1. Unpacking
Open the box carefully and remove top covers.
The tube with vertical bearing points is packed separately (tube assembly) on the top of the box.
Please do handle with care and when put aside, ensure that nothing is touching the bearing points.
Bear in mind how you will handle the termination box and output cable.
The horizontal bearing assembly is permanently mounted on the main VTA arm tower. This is
blocked during transport. (Fig. 2)
First remove the armbase and prepare it for fixing onto the turntable. Be sure that the armboard on the
turntable has the correct cut-out (main central hole must be 40 mm in diameter).
2. Basic set up
Armbase:
Mount the armbase on the turntable. If the pre-cut has a thread, then use three screws and fix them
from the top through the armbase into the armboard thread. A second way is to use a ring underneath
and fix three screws into this ring, which will then hold the armbase very tightly. Be sure that you
position the armbase so as to give access to an Allen key for fixing arm into armbase (towards the
back of the turntable). Also check, when mounting the arm on other turntables, that you allow enough
clearance for counterweights and correct position of the tube in relationship to the platter. Due to the
bearing construction, there is only a limited arc which the arm tube can travel in a horizontal way.
Rotation of the VTA arm tower of the arm, to achieve the correct distance of 264 mm, is done with a
protractor after the basic setup.
VTA arm tower:
Insert the VTA arm tower into the armbase. Ensure that the height is such, that the top surface of the
platform holding cueing device is at the same height as the record. Fix it with an Allen key. The
vertical bearing cups should be at the same height as the record. Also check that the VTA adjustment
is in the middle position, to allow fine VTA adjustment up and down 5 mm each way.
With 1.5 mm Allen key, release the small ring which is on the fixing pillar below the VTA arm tower.
Now it will drop down and touch the armbase. Fix the ring again and release the VTA arm tower.
You now have the correct height but you can freely rotate the VTA arm tower horizontally. Rotate it
to such a position that the distance from the centre of the record to the centre of the horizontal bearing
is 264 mm. (Use protractor by gently pulling apart trying to achieve max distance) Now fix VTA
arm tower. (Fig.3)
