FEATURES
1.
Low
mass
type
tonearm
improves
trackability
and
fidelity.
The
head
shell
is
integrated
into
the
arm
tube,
with
its
a
connector
portion
located
at
the
base
of
the
tube.
The
construction
materials
for
this
tonearm
have
been
selected
very
carefully
to
reduce
the
effective
mass
to
the
bare
minimum.
As
a
result,
even
when
mated
with
a
high
compliance
cartridge,
the
low
end
resonance
frequency
(fo)
does
not
become
too
low
but
remains
optimum.
Clearer
sound
is
achieved
since
the
effects
of
record
war-
page
and
rotational
excentricity
are
eliminated
along
with
intermodulation
distortion.
Since
a
straight
shaped
tonearm
is
almost
symmetrical
from
side
to
side,
dimensional
or
mechanical
accuracies
are
improved.

making

possible.
2.
Replaceable
S-shaped
arm
tube
with
standard
4P
connector.
By
replacing
the
low
mass
arm
tube
with
the
S-shape
arm
tube,
the
virtually
all
head
shells
or
integrated
cartridges/
head
shells
can
be
utilized
on
the
DP-60L.
By
having
the
ability
to
use
the
widest
selection
of
cartridges,
your
audio
enjoyment
will
be
significantly
broadened.
3. Magnetic recording speed detection system.
The
turntable
platter
speed
of
the
DP-GOL
is
detected
by
DENON’s
magnetic
recording
detection
system.

is
high
enough
(1000
pulses
per
rotation)
to
allow
ultra
fast

of
the

virtually

The
4.
Auto-lift
mechanism
with
non-contact
record-end
sensor.
The
automatic
arm
lift
(auto-lift)
mechanism
functions
in
such
a
way
that
when
a
record
playback
is
finished,
the
tonearm
is
automatically
lifted
and
the
platter
rotation
stops.
This
eliminates
the
possibility
of
stylus
wear
by
leaving
it
tracking
the
lead
out
record
grooves.
At
the
end
of
play,
a
non-contact
record-end
sensor
senses
the
velocity
change
of
the
tonearm
with
an
opto-electronic
transducer,
eliminating
unnecessary
load
on
the
record
or
stylus.
Sound
quality
is
totally
unaffected
by
this
system.
5. Angular control motor lifts tonearm.
The
arm
lifting
device
employs
a
servo-controlled
angular
control
motor
developed
by
DENON,
for
ultra-smooth
and
silent
up
and
down
motion.
6. PLL servo control via a quarts crystal oscillator guaran-
tees speed accuracy of below 0.002%, and is almost totally
immune to variation of temperature, humidity, load condi-
tion or supply voltage fluctuation.
y
7. The combination of Bi-directional servo contro! and
electronic braking, together with rotational detection offers
the quickest, smoothest start, stop and speed change-
over.
8. Counterweight shaft is damped effectively to supress
partial resonance of tonearm body.
9. The turntable mat was developed through vibration
analysis through laser holography.
