TNRC
Base Material Stops Acoustic Feedback
If
you
have ever
experienced
howling-caused
by
acoustic
feedback-you
know
it
is
the
last
thing
you
want
your
turntable
to
do.
But
with
ou
r
original
TNRc·
base material, it
is
the
last
thing
you
'll have
to
worry
about,
even at
high
volume
levels.
This
unique
anti-re
sonant
material is
high-molecular
compound
made
by
mixi ng
inorganic
compounds
and special materials.
Compared
with
ordinary
plastic
resins
or
particle
board,
TNRC
exhibits
strikingly
superior
resonance
attenuation
characteristics
and lo w
amplitude
of
the
vibration
as
well as
excellent
attenuation
to
t
he
vibration
of
the
base.

Technics
Non-Resonance
Compound
.
Ultra-Low-Speed Direct Drive Motor
The
direct-drive
of
this
unit
eliminates
the
belts, wheels,
and
other
drive
elements
required
by
conventional
systems. These
same belts and so
on
are
notorious
sources
of
vibration
,
resonance, and
cyclical
variations
in speed .
With
only
one
mov-
ing part, the
D.D.
system
does
away
with
these
sources
of
dis-
turbance
, to
provide
superbly
smooth,
constant
platter
rotation
.
Integral Rotor-Platter Structure
To
further
simplify
the
turntable
design, the
platter
and
rotor
are
formed
into
a single,
continuous
unit.
By
eliminating
a
linkage
point
, this prevents the
potentially
disturbing
effects
of
looseness
or
maladjustment
between
platter
and
rotor.
All Front-Panel Controls
The
advancement
to
complete
front-panel
control
marks
a big
step
forward
in
turntable
operation,
not
only
because
of
the
greater
convenience,
but
also because
of
the
greater
protection
from
dust,
as
the
dust
cover
can stay
closed.
Tonearm Cueing Controlled from Front Panel
The
tonearm
is raised and
lowered
softly
by
a
viscous-damped
cueing
lifter. Even
with
the
dust
cover
closed,
a
cueing
can be
easily
performed
as the
control
is
located
on
the
front
panel.
Fully-Automatic Operation
All
operations
in the SL-3300 are
completely
automatic,
yet
mechanical
movements
are
accurate
and
silent. Full
protection
to
records
and
stylus
tip
is assured.
With
the
memo-repeat
feature,
favorite
records
may
be repeated
up
to
six
times
,
or
indefinitely.
• Highly Sensitive Gimbal Suspension System
With the
high-precision
pivot
bearings
employed
for
the
horizontal
and vertical
journals
of
the
tonearm,
in
concert
with
the
adoption
of
the
gimbal
suspension
system, a
high-sensitivity
arm
of
less than 7 mg
friction
has been attained,
thus
making
it
possible
to
fully
realize
the
performance
of
high-compliance
cartridges.
• Independent Pitch Controls
Permits
record
speed (at
both
33-1/3
and 45 rpm)
to
be varied
by up
to
10%.
• Precision Strobe Illuminator/Pilot Lamp
With
the
built-in
strobe
illuminator/pilot
lamp,
accurate
speed
adjustments
can be
made
rapidly
and easily.
• Anti-Skating Force Mechanism
The
well-designed
anti-skating
force
mechanism
ensures
minimum
side
thrust
with
different
cartridges
and
guarantees
accurate
center-of-the-groove
tracking.
