Dual pivot bearing design – why?

The Enterprise arm is a performance leader by virtue of it’s

innovative dual pivot bearing on the horizontal axle (which governs

the arms vertical movement). This design is similar in many

respects to uni-pivot designs – low friction and high decoupling

which give excellent defi nition and transparency. However

uni-pivots can be fi ddly to set up and because of their relative

instability exhibit a mediocre bass performance. Dual pivot design

has all the advantages of uni-pivots but none of the drawbacks.

Vertical movement of the arm is handled by the dual pivot and

horizontal movement by our usual highly specifi ed conventional

bearings.

Handles like a conventional gimballed

arms

You should handle the arm in exactly the same way as a

conventional gimballed arm. In other words you do not need

to worry about setting up azimuth and balancing the arm. The

azimuth has already been set, such that the headshell is parallel to

the arm mounting surface. We strongly recommend that you never

adjust the factory setting even though it is possible via the pivot

screws. Correct azimuth setting is tricky at the best of times and

unless an extremely careful record is kept on the original factory

settings the arm will probably end up not working correctly. If

in trouble see technical support on our web site www.originlive.

Having said this it is recommended to slacken off the azimuth

clamping screws NOT the azimuth adjuster screws. Slackening

the clamping screws has the effect of increasing the performance

signifi cantly.

The pivot points will “self centre” by sliding into the bottom

with very low friction bearings.

DO NOT TOUCH THESE SCREWS
they clamp in the retaining rings which
prevent the arm coming apart

- loosing can result in breaking arm wires.
