E. ANTI-SKATING:
A pivoted arm without an offset head would not be subject to skating force.
However, it will also have no correction for tracking error and the resulting
distortion is unacceptable. As soon as the arm's head is offset to lower tracing
distortion, skating force arises. Greater offsets result in greater skating force.
The 12 arm has a very small offset angle and therefore a very low skating
force to deal with.
After very careful listening tests we have determined that every tonearm we
tried sounded better with their mechanical anti-skating disabled and the tracking
force very slightly increased. All mechanical anti-skate devices add a negative
sound to the music because they are made of parts that can vibrate. We solve
the problem in a unique way:
As mentioned earlier, the arm wire applies the anti-skating force. The degree of
force applied can be adjusted as explained below.
To increase or decrease the amount of anti-skating force applied, simply unplug
the Lemo connector and twist it in the direction you want the force applied.
For example, to increase anti-skating force give the connector a
counterclockwise twist, unwinding the coiled wire. Likewise, to decrease the
force, give the connector a clockwise twist. Remember, the Lemo connector
can only be "adjusted" in increments of whole turns. If it is not, its key will not
line up with the groove in the receptacle.
We could go on discussing the pros and cons of how much anti-skate is correct,
but the sonic answer is very simple. Adjust the wire as mentioned above until
the tonearm drifts outward when set to neutral balance. When you push the
neutral balance floating tonearm towards the center of the record, it should push
back out towards the rim of the record. Very little force is needed to do this,
and the wire acts like a spring to supply this force.
If you try adjusting the anti-skate with a groove less record or a test record
you will ruin the twist in the wire and void your warrantee
Double check the horizontal balance, lateral balance, and tracking force and
adjust as needed. Increase the tracking force by 1/10 of a gram above the
cartridge manufacturers highest recommended force.
bortsett fra på ett punkt
Jeg tenkte feil i forhold til lange armer. Feil i form av at jeg ikke tok med i beregningen at en lengre arm festes lengre fra platetallerken (har ikke hatt en slik selv og antok at man brukte samme innfestningspunkt som originalen). Men det jo selvsagt slik at pickupnålen settes ned på samme punkt på vinylen, og tangent-feilen vil da bli mindre, og anti-skating krefter også mindre.
