUARD!
-
Lift the tonearm off from its pivot base and set it just near behind the table without disconnecting
the 5-pin tonearm harness connector.
-
Place the supplied Calibrator disc on the platter over the spindle.
-
Position the Calibrator disc so the black line is lining up with the tip of the pivot shaft.
