INSTALLATION & SETUP
CONT.
HOW TO ADJUST THE ANTISKATE
cont.
The bias should be adjusted according to the tracking
force. We recommend you set the bias by use of an
appropriate test record, ie. those with tracking bands.
Do not use unmodulated grooves as they do not
create accurate vector forces.
Most test records use a principle of mistracking to identify
bias adjustment. We recommend you also use tools such
as a Wally Skater from WAM Engineering to set bias.
If mistracking is apparent, adjust the bias until minimum
mistracking is heard in both channels. If mistracking
appears in the right channel only, the bias is too low.
Move the weight down or add mass to the antiskate lever
arm. If it appears in the left channel only, the bias is too
high. Move the weight up or add mass to the antiskate
lever arm. If mistracking appears equal on both channels,
the trackability limit of the cartridge has been reached.
You may be able to reduce mistracking further
by increasing the tracking force to the maximum
recommended by the cartridge manufacturer.
