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)
