/___ . , , "if . .

In the more than 100 years since Edison in-
vented the phonograph. a lot ol progress has
been made,

The L~07D was designed and developed with a
view to making an ultimate record playing
system, which converts the music information
cut in the record with 100% accuracy into an
electrical signal, in other words, it achieves
"perlect conversion" lrom the engraved groove
into the reproduced signal.

Various new techniques have been developed
and applied in the L-O7D to achieve this perfect
conversion".

However. any one of these techniques can-

* not exhibit its lull elfect on its own: they work

together to make a total system elfective. KEN-
WOOD's engineers are proud of the L-07D; it is a
high precision turntable which will give a new
appreciation of the capabilities of records.

The L-O7D was designed giving priority to
the lollowing.

1. High rigidity and good anti-vibration proper-
ties.

2. The three supporting points in the pickup
loop are extremely accurate.

3. High transient load characteristics.

4. High fidelity electrical signal transmission.

Super heavy metal-inserted cabinet with
complex structure providing high rigidity and
good antivibmtion properties

The cabinet has a complex structure which is
basically a double-layer structure and metal is in-
serted into important parts, so that the center at
gravity is lowered. the tonearm and the
phonomotor are completely supported and anti-
vibration properties are greatly improved.

The upper layer of the cabinet is made ol the
new ARCB material which can be precisely mold-
ed and has outstanding rigidity. Further, diecast
aluminum is inserted into important parts of the
upper layer. The lower layer at the cabinet is
made lrom mahogany complite which has
superior rigidity and anti-vibration properties.
Thus, the cabinet has very high rigidity and is
almost perlsctly vibration-free.

Dynamic compensated motor

The most important point in improving the
phone-motor is to remove cogging and torque
ripple. Theoretically, it is possible to build a
motor without torque ripple, but in practice such
a motor is impossible because ol machining ac-

kcuracy and viscous resistance. The motor coil
