Longitudinal

balance

adjustment

While

playing

the

record,

the

weight

of

the

tonearm

is

supported

by

the

arm

pivot

and

only

tracking

force

is

applied

to

the

stylus

tip.

To

accomplish

this,

the

tonearm

must

first

be

balanced

horizontally,

with

the

tracking

force

indicator

set

at

“O”.

*2

Tracking

force

After

the

longitudinal

balance

adjustment,

apply

the

recommended

tracking

force

weight

so

that

the

stylus

tip

will

trace

the

music

groove

accurately.

*3

Overhang

In

record

playing,

because

of

the

pivoted

design

of

the

tonearm,

the

stylus

tip

can

be

perfectly

tangent

to

the

music

groove

at

only

one

point

of

the

record.

At

all

other

portions

of

the

record,

there

is

a

slight

deviation

of

the

stylus

from

tangency.

This

is

called

the

tracking

error,

and

introduces

minute

errors

in

the

amplitude

and

timing

of

the

reproduced

signal

as

compared

to

the

original,

and

other

forms

of

distortion

which

may

be

introduced

depending

on

the

cartridge

and

stylus

design.

Tracking

error

is

minimized

by

the

selection

of

an

optimum

“off-set”

angle

and

“overhang”

distance.

Overhang

is

the

distance

between

the

stylus

tip

and

the

center

spindle.

This

overhang

adjustment

is

made

at

the

time

of

installing

a

particular

cartridge,

while

the

off-set

angle

is

fixed

by

the

manufacturer

of

the

tonearm.

*4

Anti-skating

compensation

While

the

record

is

being

played,

the

frictional

force

between

the

record

groove

and

the

stylus

produces

a

force

that

tends

to

drive

the

tonearm

toward

the

center

of

the

record.

The

anti-skating

compensation

cancels

the

above

mentioned

force,

and

is

applied

in

accordance

with

the

tracking

force.

Incorrect

anti-skating

compensation

results

in

sound

distortion

and

uneven

wear

on

both

the

stylus

and

the

record.
