Q:
What types of surface are recommended to be optimally effective
for mounting the ball bearings on? |
|
Stainless
steel is a very hard compound, and the further the ball bearings
penetrate into the surface underneath them, the less effective
their ability to block the transfer of the vibration into
the outer body will be. For this reason we recommend the hardest
possible surface you can find - instrument glass is optimum,
some dense hard woods or ceramic materials can also be used.
Isonoe sell cost-effective accessories designed to seat the
isolators effectively: |
A
pack of 4 discs made from instrument glass - these glass discs
can be seated either upon a conventional table or stand, or
they fit inside our Sorbothane "coasters": |
Sorbothane
"Coasters" - used in this application the turntable's
base will be extremely well secured. These coasters can be
used in their own right as a vibration-damping accessory for
conventional turntables, or they can be implemented to make
an ideal base for the Isonoe Isolation System providing another
level of isolation. |
|
| Q: How far can
I screw the Isolators into the threads on the player's base? |
|
A
soft, compliant bushing has been fitted around the thread
to seat the hub optimally on your player. If ride-height adjustment
is needed, you will see that the bushing compresses the more
you twist the bolt clockwise into the thread. After a couple
of turns the bushing is fully compressed, and cannot be inserted
further into the thread - this supplies around 3mm of travel
in and out of the thread for spirit-level adjustment. |
|
| Q: Why is the Isonoe
Isolation System expensive? |
|
In
order to machine raw billets of magnesium alloy into a precision
tolerance product, an engineering facility with multi-axis
CNC machines typically costing several hundred thousand pounds
each must be used; also, a specific grade of magnesium alloy
is used for its acoustical properties, and as a result of
both these criteria the product is never going to be cheap
wherever it is manufactured in the world. We could have made
the system from plastic or GRP to save cost, but it would
not have been anywhere near as effective. If you consider
the price to be high we would suggest showing the product
to your local machinist and obtaining their opinion. |
