Realistic LAB-2100 - HINTS FOR BETTER SOUND; Sound Quality Tips; MAINTENANCE; Cleaning and Dust Management

HINTS FOR
BETTER
SOUND
Howling:
Cartridges
are sensitive
and may
pick
up
slight sound
pressure
or
vibrations
of the speaker
coming
along
the
floor or through the air.
This
results in howl. Therefore,
location
of
your
Turntable
is important.
Find
a
location where
it
will be
stable and
free from vibration.
Induction
Hum:
Your turntable
utilizes
a brushless DC
FG servo.
motor
to reduce
inductive hum. lf
you
notice annoying
hum, it may be caused
by an
electromagnetic
field
produced
by motors
or
transformers
used
in other
products.
Do
not
place
the
Turntable
near such
products.
To
prevent
the
Turntable
from being affected
by
the
power
transformer of
your
amplif
ier,
receiver
or
tape
deck,
position
the
Turntable
on
the
side
opposite
the
power
transformer.
Record Care
When
handling
a record, always
hold it by
its edge and center
label area. Never
touch the
groove
surface.
Make it
a
habit to return records
to their
jackets
immediately after use.
Store
the records in a
vertical
position
and
protect
them
from
extremely high and
low
temperatures,
high humidity, and direct
sunlight.
MAINTENANCE
Dust and
Dirt:
Because
records carry
dust-attracting
static
charges,
they
should
be
cleaned before
use.
Playing a
dirty
record
grinds
dust
against
the record
walls
until
it wears away
the high
frequencies
and
increases
background
noise. The
most
effective cleaners
use an
ionizing
formula
to remove
the static charge
and
a cut
velvet
pad
to lift
particlesfrom
the
groove.
Occasionally
you
will
need
to remove dust
and dirt
from the
needle. For
best
results, use
Radio Shack's
stylus
cleaner
and brush Cat.
No. 42-1074.
To clean
the stylus,
brush
for-
ward very
gently
to remove
the dust. Brushing
from
front-to-back or
side-to-side
may
cause
permanent
damage. Avoid
touching
the stylus
tip when cleaning.
Your local
Radio Shack
store
has a
complete
line
of stylus
and record care
accessories.
Cabinet
and
Dust Cover
lf the cabinet
or
dust cover
requires cleaning,
use
a soft, damp cloth
(do
not use
solvents).
Don't
use
insecticide, benzine
or thinner
near the
cabinet.
Stylus
Replacement
The diamond
stylus
of the
turntable can
normally
play
for about 250
hours.
However, when
sound
becomes
noisy,
check
the stylus
for wear. lf
worn
out,
replace it
(refer
to Figure
10).
The
worn
stylus will
damage
the
record
permanently.
lt's
better
to
replace
your
stylus than
to replace
your
record
library.
