to the

high -output
X-
Series MC
cartridge line.
On old, well
-played
records, where
the
upper
groove walls
have
been polished
smooth
by conventional
stylii, the
X5-
MC's radical
new stylus
reads
deep into
the groove
to
extract subtle
musical de-
tails that
have remained
untouched
since
the day
the record was
pressed.
The
cartridge
offers
an incredible
frequency
response
of
20 to 45,000
Hz, +4/ -1.5
dB.
The
Ortofon X5 -MC phono cartridge
uses the proven high-
output moving -
coil drive system and aluminum
-tube
cantilever
from its predecessors,
the X 1-
MC and X3
-MC. However, by
adding
the radical new Fritz
Gyger II stylus,
the new
X5 -MC cartridge
delivers incred-
ibly accurate reproduction
of subtle
de-
tails, more focused imaging,
and greatly
improved tracking
ability.
The
X5 -MC
enjoys all the
key sound
quality advantages
of
moving
coil de-
sign with
none of
the practical
disadvan-
tages.
It benefits
from
an extremely
low
moving
mass for
optimum
high -fre-
quency performance
and a low
internal
impedance
to avoid
possible
cable/
preamp
problems.
The cartridge
is manufactured
using
a proprietary
Ortofon
coil-
winding
ma-
chine that winds wire
that is much
thin-
ner
than
would
be possible
to wind
by
hand.
The
coils are wound
on
a high,
rigid
X- shaped
armature
with hollow
arms that weighs
a mere 0.0012
grams.
Those
factors
enable the X5
-MC to have
a larger
number
of
windings
than a con-
ventional
moving
coil, yet
achieve a
significantly
lower
moving
mass.
Other
important
features
include
Ortofon's
wide
-range damping
system
for accu-
rate
control of
the moving
parts.
The
Ortofon X5 -MC
carries a sug-
gested
retail price
of $300. All
three
of
the X- Series
cartridges are now
also
available in P -Mount versions.

St., Plainview,
