2. Carefully rotate the counterweight until the armtube balances out, i.e.
floats horizontally parallel to the surface of the turntable. The arm
should return to the balanced position if it is moved up or down. This
adjustment must be done carefully. Do not forget to remove the
cartridge protection cap if fitted.
3. Once the arm is correctly balanced return it to the rest. Hold the
counterweight so it cannot rotate and your setting is not lost, and
gently revolve the downforce scale ring only until the zero is in line
with the white line. Check whether the arm still balances out.
4. Now rotate the whole counterweight and scale ring together counter
clockwise (seen from the front) to adjust the downforce according to
the cartridge manufacturer's recommendations. One mark on the
scale represents 1 mN (0.1g) of downforce.
Note: The recommended downforce for the factory fitted cartridge is
20mN / 2.0g.
Anti-skating (bias) adjustment
The TT50 features a magnetic anti-skate which applies a non contact
force to the arm to counter-act the natural force applied by the record as
the stylus is forced towards the center of the spiralling groove.
The anti-skate adjustment has been designed so that it is matched to
the tracking force adjustment (higher tracking force requires higher anti-
skate) and should be set to the same numerical value.
Setting the correct anti-skate ensures that the average pressure on both
sides of the stylus is equal for best stereo separation and tracking
ability.
Turn the dial anti clockwise to apply magnetic anti-skate so that the
metal pin indicates the same reading as the downforce setting
previously set.
Note: The anti-skate for the supplied cartridge is 2.0g. This is not a
critical setting and an accuracy of +/- 0.5g is usually quite sufficient.
Your turntable is now ready for use.
7. Carefully remove the protective cover from the supplied cartridge.
Cartridge downforce adjustment
The supplied counterweight is suitable for cartridges weighing between
3.5 and 5.5g.
An alternative counterweight for cartridges weighing between 6 - 9g is
available as an accessory part, contact your Cambridge Audio dealer if
you need this part.
Before adjusting the downforce, first set the anti-skating adjustment to
zero.
1. Gently push and turn the counterweight onto the armtube stub. Lower
the armlift and position the cartridge in the space between arm rest
and platter.
