Numark Industries PRO TT-1 Turntable User Manual


 
PRO TT-1
27. Anti-Skate Control - This applies inward force to the
tonearm so it doesn’t skip outward across the record due to
the centrifugal force of the record spinning. Cartridge
manufacturers usually specify the proper setting of this.
28. Tone Arm Height Adjust - This allows the tone arm to
be properly align with the platter surface.
29. Height Lock - Prevents accidental adjustment if the
height.
30. Counterweight - Adjustment creates the proper
downward pressure of the stylus to the record. Attach
now by sliding the counterweight onto the rear of the
tonearm. Twist it lightly and it will screw onto the rear shaft
of the tonearm.
Tonearm
Counterweight
The following explains proper counterweight and
anti-skating set up. Cartridge manufacturers usually specify
the proper settings.
(1) Remove the stylus protector, do not touch the
stylus tip during the adjustment.
(2) Set the cueing lever to the lower position so it does
not effect tone arm height.
(3) Release the arm clamp and lift the tonearm from the
arm rest so it moves freely.
(4) Rotate the counterweight until the tonearm is
approximately balanced horizontally (floats freely).
(5) Refasten the tonearm with the arm clamp.
(6) Hold the counterweight stationary
with one hand and rotate only the
stylus-pressure ring to bring the
number "O" of the ring into alignment
with the center line on the tonearm
rear shaft.
(7) Rotate the counterweight with
scale ring clockwise to the correct
stylus pressure following the
manufacture's recommendation.
Note: Failure to follow recommended stylus pressure
can damage both the stylus and record. This can also
seriously degrade performance.
(8) Set the anti-skating control knob (27) to the same
value as the stylus pressure, unless your manufacturer
specifies otherwise.
